CRYOGENIC GAS-STEAM PISTON POWER PLANT, GAS-STEAM UNIT, INTERNAL COMBUSTION PISTON CYLINDER ON NATURAL GAS AND OXYGEN, GAS-VAPOR PISTON CYLINDER AND LINEAR SYNCHRONOUS ELECTRIC MACHINE

摘要

FIELD: machine building.;SUBSTANCE: invention relates to power engineering and specifically to thermal power plants. Cryogenic gas-steam piston power plant consists of air cleaning device (1) connected to air compressor (2) and cooler (3) connected to expander (4). Also consists of cryogenic tank (8), evaporator (10) of liquid gas and pneumatic motor (11) connected to generator, stack (14), decarbonator – mechanical filter (20) of water, deaerator (21), pumps (22) of injection water and circulating pumps. At that, power plant includes nitrogen fraction condenser (5) connected to rectification column (6), which supplies cryogenic pipelines of liquid oxygen and nitrogen to separate cryogenic reservoirs (7, 8) for temporary storage. Oxygen reservoir (7) is connected to piston-type gas-steam unit, into which liquid oxygen is supplied by means of cryogenic pump (9) for natural gas combustion. Air compressor (2) and expander (4) are free-piston machines mechanically connected to linear synchronous electric machines. Also disclosed are a piston-type gas-steam unit of a power plant, an internal combustion cylinder, a gas-steam cylinder and a linear synchronous electric machine.;EFFECT: technical result consists in improvement of efficiency of power plant due to higher degree of compression and degree of utilization of heat of exhaust gases, reduced energy consumption for compression and gas pumping.;5 cl, 16 dwg
