FIELD: machine building.
SUBSTANCE: invention relates to power plant engineering. Thermal energy from the furnace, the radiant energy of the sun, etc. They are connected to the heat exchanger and heat the air in the internal cavity of the heat exchanger. Control system monitors the air in the heat exchanger temperature and pressure values. At the time when the air in the heat exchanger temperature and pressure reaches the entered in the control system maximum air pressure and temperature limit, the control system opens the cylinder inlet valves. Maximum value of the air pressure and temperature in the heat exchanger is selected based on the strength characteristics of the heat exchanger material. Air from the heat exchanger flows through the cylinder inlet valve into the working cavity of the piston. Under the action of air, the piston starts moving from the initial point of motion to the final point of motion. Air charges the air accumulator from the compressor cavity of the piston through the non-return valve of the accumulator. Linear electric generator stator magnet magnetic flux is closing through the linear electric generator armatures. As a result of the movement of the armature of the linear electric generator, the surface area of the armature of the linear electric generator and the linear electric generator adjacent to the armature, the surface area of the stator magnet of the linear electric generator decreases. Respectively, the magnetic flux in the armature of the linear electric generator and the stator magnet of the linear electric generator varies, and in the linear electric generator coil the electric power pulse is generated. At the time of arrival of the piston at the final extreme point of motion, the control system closes the intake valve of the cylinder and opens the exhaust valve of the cylinder. Anchor of the linear electric generator is attracted to the opposite pole of the stator magnet of the linear electric generator. As a result, the piston moves to the initial position to generate the next power pulse position. Exhaust air is forced into the atmosphere from the working cavity of the piston through the open cylinder outlet valve, and through the cylinder check valve air from the atmosphere is sucked into the compressor cavity of the piston. Simultaneously, the control system opens the pneumatic accumulator valve and air from the pneumatic accumulator enters the heat exchanger, in which the next cycle of heating the air to the temperature and pressure takes place, at which the temperature and air pressure in the heat exchanger reach the limit of the maximum value of air pressure and temperature entered in the control system. After that, the cycle of generation of the electric pulse is repeated.
EFFECT: technical result consists in provision of the thermal energy into electric power conversion maximum efficiency with uneven heat supply to the heat exchanger.
