OPTIMAL AND EFFICIENT METHODS OF GENERATING VARIOUS TYPES OF ENERGY IN ORDER TO REDUCE THEIR COST, INCREASE RELIABILITY AND SAFETY USING STIRLING ENGINE Russian patent published in 2024 - IPC F02G5/00 

FIELD: machine building.

SUBSTANCE: disclosed is a method of using a Stirling engine (SE) to generate mechanical and electrical energy at nuclear power plants (NPP) and nuclear power units. Stirling engine connected to electric generator is installed by heater inside nuclear reactor to take up heat directly from fuel elements. Tubes of the heater and cooler of the SE have a twisted shape. For cooling of SE and generator auxiliary SE operating in mode of refrigerating machine (SrE) is used. Starting device (SD) for the SE is a generator operating in motor mode when voltage is applied to it. Standby units are universal DS (SuE), having their own combustion chamber, operating on liquid or gaseous fuel, and simultaneously capable of operating due to reception of heat supplied from a third-party source (SuE). As backup generators for initial start-up of power plant or in case of its shutdown due to accident, as well as for reactor cooling system, SE-SuE-generator units are used.

EFFECT: disclosed are optimal and efficient methods of generating various types of energy in order to reduce their cost, increase reliability and safety using a Stirling engine.
