1. , the invention provides a kind of double-fluid steam type double power generation arrangement, particularly suitable steam-type steam turbine generator, more suitable steam-type power plant and other device of steam-type;

  • The two-fluid of double-fluid steam type double power generation arrangement is water and low-boiling point liquid (ammoniacal liquor, inorganic compound, organic compound, halogen-carbon compound, hydrocarbon etc.), and the two-fluid that the present invention adopts is water and ammoniacal liquor;

    Double-fluid steam type double power generation arrangement is on the basis of steam-type fuel power station, increases by one road ammonia steam electric power;

    The fuel of steam-type fuel power station is emitted heat energy in boiler 1 burning, and 1 li water of boiler is heated into water vapor, and the water vapor superheater of flowing through is heated into high-temperature high-pressure steam;

    High-temperature high-pressure steam enters steam turbine 3, and pushing turbine 3 rotations drive the generator rotation and send electric energy;

    High-temperature high-pressure steam is discharged low temperature and low pressure water vapor and is condensed into water at vapour condenser 4 after steam turbine 3 actings, and under feed water pump 5 effects, water enters recirculation;

    Double-fluid steam type double power generation arrangement is that the high-temperature high-pressure steam of steam-type fuel power station is after steam turbine 3 acting, discharge low temperature and low pressure water vapor in vapour condenser 4 ammoniacal liquor condensation, be that ammoniacal liquor and low temperature and low pressure water vapor are carried out heat exchange, make low temperature and low pressure water vapor be condensed into water;

    Ammoniacal liquor absorbs the heat ammonification steam of low temperature and low pressure water vapor, ammonia steam flows to 6 li of the ammonia heat absorbers in boiler smoke road 2 through seamless steel pipe, ammonia steam is at 6 li heats that absorb hot flue gas of ammonia heat absorber, become High Temperature High Pressure ammonia steam, High Temperature High Pressure ammonia steam enters ammonia steam turbine 7, promote 7 rotations of ammonia steam turbine, drive the generator rotation and send electric energy;

    High Temperature High Pressure ammonia steam is discharged low-temp low-pressure ammonia steam and is condensed into ammoniacal liquor at ammonia vapour condenser 8 after 7 acting of ammonia steam turbine, and ammoniacal liquor enters recirculation under the effect of ammoniacal liquor pump 9;

    The High Temperature High Pressure ammonia steam of double-fluid steam type double power generation arrangement is after 7 actings of ammonia steam turbine, discharge low-temp low-pressure ammonia steam in 8 li in ammonia vapour condenser, use the low pressure refrigerant condenses, promptly low pressure refrigerant liquid and low-temp low-pressure ammonia steam carry out heat exchange, make low-temp low-pressure ammonia vapor condensation become ammoniacal liquor;

    Low pressure refrigerant liquid absorbs low-temp low-pressure ammonia steam heat and becomes refrigerant vapour, refrigerant vapour is piston compressor 10 suctions of power by steam, be discharged to 11 li of condensers after compression, at this moment its pressure and temperature raises, the refrigerant vapour that pressure and temperature is higher, carry out heat exchange 11 li of condensers with the cooling water that continued to flow, be condensed into the elevated pressures refrigerant liquid, reduction valve 12 decompression of flowing through of elevated pressures refrigerant liquid becomes low pressure refrigerant liquid, and low pressure refrigerant liquid flows to 8 li in ammonia vapour condenser, absorb low-temp low-pressure ammonia steam heat, continue recirculation, refrigerant liquid is an ammoniacal liquor, and cooling water is boiler feed water;

    Feedwater flows to 11 li of condensers under the effect of feed water pump 5, the heat of absorption refrigeration agent steam becomes the heat feedwater, and the heat feedwater flows to boiler, continues recirculation, 3 ℃

    -5 ℃

    of feed temperatures.
