THERMOELECTRIC RIM FOR STACK Russian patent published in 2016 - IPC F23J15/08 

FIELD: heat-and-power engineering.

SUBSTANCE: invention relates to heat engineering and can be used in designs of a head of stacks for recycling stack effluent heat of boiler units, industrial furnaces while their emission into atmosphere to produce electricity. Thermoelectric rim for a stack comprises a cylindrical housing, made of corrosion-resistant material with high heat conductivity, divided by the external support ring into an upper working part and a lower support part, passed inside the stack, working part of the housing has vertical corrugations which form vertical rectangular seats, in which thermoelectric elements are partially recessed, and consist of rectangular inserts made of resilient dielectric corrosion-resistant material, inside of which there are rows of parallel thermal emission converters, each of which is a pair of parallel wire lengths made from different metals M1 and M2 soldered on the ends of each other to form a certain gap with width Δ, thermoelectric elements at the top of the housing of the thermoelectric rim are interconnected in pairs by bridges, at the bottom - by electric capacitors, to form thermoelectric sections, which in turn, are connected in series to form an open ring, first and latter capacitors of which are connected with terminals.

EFFECT: recycling stack effluent heat.
