METHOD TO CONVERT THERMAL ENERGY OF SUN AND/OR BIOGAS INTO ELECTRIC ENERGY Russian patent published in 2012 - IPC F24J2/42 

FIELD: power engineering.

SUBSTANCE: there is a method proposed for direct conversion of thermal energy of solar radiation and/or burnt biogas into electric energy in a barogalvanic electric generator with electric regeneration of working substance, comprising a current-generating cell, a compressor cell and a regenerative heat exchanger, which form a closed tight circuit, which includes the following: supply of thermal energy of solar radiation and/or burnt biogas to a current-generating cell, ionisation and recombination of working substance at the borders of electrolyte and gas-permeable electrodes in cavities of high and low pressures of the current-generating cell with it producing power; isobaric cooling of working substance low-pressure steam in the regenerative heat exchanger; compression of working substance low pressure steam in the compression cell due to a part of electric energy produced by the current-generating cell, accompanied by removal of heat from it, which is used for heat supply of a low-rise building, ionisation and recombination of working substance at the borders of electrolyte and gas-permeable electrodes in cavities of high and low pressures of the compressor cell; isobaric heating of high pressure working substance in the regenerative heat exchanger and its arrival into the high-pressure cavity of the current-generating cell, at the same time in high-pressure cavities of both cells and the regenerative heat exchanger a working substance is used in liquid phase, for instance, liquid iodine, and the working substance in liquid phase in the high-pressure cavity of the current-generating cell is brought to overheated condition, for instance, to overheated liquid iodine.

EFFECT: higher efficiency of direct conversion of recovered thermal energy into electricity, simplified supply of thermal energy to a current-generating cell and removal of heat from a compressor cell and intensification of heat exchange process in a regenerative heat exchanger.
