The invention relates to the field of engine construction, namely, the power plants based on diesel engines for the generation of electric energy. The invention can be used to improve the efficiency of power plants by utilizing the heat of exhaust gases of a diesel engine in order to obtain from crude oil or gas condensate (hydrocarbon) fuels for diesel engines.

Known power plant in which the heat of the exhaust gas is used for heat supply of consumers. The exhaust gases are used to heat water, which plays a role of the heat carrier, which is then served to the user and transfers the received heat /Krivov Century, Sintov S. A. the efficiency of diesel installations by utilizing the exhaust heat of the engine, 1979, 10, S. 14-18/.

However, to realize the benefits of such power plants shall be in close proximity to the consumer of thermal energy.

Known SIV vapor in the evaporator, is supplied to the turbine of the turbocharger of diesel engine for performing additional work /Krivov Century, Sintov S. A. the efficiency of diesel installations by utilizing the exhaust heat of the engine,1979, 10, S. 14-18/. This allows you to increase the power turbine of the turbocharger.

However, the reserves for increasing the efficiency of the diesel engine by increasing the capacity of the turbine of the turbocharger is limited, which does not allow to significantly improve the effectiveness and efficiency of the power plant. The power plant becomes much more complicated and requires a supply water from an external source.

Closest to the claimed is power installation according to the author's certificate of the USSR 1321880, IPC F 02 G 5/02, 1985, publ. 07.07.87, bull. 25.

The power plant includes a diesel engine connected to an electric generator, a boiler with a furnace chamber, connected gazovykh pipe to the exhaust manifold of the diesel engine, the main feedwater and heat-insulating casing of the camera. Highway intake air in the diesel engine is connected to the air jacket of the combustion chamber. Each of highways made in the form of two parallel overlapping branches. In one of the branches with the connecting pipeline is served to the outlet of the register of the boiler. Register the exhaust gases are directed into the combustion chamber, in which, due to the presence of underutilized in a diesel engine the air is supplied to the combustion boiler fuel. The resulting flue gases give up their heat to the feed water. The air in the diesel comes from the atmosphere through inlet casing. In the diesel cylinder enters the heated air, which improves the combustion process and increases the exhaust gas temperature.

However, this power unit has the following disadvantages. Effective use of installation only in the immediate vicinity of thermal energy consumer. In the absence of such, the efficiency of the power plant is the same as in a diesel engine operating in its composition. However, it does not solve the problem of providing fuel power plants operating at a distance from the settlements, and the supply of fuel which is difficult.

The invention solves the problem of increasing the efficiency of the power plant, running away from consumers of thermal energy. In addition, the invention solves the problem of obtaining from hydrocarbon fuels for diesel engines when operating power plants in areas transportation diz is , coupled with an electric generator, diesel engine fuel tank, boiler, connected gazovykh pipe from the outlet of the diesel engine, the supply line to the fluid in the boiler according to the invention is equipped with a tank for hydrocarbons, which is connected to the supply line to the hydrocarbons in the waste-heat boiler, equipped with evaporative column, which is connected to the input pipe to pipe output of hydrocarbons from the recovery boiler, provided with a heat exchanger for fuel oil, the cavity for hydrocarbons which are included in the supply line to the hydrocarbons in the boiler, provided with a cooling heat exchanger, moreover, the heat exchangers its input connections connected respectively with the lower and upper output sockets evaporative columns, and is equipped with a tank for fuel oil and tank for light fuel fractions connected with the output nozzles respectively of the heat exchanger for fuel oil and the cooling heat exchanger, and the air space of the tank for light fuel fractions and tank for fuel oil pipe connected to the inlet manifold system air supply diesel.

This allows the use of quality raw materials, which when passing through the elements of the power plant is divided into fuel oil and light fuel fractions (products wide fractional composition) suitable for use as fuels in diesel engines, and enables you to submit neskondensirovannyh pair of light fuel fractions and fuel oil in the intake pipe of the power system diesel air to use these vapor as fuel for diesel engines.

The presence of tanks for hydrocarbons, light fuel fractions and fuel oil allows you to accumulate and store hydrocarbons and products of its processing. The existence of the evaporation column allows the separation of hydrocarbons on a pair of light fuel fractions and oil. In the cooling heat exchanger is the condensation of the vapor light fuel fractions. In the heat exchanger for fuel oil transfer heat from fuel oil hydrocarbon feedstock entering the boiler.

Another difference is the connection pipe of the tank for light fuel fractions from the fuel tank of a diesel power plant. This allows the use of light fuel oil as fuel for diesel engines.

Izobreteniya 3, turbocharger 4, the exhaust pipe 5, the fuel tank 6, the fuel filters coarse 7 and 8 thin cleaning, fuel pre-supply pump 9, the fuel high-pressure pump 10. Diesel engine connected to an electric generator 11. The exhaust pipe 5 of the diesel engine is connected with gazovykh pipe of the boiler 12. The flue outlet of the boiler is connected with the exhaust pipe 13. The supply line to the hydrocarbons in the HRSG includes a pump 14, a valve controlling the flow of hydrocarbons 15, the cavity for hydrocarbon heat exchanger 16 for heating oil. The pump 14 is connected by a clutch to the shaft of the motor 17. Highway hydrocarbon boiler is connected to the inlet side of the evaporation column 18. On the pipe connecting the boiler with the evaporation column, set the meter 19 temperature. The upper outlet of the evaporation column is connected to the cooling heat exchanger 20 having an air fan 21 mounted on the motor shaft 17. On the pipeline connecting the evaporating column with cooling heat exchanger, and the supply pipe of hydrocarbons in the heat exchanger 16 for fuel oil installed the nick 16 for fuel oil. The power plant also includes a tank 23 for hydrocarbons, tank 24 for fuel oil and tank 25 for light fuel fractions. Each tank has a tube 26 for controlling the liquid level in the tank. Tanks for fuel oil and light fuel fractions have drain pipes with valves 27 and 28, respectively. Tank for light fuel fractions connected with the fuel tank diesel pipe 29 with the valve 30. Airspace tank for light fuel fractions and tank for fuel oil is connected to the inlet manifold of the diesel engine by conduit 31 to the valve 32. On the drain line light fuel fractions in the tank 25 for light fuel fractions has an observation window 33.

The plant is operated as follows.

Hydrocarbons from the tank 23 by a pump 14 driven by an electric motor 17, through the valve 15 controlling the flow of hydrocarbons is fed into the cavity of hydrocarbons of the heat exchanger 16 for heating oil, where the substrate is heated by heat exchange with the hot oil. Further, the hydrocarbon raw material is fed into the boiler 12. The exhaust gases of the diesel engine 1 from the exhaust pipe 5 enter the HRSG 12, where the transmit portion of the heat hydrocarbon cerebrosidase into the atmosphere. From the recovery boiler heated hydrocarbon feedstock is fed into the evaporation column 18. Light fuel fractions into evaporative column in pairs and rise in its upper part, the payoff comes in the cooling heat exchanger 20, blown air, which is blown by the fan 21 driven by an electric motor 17. In the cooling heat exchanger is the condensation of the vapor light fuel fractions. After this liquid light fuel fractions are served in a tank 25 for light fuel fractions. The oil flows into the lower part of the evaporator of the column and enters the oil cavity of the heat exchanger 16 for heating oil, which gives off some heat cold hydrocarbon raw materials. After that, the cooled oil is discharged into the tank 24 for fuel oil. For temperature control of hydrocarbons at the inlet in the evaporating column, the vapour pressure light fuel fractions at the outlet of the evaporator of the column and the pressure of the hydrocarbons at the inlet of the heat exchanger for fuel oil provided by the meter 19 temperature and pressure gauges 22. The level control of hydrocarbons and products of its processing by using tubes 26. To monitor aggregate state light fuel inlet evaporative column at the required level for different modes of operation of the diesel is carried out by regulating the flow of hydrocarbon feed valve 15. By lowering the temperature of the exhaust gases of a diesel engine power plant below the level that provide heating of the hydrocarbon feedstock to the desired temperature, the valve 15 controlling the flow of hydrocarbons is closed.

The selection of the finished products from the tanks is carried out on the drain pipes with valves 27 to the tank 24 for fuel oil and 28 on the tank 25 for light fuel fractions.

If necessary replenishment of fuel in the fuel tank 6 of the diesel engine 1, the valve 30 is translated to the open position and light fuel fractions from the tank 25 through the pipe 29 to flow into the fuel tank 6 diesel engine that allows you to use them as fuel for diesel engines.

This allows the use of a pair of fuel oil and light fuel fractions as fuel for diesel 1 Mostovoy installation. Regulation of the flow of vapor fuel oil and light fuel fractions is carried out by the valve 32.

Air blower Yong option connection of the air cavity of the cooling heat exchanger 20 with the intake pipe 3 diesel, which can be used for cooling the heat exchanger 20, the air supplied to the diesel.

Regulation of the flow rate of the hydrocarbon feedstock can be automated by use of the control valve 15 controlling the flow of hydrocarbon raw signal from the sensor charge pressure or from the meter 19 temperature hydrocarbon inlet evaporative column.

The flow of hydrocarbons in the installation can be done by creating excess pressure in the air tank 23 for hydrocarbons, which can be used by the air injected into the diesel turbocharger 4. Summing up the air in the air space of the tank 23 for hydrocarbons, it is possible to ensure the flow of hydrocarbons in the installation without the use of a pump 14.

Hydraulic resistance encountered when the current exhaust gas in the cavities of the recovery boiler, contribute to the damping of the wave energy of the gas stream, which reduces the noise level of the exhaust of a diesel engine and allows you to refuse the use of the silencer.

The invention improves the efficiency of the power plant, running away from consumers th is anouki fuel and create fuel to enable other diesel engines in the power plant operation in areas deliveries of diesel fuel which is difficult. This increases the degree of autonomy of operation of the power plant and solved the problem of using neskondensirovannyh vapor light fuel fractions and residual fuel oil, which increases the utilization of products of processing of hydrocarbon raw materials and fire safety installation.
