FIELD: hot gas positive-displacement engine plants.
SUBSTANCE: one or several sections of the heat accumulator are charged repeatedly depending on the operation conditions of the Stirling engine (duration of continuous operation, required power, and so on). For this purpose, the heat accumulator is divided into sections. The sections are charged by energy supplied through the heating devices to the heat accumulating agent. After charging, when the engine is operated in autonomous regime, the heat released by heat accumulating agent through the accumulator walls is transmitted to the walls of the heater of the Stirling engine to provide its starting and operation. When the Stirling engine is in operation, mechanical energy is converted into the electric power with the use of the electric generator. To cool the Stirling engine, a refrigerator is use through which the cooling agent is supplied.
EFFECT: enhanced reliability and simplified structure.
