The method of operation of a gas turbine installation with a complex system of deep heat utilization and reduce harmful emissions into the atmosphere as follows. The air taken through the air intake device 9 (Fig.1) and serves on the duct 13 in the air filter 10, where it is cleaned from dust and solid particles, then through the air duct 14 and direct it to the contact water / air heat exchanger 11, in which the air is heated or cooled depending on its temperature, after which the duct 15 is served in the muffler 12 and from there via the air duct 16 to the input of the low-pressure compressor 1.

The air is compressed in the compressor 1 low and 2 high pressure and serves it in the combustion chamber 6 is TV, which is heated in regenerative toplivopotreblenie 30, and clean the fine filter 31.

Steam for heating of fuel fed into toplivopodachej 30 of the steam generator 17 to the steam line 49, and assign it to the line 58 into the power turbine, thus regulate the temperature of the liquid fuel regulator 66 below the temperature of vaporization in this toplivopotreblenie. Burned gas in the combustion chamber 6 when the air excess factor of 1.02-1.05 by a liquid when 1,05-1,10. This change control devices 72, 73 and 71 costs of air, fuel and the excess air coefficient. Lower the temperature of the gases in the combustion chamber 6 by the supply of steam from the utilization of the steam generator 17 to the steam lines 49 and 47 in the combustion zone and regulate its regulator 64 for determining the temperature of the gases in the combustion chamber. As the defining temperature adopted this temperature gases, in which complete combustion of the fuel in excess air coefficient equal to or greater than one, oxides of nitrogen and carbon within the acceptable range, no dissociation of the combustion products and installation works reliably.

Dorogaya products of incomplete combustion in the chamber, doirani is via the air duct 37, as the fuel through fuel line 36, thus regulate the amount of supplied air regulator 70 to the content or to reduce the content of carbon monoxide for this camera, and the amount of fuel - regulator 69 on the temperature of the gases in this chamber exceeding 700oC. From the combustion chamber 6 and the combustion products are directed to a high-pressure turbine 4, where they lead her into motion together with the high-pressure compressor 2. In this turbine serves more pairs for cooling gases in the steam lines 49 and 48 of the steam generator 17. The amount of steam applied to regulate the regulator 63 temperature gases, which determines the reliability of the turbine. From the high-pressure turbine 4 gases are served in a low-pressure turbine 3, where they lead her into motion, together with the low-pressure compressor 1. In this turbine serves more steam from the steam generator 17 to the steam line 46. The amount of steam applied to regulate the regulator 61 steam pressure for the steam generator 17. From the low-pressure turbine 3 through the pipeline 33 through the secondary combustion chamber 32 and the combustion products are directed to the power turbine 5, which lead her into motion together with the load 7. Here sum more steam through the steam pipe 45. The amount of steam applied regulirovki turbine 5 fail in utilizing the steam generator 17, and go in a contact condenser 18. In this steam generator, water is supplied from the hot side of the battery 38 by pump 42 through inlet water pipe 40 and the pressure water line 44. The amount of water supplied regulate the regulator 60 temperature of steam produced.

In the contact condenser 18 and the combustion products are cooled by water which is supplied from the cold side of the battery by pump 43 through inlet water pipe 41 and the pressure of the water supply system 50 of the spray device of this capacitor, with one of them secrete moisture. Divert the heated water through water pipes 51 in the hot side of the battery 38. Regulate the temperature of the gases for contact condenser 18 by the controller 67 is below the dew point temperature by changing the amount of water supplied to the condenser. The cooled gases in the contact condenser 18 further cooled in expansion screw machine 8, which transmits its power to the load 7. Forth from the products of combustion in the dryer 19 is separated moisture under the action of centrifugal forces and served in the superficial gas heat exchanger 20. Water through the heat exchanger and the cold part of the battery heat circulating through the pipes 56 and 57, while it is cooled cold productrelease water through the heat exchanger. The noise of the heated products of combustion in the gas heat exchanger 20 to reduce the silencer 21, and then the exhaust gases are removed to the atmosphere through the chimney.

The operation of the gas turbine installation with other typical circuit (Fig.2) differs significantly from the above. The air taken through the air intake device 9, is heated or cooled, cleaned and reduce its noise in complex air preparation device 82 and serves in the low-pressure compressor 1, where the air is compressed and its temperature and pressure increase. Heated air down the duct 75 in surface air cooler 74, where it is cooled by water, which is down from the cold side of the battery 39 under the action of the pump 43 through the pipes 41 and 90, and divert this water to water 91 in the hot side of the battery 38. In this case, the temperature of the cooled air support above the dew point temperature change controller 92 of the number of circulating water through the cooler. From the surface of the cooler 74 air is directed into the high-pressure compressor 2, where the air is compressed and its temperature and pressure increase, then served in a regenerative air heater 78, where it is again heated t is t and filtered in the complex fuel preparation device 83, served in the combustion chamber 6, burn likewise, when the coefficients of excess air close to the unit as described above for the schematic diagrams of Fig. 1. Dorogaya products of incomplete combustion in the mixing zone of the combustion chamber, which serves the additional air duct 37 from the high-pressure compressor 2. Thus, the amount of supplied air change controller 70 to the content or change the content of carbon monoxide for this camera. The temperature of the combustion products lower in the combustion zone of the steam flow from the utilization of the steam generator 17 to the steam line 47 in the duct 80 before the combustion chamber 6. Regulate its regulator 64 similar to that described when considering the scheme in Fig.1.

Further, the combustion products down in a high-pressure turbine 4, where they are expanding, bring it in motion, and with it the high-pressure compressor 2. To reduce the gas temperature before the turbine feed steam from the steam generator 17 to the steam pipe 48 into the pipeline 81. The temperature of gases in a gas turbine regulate the regulator 63 similar to that described when considering the scheme in Fig. 1. In the pipeline 77 connecting the turbine to the high pressure and low pressure, serves except potoski 83 when the valve is open 87 and 88 closed and excess steam from the steam generator 17 to the steam line 46 when the excess pressure. These pairs, mixing with the gases come in a low-pressure turbine 3 and there do more work together with gases. Produced power low-pressure turbine 3 are passed to the low-pressure compressor 1 and the load 7. The products of combustion from the turbine is directed to a regenerative air heater 78 together with the steam through the duct 33, which is supplied when the valve 88 open and closed 87. This heater they cool the air and then served in the utilization of the steam generator 17 to produce steam. The water in the steam generator fail, and the temperature of steam produced regulate similarly, as described in the diagram (Fig.1).

The cooled combustion products are then sequentially cooled first in the contact condenser 18 below the dew point temperature, and then screw in the expansion machine 8 to the freezing temperature of the condensate. Here the gases expanding, perform the work, which is passed to the generator 89 to convert into electricity. After expansion screw machine 8 from the flue gas is separated moisture, heat and reduce the generated noise in complex gas treatment device 84, and then removed into the atmosphere through the water is si, and the rise of the plume above the pipe is insufficient to dispel the flue gases, it serves the air after a high-pressure compressor 2 via the air duct 93 in the pipeline 29, thus regulate the amount of supplied air regulator 94 on the temperature of the gases at the mouth of the chimney, above the dew point.

Further variants of the method of operation of a gas turbine installation with the same typical circuit of a gas turbine engine in which the air between the compressor is cooled and humidified in the contact cooler 95 (Fig. 3) water, which is supplied from the cold side of the battery 39 by pump 43 through the pipes 41 and 103, and unloaded it from the tray via the air duct 105 in the hot side of the battery 38. Thus regulate the temperature of the air behind the cooler above the dew point temperature by changing the amount of water supplied by the controller 107. To reduce the work of compression of the compressor, high pressure, and increase the humidity of the air before the combustion chamber, it is cooled and humidified in the contact cooler 96 water, which is supplied from the cold side of the battery 39 by pump 43 through the pipes 41 and 104 in a circular saw trimming device of this cooler, and videogo air before the combustion chamber 6 above the dew point temperature by changing the amount of water supplied by the controller 108 in the cooler.

In cases when this scheme is also provided by the combustion of fuel at the coefficients of excess air close to the unit as and when considering the options in the previous schemes (Fig.1 and 2). Dorogaya products of combustion in the secondary combustion chamber 32 between turbines 4 high and low 3 pressure. The air system is supplied from the high-pressure compressor 2 via the air duct 102. The quantity of supplied air change controller 70 to the content or change the content of carbon monoxide for this camera. To increase the pressure of the exhaust gases prior to contact with the capacitor 18 without reducing the power of the low-pressure turbine increase its screw injection machine 97, which is lead by an electric motor 98. For contact condenser energy of the combustion products in turn work coil expansion machine 8, which is passed to the generator 89 to generate electricity. By increasing the gas pressure in the contact condenser to reduce its size and weight, increase the absorption of harmful substances by condensation and increase the temperature of condensation of water vapor. Water in contact condenser is supplied from the cold side of the battery 39 by pump 43 through the pipes 41 and 50, and from the contact condenser 18 above the dew point temperature, and for desiccant 19 is above the freezing temperature of the condensate changes the amount of water supplied by the controller 67.
