TPP FLUE GASES HEAT AND CONDENSATE UTILIZER Russian patent published in 2017 - IPC F22B1/18 

FIELD: energy.

SUBSTANCE: invention relates to industrial heat power engineering and can be used in TPP boiling rooms, operating on high humidity solid fuels. Utilizer of heat and condensate of TPP flue gases comprises heat exchanger in form of reservoir, filled with running water, inside of which parallel rows of horizontal tubes are arranged for flue gases movement along them in one direction, connected with jackets, arranged on reservoir end sides, each of which is divided by horizontal flanges into sections, wherein one jacket section upper part is connected with jacket section lower part by pipes, located on reservoir opposite. Utilizer also has gas ducts, smoke exhauster, condensate collector and pipelines. According to invention for tail flue gases temperature control utilizer is equipped with additional second heat exchanger, identical to first one, which reservoirs are interconnected via feeder, wherein output of cooled down, dried flue gases of first heat exchanger from jacket upper section through outlet branch pipe by gas duct is connected to second heat exchanger jacket lower section, and second heat exchanger jacket upper section is connected to stack by gas duct.

EFFECT: technical effect of invention consists in improvement of TPP economic performance and increasing of operation efficiency due to increase efficiency of using recovered "hidden" fuel moisture steam generation heat.
