COMPLEX THERMOELECTRIC CROWN FOR CHIMNEY Russian patent published in 2020 - IPC F23J15/08 

FIELD: heat exchange.

SUBSTANCE: invention relates to heat engineering. Integrated thermoelectric crown for a stack, comprising a cylindrical housing made of a corrosion-resistant material with high heat conductivity, which is divided by an external support ring onto an upper corrugated working part, resting on the end of the stack, and lower support part, passed inside chimney, corrugations of working part of housing form rectangular sockets, in which are partially recessed thermoelectric links, consisting of rectangular inserts, inside which rows are placed, consisting of arranged in parallel thermoelectric converters, in each of thermoelectric converters pair of wire pieces of metals M1, M2 are parallel with formation of a certain gap between, thermoelectric links are installed in sockets so that large part of each thermoelectric converter of each row is washed by external air, connected thermoelectric links of the crown are connected in pairs to each other, forming thermoelectric unit, which is connected to terminals. Case is conical-cylindrical with upper conical working part with upper diameter, which closes from above cold part of external surface of pipe, with angle of inclination greater than or equal to angle of natural slope of water, wherein with joint of working and support parts inside housing annular inclined bead is connected, forming annular drain tray, equipped with drain pipe with locking device connected to drain pipeline and condensate tank, working part of housing is made with inclined corrugations forming inclined seats, outer surface of working part of housing between thermoelectric links is covered with layer of heat insulation, lower than height of thermoelectric converters, each thermoelectric link at the top and bottom of the working part of the housing is connected by bridges to collectors of similar electric charges, forming a thermoelectric unit, and the above headers are connected to the terminals.

EFFECT: technical result is higher environmental safety and efficiency of complex thermoelectric crown for chimney stack.
