COMPLEX WASTE HEAT RECOVERY UNIT Russian patent published in 2014 - IPC F22B1/18 

FIELD: heating.

SUBSTANCE: invention relates to heat-and-power engineering and can be used for flue gas heat recovery at boilers, industrial furnaces, gas vents at air heating combined with electric power production. Proposed unit comprises body equipped with gas and air pipes. It accommodates the stack of perforated plates that make gas and air channels there between. Note here that plate perforation is composed of horizontal staggered slots. Said slots house thermoelectric units consisting of oval inserts made of resilient dielectric rustproof material. Zigzag-like rows of thermal emission converters are fitted in said slots. Every said converter is composed by a pair of bared wire lengths made from different metals M1 and M2 with their ends soldered together. Note here that said zigzag-like rows are interconnected in series by conductors to make thermoelectric sections connected with commutators of electric charges and terminals.

EFFECT: higher reliability and efficiency.
