The technical field to which the invention relates.

The invention relates to energy, and can be used in the design, manufacture and operation of various thermal power plants and boiler units.

The level of technology

Analogue of the invention may be a unit for burning fuel, described as the source: Styrikovich M.A., Katkovsky CA, Serov, H.E., Boiler units, M-L., 1959. The unit contains a container of fuel, the combustion chamber and flues, which are placed in the heating surface receiving the heat of the combustion products (superheater, the economizer, air heater).

Disadvantages similar to the following: the unit is not a heat exchanger of the litter and has a high cost of production of heat.

The prototype of the invention is the plant that contains the unit for combustion of the fuel tank with fuel, the fuel line into the combustion chamber, valves, nozzles, combustion chamber, a steam turbine. Energy of the USSR in the years 1971-1975, M., 1972. These characteristics of the prototype is similar to the characteristics of the claimed invention.

The disadvantages of the prototype the following: power is not a waste litter and has a high cost of production of electricity and heat.

Disclosure of inventions

The objective of the invention is to increase eff is aktivnosti work thermal power plant.

Thermal power plant produces electric energy resulting from the conversion of thermal energy released during the combustion of organic substances, in particular fossil fuels. Among thermal power plants is dominated by thermal steam-turbine power plant, where thermal energy is used in the steam generator boiler (boiler plant) to produce steam of high pressure, resulting in a rotation of the rotor of a steam turbine connected to the rotor of the electric generator (usually synchronous generator). As fuel in thermal power plants can use, in particular, fuel oil, natural gas, lignite, peat, shale, litter and other

The boiler unit thermal power plant is structurally integrated into a whole set of devices for heat: steam to rotate a steam turbine, hot water for submission to the house by burning combustible substances, including oil, coal, peat, dung.

Technical results are:

reducing the cost of electricity and heat production;

disposal of litter;

the destruction of harmful bacteria in the litter.

All technical results are achieved due to the fact that thermal power plant comprises a unit for combustion of the fuel tank t is Pliva, the fuel line into the combustion chamber, valves, nozzles, combustion chamber, a steam turbine, and further comprises a container of litter that is connected via a pipe through the valve with a pipe feeding fuel into the combustion chamber.

The invention differs from the prototype the following characteristics: "further comprises a container of litter that is connected via a pipe through the valve with a pipe feeding fuel into the combustion chamber".

Reducing the cost of production of electricity and heat is achieved by the joint use as fuel, for example, oil and litter. Since 2004, the Russian Federation introduced fines for release into the environment of the litter. The amount of the fine from 500 to 750 rubles per ton. The house of medium size produces daily about 100 tons of litter. Then have to pay a fine of 50,000 rubles per day. In such conditions, litter for power plants can be delivered for free.

Experiments have shown that mixing of the fuel mixture, containing 20% of litter and 80% fuel oil fuel efficiency remains practically unchanged. Thus, the cost of such fuel is 20% lower fuel consisting only of oil. By reducing the cost of fuel will decrease the price of electricity and heat generated by a thermal power plant.

When burning dung happens is its utilization. Turning litter into heat. Combustion securely destroys harmful bacteria in the litter.

Brief description of drawing

The drawing shows a thermal power plant with capacities fuel oil and litter.

The implementation of the invention

The drawing shows one of the possible embodiments of the invention. Thermal power plant consists of: 1 - drum; 2 - superheater; 3 - combustion chamber; 4 - screen; 5 - burner; 6 - pod; 7 - heater; 8 - water economizer; 9 - convective superheater; 10 - line feed of the mixture of fuel with litter; 11 - tank with fuel, 12 - containers litter; 13 and 14 - cranes; 15 - mixing chamber; a 16 - turbine; 17 - generator.

The device operates as follows. Fuels, in particular oil (or crushed coal) and litter (e.g., chicken) from tanks 11 and 12 through the open valves 13 and 14 are received in the mixing chamber 15 (the camera is mounted stirrer in the form of blades), and then into the burner. In the combustion chamber of the boiler unit occur the combustion of fuel and litter, partially cooled products of combustion in the radiant heat exchange between the heated gases and covering the walls of the furnace tubes, which circulates cooling their environment (water or steam). The system of pipes called the furnace waterwalls. The output of the top and gases have a temperature of approximately 1000° C. Next, the gas passes through the convection superheater 9, in which water is converted into superheated steam, the steam then through the pipe 18 is fed to the turbine blades 16. Turbine 16 with its rotor connected to the rotor of the generator 17. The generator produces electrical energy. After convective superheater gas pass through the economizer 8, and further, the heater, in which the gases are cooled to 130-170°s and then released into the atmosphere.

Conducted by the author of the invention, experiments have shown that the combustion efficiency (the released heat) litter lower than fuel oil or coal. However, by mixing, for example, fuel oil (80%) litter (20%) combustion efficiency resulting mixture of oil and litter (the released heat) is almost equal to the emitted heat by burning the same fuel.

The experiment was conducted by heating water on the stove with the use of different types of fuel blends of the same mass.

Increase the percentage of litter in the mixture is higher than 20% may result in lower combustion efficiency.

The construction of thermal power plant according to this invention will solve the current problem of disposal of litter. Consumers will decrease the cost of electricity and heat due to the fact that litter is several times lower than the oil. At the present time for power plants litter poultry farms can be delivered free of charge. This is due to huge fines for the discharge of litter in the environment. Per tonne of discarded litter - a fine from 500 to 750 rubles (depending on the location of poultry farms). The average house produces up to 100 tons of litter per day. Benefit poultry from free recycling litter clear.

Thus, the claimed technical result is achieved.

Thermal power plant containing the unit for combustion of the fuel tank with fuel, the fuel line into the combustion chamber, valves, nozzles, combustion chamber, a steam turbine, characterized in that it further comprises a container of litter that is connected via a pipe through the valve with a pipe feeding fuel into the combustion chamber.
