SYSTEMS OF INDEPENDENT ELECTRIC SUPPLY FOR UNITS OF THERMAL POWER PLANT Russian patent published in 2017 - IPC F24D3/00 H01L35/28 

FIELD: electricity.

SUBSTANCE: invention relates to heat-power engineering and is designed to provide electrical power for automation devices and actuators. Essence of the invention is as follows: the inventive system includes a high temperature and low temperature heat sources, the heat sink into external environment, an automation unit, high-temperature and low-temperature thermoelectric converters (TEC), hot junctions of which are made in thermal contact with high temperature and low temperature heat sources respectively, and the cold junctions - in thermal contact with external environment. Electrical outputs of thermoelectric converters are connected via the switchboard to the input of one or more electric batteries. The thermoelectric converter between the heat source and the block of thermocouples the mediator with damping elements at the point of contact with heat source can be added, and an exchangeable 3D-adapter for accurate geometric alignment of surfaces of the heat source unit and thermocouples. The mediator in the thermoelectric converter can be made of metal or ceramics. The damping elements can be the technical porous sheet rubber.

EFFECT: invention enables increasing the total electric power of TEC without dismantling the boiler, piping and / or its components and uninterrupted power supply of units and automation systems of the boiler.
