The combustion products expand in the turbine with electricity generation and next fed into the burning chamber. The resulting combustion products consistently set in the economizer or the steam generator surface or contact surface condenser, surface gas heat exchanger, silencer and a chimney. The difference between the proposed installation from known is that it contains a battery of heat, is divided into hot and cold parts, and the economizer or the steam generator is connected to the hot part of the heat accumulator of surface or contact surface condenser is connected with both hot and cold part of the battery of warmth, and the drier is connected to the cold part of the battery heat. The invention allows to increase the capacity of 2-2,5 times, increase efficiency up to about 0.6-0.7, and CoE is. the crystals, 5 Il.

The invention relates to the field of heat and can be used in stationary energy and drive gas turbines that burn natural gas and liquid fossil fuels.

Known similar devices and methods of work with regeneration or disposal of the heat of the exhaust gas in the cycle of the installation. These units are gas turbine engines with energy and environmental steam injection or water (Askin L. A. gas Turbine installation with energy steam injection //Power construction. 1990. 2. S. 67-73). In them steam or water is fed into the combustion chamber and the turbine low pressure. Injection of steam produced in the boiler to recover heat from exhaust gases, increase the capacity of these installations on the 5090% efficiency at 2060% substantially reduce the temperature of the gas before the turbine or turbines, reduce emissions of oxides of nitrogen several times.

The disadvantages of these installations are the need for high quality water that does not contain mineral compounds, and lower efficiency compared to the efficiency of combined-cycle plants.

The closest in technical essence and the achieved effect to the proposed method of advocates /M A. Pikin, K. L. Khokhlov //Opening. Of the invention. 1997. 3), which increases its efficiency and environmental friendliness. He was adopted as a prototype.

This engine includes a compressor, a combustor, a gas turbine, afterburner chamber (afterburner), the output nozzle, ducts and piping for water injection.

The method is as follows.

Air from the atmosphere is served in the compressor, a part of the compressed to the maximum pressure of the air supplied into the combustion chamber, which serves the fuel. In the combustion chamber the fuel is burned with excess air coefficient 0,40,6 depending on the desired temperature of the products of combustion at the entrance to the gas turbine. Further, the products of combustion in a gas turbine dorogaya with the increase of the coefficient of excess air to 0.8 due to selected portions of air from the respective stages of the compressor on the air ducts. Further, the products of incomplete combustion of fuel injected into the afterburner chamber where dorogaya with excess air coefficient is greater than 1 by feeding it air from the compressor through the corresponding duct. Then the products of complete combustion of the fuel through the output nozzle is vented into the atmosphere. In forced mode alicastrum water injection in the compression stage and/or the camera.

The main disadvantages of this prototype are the need for large quantities of water, purified from mineral impurities, which are not recovered from the exhaust gases, the heat losses of water removed in the atmosphere along with products of combustion, reducing the rate of combustion of fuel in the combustion chamber due to the decrease of the coefficient of excess air in the combustion zone is less than one, the reduction of engine efficiency due to reuse a significant amount of fuel in the turbine and the afterburner, as energetically profitable to burn all the fuel in the combustion chamber, as well as two methods of reducing the temperature of the gases in the combustion chamber by reducing the excess air coefficient is below 1 and the injection of water, when the second method is energetically more profitable than the first.

The closest in technical essence and the achieved effect to the proposed device is a power plant with deep cooling of the combustion products, designed to improve its efficiency (A. S. Russia 1040192, CL F 01 K 25/00. Power plant with deep cooling of products of combustion /A. N. Lozhkin and C. B. Fungi //Opening. Of the invention. 1983. 33). She was adopted as a prototype.

This power plant sodany (regenerative) economizer, the turboexpander products of combustion from the generator, the surface (regenerative) heat exchanger and expander of the fuel gas generator.

The resulting combustion products are served in the gas turbine, where they work and lead in a movement of this turbine, along with the compressor and generator. After gas turbines operating with resistance of 0.2-0.35 MPa, the gases pass successively located boiling, dry and wet stage pressure economizer, where the heated coolant. Next, the cooled products of combustion in the economizer is sent to the expander products of combustion, where they do the work that used to generate electricity in the generator. After turboexpander cooled gases are served in the refrigeration consumer. The heated coolant in the pressure economizer is sent to the heat exchanger where it heats the fuel gas. The heated gas is fed into the fuel gas expander, tx2">

The main disadvantages of this prototype are marked decrease in the efficiency of the power plant due to the increase of the gas pressure for the gas turbine to 0,20,35 MPa in the installation of the products of combustion turboexpander, the dependence of the efficiency of the power plant from the outside temperature, as well as temperature, pressure and quantity of fuel gas supplied to the heat exchanger and the combustion products leaving the gas turbine, reducing fuel efficiency of a power plant due to the lower temperature of the fuel gas during its expansion in the expander entering the combustion chamber, and also increased the temperature of the refrigerant after expansion unit of the products of combustion as the heat get a small amount of fuel gas from a large volume of products of combustion through the intermediate heat carrier, is insufficient for effective cooling of these products of combustion in the pressure economizer before turboexpander.

Water from the cold side of the battery 30 is driven by the inlet 43 and 46 and the outlet 52 of the water through surface water-air heat exchanger 18 by the action of pump 32. The temperature of the circulating fluid adjust knob 65 is higher than the temperature of freezing. The air in the compressor 1 is compressed, its temperature increases. The cooling air produced in the compressor by the injection of water, which is supplied from the cold side of the battery by pump 32 through water pipes 45. The air temperature at the outlet of the compressor regulate above the dew point temperature controller 66. The cooled and humidified air fed into the combustion chamber 3. This camera comes more fuel through fuel line 27, which before serving, heat in toplivopotreblenie 26 and filtered in the filter 25. The temperature of the fuel regulating controller 42 changes the amount of hot water passing from the water economizer 6 and the water supply 37 through this toplivopodachej in the hot part of akkumulatoren fuel 28 and 59 air on command from the control excess air factor of 60. When burning gaseous and liquid fuels support controller the value of the excess air coefficient is equal 1,021,05 and 1,051,10 respectively. To reduce the temperature of the gases in the combustion chamber before defining it serves water from a water economizer 6 through the pipes 38 and 39. Water regulating controller 61 for determining the temperature of the gases in this chamber. Under the defining temperature is a temperature at which the combustion chamber is reliable, there is no dissociation of the combustion products, the content of oxides of nitrogen and carbon is formed within the acceptable range. This temperature is set by the test gas turbine installation. From the combustion chamber 3, the gases enter the turbine 2, where they work and drive the gas turbine, which transmits its power to the compressor 1 and the load 4. In this turbine serves more water out of a water economizer 6 through the pipes 38 and 40 to reduce the temperature of the gases therein to acceptable technical requirements.

A water economizer gases are sent through the pipeline 13 into the surface condenser 7, where they are cooled to a temperature below the dew point temperature. Thus water in the water path of the capacitor is served by the water supply pump 44 32 from the cold side of the battery 30, and assign it and condensate pipes 50 and 51 in the hot part of the battery. Then from the condenser 7 through the pipeline 14 and the exhaust gases down into the superficial gas heat exchanger 8, where water for heating gases supplied from a water economizer 6 and the water supply 41, and away from it in the hot side of the battery 29 to the water supply 49.

The temperature of the outside air to the compressor to regulate the regulator 54 is above the dew point temperature by changing the amount of circulating coolant through the heat exchanger. At negative ambient temperatures, when the temperature of the cold water approaches the freezing point, the sealing device 96 for the 9, 91, 92 and 93 in the contact-surface heat exchanger 69, where they warm the incoming air, the temperature of which is supported above the dew point temperature controller 54 changes the amount of circulating coolant through the heat exchanger. In both cases, the water from the heat exchanger divert the water pipes 94 and 95 in the cold part of the battery 30. Prepared the air duct 24 is served by the compressor 1, which increases its temperature and pressure as a result of compression. In this compressor, the air is cooled and humidified by water atomization similarly as it was described when considering the scheme in Fig.1, then it is sent via the air duct 75 in regenerative air heater 74, where increase its temperature by heat transfer from the exhaust gases. Heated air fed into the combustion chamber 3. Here sum more fuel prepared in the complex fuel preparation device 82 for combustion.

When the combustion air excess factor regulate the regulator 60 to the content or change the content of carbon monoxide in the combustion products for this camera. With this change the cost of fuel and air regulating device 28 and 59, respectively. From the combustion chamber 3 gases are served in the gas turbine 2, which is down more steam from the steam generator 79 and integrated fuel preparation device 82. The number of incoming vapor regulate the regulator 89 pressure steam pressure in the steam line 83. The resulting gas-vapor mixture is fired in the gas turbine 2 and puts it in motion, and with it the compressor 1 and the load 4. The exhaust gases in the turbine is directed through the pipeline 77 in regenerative air heater 74, where they heat the air, and pipeline 78 them down in the steam generator 79. The water in the steam generator served by the pump 31 from the hot side of the battery through the pipes 33 and 34. Regulate the steam temperature by changing the amount of water in it by the controller 86. The cooled gases in the steam generator further cooled in the contact surface condenser 70 where one of the battery 30 through the pipes 43, 98 and 99.

Below you can find a way to work a typical twin-shaft schematic of a gas turbine installation with a complex system of deep heat utilization and reduce harmful emissions into the atmosphere and variations of this method in accordance with Fig. 3. Air integrated air preparation device 113 is cleaned from dust and solid particles, cooled or heated, depending on its temperature, reduce its noise absorption, as in the above methods, and then served in the compressor low doubling 109 after the low-pressure compressor, supplied by pump 32 from the cold side of the battery through the pipes 43, 128 and 142. The temperature of the air before the high-pressure compressor 106 is adjusted by the regulator 144 above the dew point temperature by changing the number raspisivaem water. From the compressor low pressure air via the air duct 109 is served in the high-pressure compressor, where it is under compression again heated. This again humidify the air, and the temperature of its lower atomization of water in the duct 138 after compressor high pressure supplied by pump 32 from the cold side of the battery 30 through the pipes 43, 128, 142 and 143. At this temperature before regenerative air heater 74 to regulate the regulator 145 above the dew point temperature by changing the number raspisivaem water. The humidified and cooled air is heated in the regenerative air heater 74 to heat the exhaust gas and fed into the combustion chamber 3. This camera serves more fuel is prepared for combustion in an integrated device toplivopodachi. Hot water heated in the economizer heat of the exhaust gas, atomized in the pipeline 111 for regenerative air heater 74 to reduce the temperature of the gas is jwaamoj water. The coefficient of excess air in the combustion chamber reduces combustion of gas fuel to 1,021,05, and when burning liquid fuel to 1,051,10 recirculation of exhaust gases. For this purpose, the exhaust gases after a comprehensive gas treatment device 114 is supplied from the pressurized gas 16 into the suction duct 149 before the low-pressure compressor 105 through the recirculation pipeline 148. Moreover, the coefficient of excess air in the combustion chamber to regulate the controller 150 to the content or change the content of nitric oxide for the expander, depending on the amount of exhaust gases into the intake duct. After the combustion gases are directed to the gas turbine high pressure 108 through the pipeline 112, in this turbine they work and lead her into motion, and with it the high-pressure compressor 106. If the temperature of these gases exceed permissible under the terms of reliable operation of the gas turbine high pressure, the temperature regulating knob 62 by spraying water into the pipeline 112 before this turbine. The water in the spray device of this pipeline serves a water economizer 6 pipes 123 and 126. The exhaust gases in the high pressure turbine 108 Nanya dorogaya when the supply of air and fuel. Fuel available in the fuel line 136 from the integrated fuel preparation device 82 in the quantity required to raise the gas temperature above 700oC. While the temperature of the gases in the zone of the combustion chamber to regulate the controller 137, the change in the amount of fuel. The air down from the high-pressure compressor 106 via the air duct 138 in the quantity required for post-combustion products of incomplete combustion. Thus, the amount of supplied air adjust knob 139 content or reduce the content of carbon monoxide in the gas line 116 for a gas turbine low pressure. After afterburning combustion products is served in the gas low-pressure turbine 107, where they work and lead in a movement of this gas turbine, along with the low-pressure compressor 105 and the load 4. From the low-pressure turbine 107 gases are sent through the pipeline 116 in regenerative air heater 74, where they are cooled and move further through the pipeline 117 in the economizer 6. In this economizer exhaust gases are cooled, and the water is heated, which comes in its water path water 122 from the hot side of the heat accumulator of 29 under the action of the water pump 31. Chilled water EC is Gazoprovod 118. The work of this capacitor and the regulation of the temperature of gases behind it are described above in accordance with Fig.1. Next, the exhaust gases are directed to the expander 71 through pipelines 14 and 119, where they expand and produce work. However, these gases can be cooled to the freezing temperature of the condensate, and work to pass the low-pressure compressor 105 and the load 4. Before the release of combustion products in the flue pipe 10 they go through a comprehensive gas treatment device 114, where they warmed up, cleanse and reduce noise. The temperature of the flue gases at the mouth of the chimney increases above the dew point temperature by circulating heated air through the duct 146 in the pipeline 16 near the complex gas treatment device 114. In this case, the temperature of the gases at the mouth of the chimney regulate the controller 147, the change in the amount of hot air. The water temperature in the cold part of the battery reduces its cooling cold the leaving gases and air. When cooled gases water picked up by the pump 32 from the cold side of the battery 30, and serves on the pipes 43, 128 and 131 in the integrated heat exchanger of the gas treatment device 114 and away from it in the return water line 49 again in the cold part) is arsenia change the amount of circulating coolant. When the cooling water is supplied from the cold side of the battery 30 to the feed pipes 43 and 128 through surface heat exchanger integrated air preparation device 113 and return in the return water 130. If the chilled water temperature decreases below the allowable, then include a controller 129 that allows hot water from the discharge pipe 122 to 127 water in the intake water pipe 43, through which flows cold water, in an amount necessary to restore the temperature of this water. Processing of condensate produced in the integrated device disposing of the condensate, where the excess drain on the water supply 134. While restoring the reagents and receive semi-finished products or commercial products.

Below in Fig. 4 discusses the method of operation of a gas turbine installation with double-shaft scheme and complex system of deep waste heat and reduce harmful emissions into the atmosphere and its variants using contact-surface heat exchangers and steam generators. Air through the suction device 19 down in the contact-surface heat exchanger 69, where it is cleaned from dust, heat or cool, moisturize and reduce its noise. The ZAT is water tract served by pump 32 from the cold side of the battery 30 through the passage 43, 128, 91 and 93 and 43, 128, 91 and 92, respectively. Take away the water and drain the pipes 94 and 95, respectively, in the cold part of the battery. If its temperature falls below the allowable, the controller 129 passes hot water through water pipes 127 in the water pipe 91, which circulates cold water in the mixing of the coolant temperature of the water increases. In the low-pressure compressor 105, the air is compressed, its temperature increases. This air is cooled in the contact surface of the cooler 151, where it is fed via the air duct 109. The water in the water path of this air cooler is served by pump 156 of the water network pipes 153 and 157 via the contact-surface condenser 70 where it is heated by the heat of exhaust gases. Water atomization in the contact surface of the cooler 151 down from the hot side of the battery through the pipes 33, 162 and 163 under the action of the pump 31, and divert it from the water pipe 165 to the tank-mixer 166. The temperature behind the heater adjust regulator 172 above the dew point temperature by changing the amount of water supplied to the atomization of the water supply system 163. The cooled air down Vkontakte-surface air cooler 152, where down the duct 75. The water in the water path of this air cooler is supplied from the water tract of the previous cooler 151 to 154 water. Here it is again heated by hot air and direct to the consumer of hot water 36. The temperature of the water consumed regulate the regulator 158. In a spray device of the air cooler 152 water is fed by the pump 31 from the hot side of the battery through the pipes 33 and 162, and away from the tray for water lines 164 in tank mixer 166. Thus regulate the temperature of the air downstream of the air cooler controller 173 above the dew point temperature by changing the number raspisivaem water. Hot water from the tank mixer pump 166 170 serves on water 168 consumer warmth 169. The amount of warmth regulate the controller 171. The excess hot water is drained from the tank 66 through water pipes 167 in the hot side of the battery 29. The cooled and humidified air coolers 151 and 152 is fed to the combustion chamber 3 via the air duct 111. In this camera down more fuel complex fuel preparation device 82 through fuel line 85 and steam from the steam generator 79 on steam conduits 83 and 87. The fuel in this chamber burn gas when the coefficient of the regulator 61 by changing the amount of steam in the steam line 87. The products of combustion is supplied from the combustion chamber 3 through the pipeline 112 in the gas turbine high pressure 108, where they work and lead her into motion together with the high-pressure compressor 106. The temperature of the gases in the turbine is reduced to acceptable values by feeding it a couple of steam generator for steam line 174. In this case, the temperature of the gases therein govern controller 175, a change in the amount of steam this steam. Steam from the steam generator 79 fail in the heat exchanger integrated fuel preparation device 82, where the heated liquid fuel temperature below its vaporization in the heat exchanger, and to divert the steam in the gas turbine low pressure 107 or pipeline 78 for this turbine, depending on its temperature. When saturated steam shut-off device 177 is closed, and 178 open, he moves on to the line 176 in the pipeline 78. If the steam is dry, the locking device 178 is closed, and 177 - open, he enters the gas turbine low pressure steam line 84. Gas-vapor mixture is fired in the turbine and puts it in motion, and with it the low-pressure compressor 105 and the load 4, and then it is sent to the steam generator 79 where it gives RA 29 on the pipes 33 and 38. Thus regulate the temperature of the vapor regulator 86, the change in the amount of feed water supplied to the steam generator. The cooled gases in the steam generator further cooled in the contact surface of the capacitor 70 is below the dew point, where they fail through the pipeline 13. The water in the water path of the capacitor is supplied from the water mains pump 156 to 157 water and divert it to the water line 153 in the contact surface of the heater 151. In the spray device of this condenser water is supplied by pump 32 from the cold side of the battery through the pipes 43 and 159, and to divert water 161 in the hot side of the battery 29. The temperature of gases behind the condenser regulate the controller 160 below the dew point temperature by changing the amount of water supplied to the atomization of the water supply 159. After condensation of water vapor gases are sent through the pipeline 14 in the expander 71, where they do work, which is then converted into electricity in the generator 72. The temperature of gas in the expander further reduced due to their expansion. As a result, in the flue gases appear droplets of condensate from the remaining vapor, which is then separated in ossimo pipe 10. The pressure of the gases behind the expander installed in order to provide sufficient lifting the torch over the chimney to disperse emissions. For the conversion of nitric oxide into carbon dioxide before the contact-surface capacitor 70 cooled air in the heater 151 is served by the duct 179 in the pipeline 13 near the steam generator 79. Nitric oxide, acting together with the leaving gases and air in the contact surface condenser, is converted into carbon dioxide when the temperature of the mixture of gases is less than 140oWith and absorbed in the condenser. Thus, the amount of supplied air adjust knob 181 content or reducing the content of nitrogen oxide for this capacitor. For more effective cleaning of the combustion products from sulfur oxides sulfur dioxide oxidizes to sulfur at a temperature of less 450oWith nitrous water, which is supplied from the sump of the contact-surface of the condenser 70 by pump 182 to 183 water in a spray device of the pipeline 13 near the steam generator 79. Sulfur dioxide comes along with the combustion products in the condenser, it is better absorbed than sulfur, and thus more reduced the content of these oxides in unsinew content of sulphur dioxide in the gas contact surface of the capacitor 70.

With the aim of raising the pH of the condensate in the circulation circuits water coming from the hot 30 and 29 cold parts of the battery are mixed in mixers 185 and 186 (Fig.5) aqueous solution of ammonia coming from the pipes 188 and 189. When the pH of water at the faucets regulate the regulators 190 and 191 changes the amount of noise solution for pipes 188 and 189 in these mixers. Excess condensate in the cold part of the battery is drained through the pipeline 192 into the sewer, while it is neutralized in the mixer 193 the addition of an aqueous ammonia solution from the tank 187 pipeline 194. The pH of the condensate at this mixer regulate the regulator 195 above or equal to 7. The pH of the condensate to the circulation outlines of hot and cold water is determined depending on the corrosion resistance of pipelines and equipment, as well as the results of chemical analysis of the composition of the condensate. The condensate drain pipe 196 is served in the appliance recycling condensate 197 for its processing. In this setting, recover the ammonia from the solution and get semi-finished products or commercial products.
