Waste gas heat recovery unit (industrial use)

The waste heat exchanger is designed to cool flue gases, hot air of furnaces to the lowest possible temperatures and transfer heat to another heat carrier, as a rule, water, for heating for the needs of hot water supply, heating, ventilation.

Waste heat exchangers or recuperators have been developed in which heat is exchanged between two gas streams. Structurally, a waste heat exchanger or cooler of flue gases consists of a heat exchange surface formed by corrugated steel sheets welded in pairs, forming two channels. One channel is for flue gases, the other is for the heated heating medium. Finned heat-resistant tubes can also be used as a heat exchange surface.

Cooling of flue gases can be carried out as standard from 250-280 ° C to 130-150 ° C. If the task is deeper cooling, then cooling is possible up to 50-55 ° C.

The main tasks that the installation of a flue gas heat exchanger solves:

• - increasing the degree of heat use at the enterprise;
• - saving fuel, which was used earlier to generate heat, which was uselessly emitted into the atmosphere;
• - reduction of thermal pollution of the environment;
• - creation of a more comfortable stay for personnel due to heating of industrial premises, availability of hot water for shower nets;
• - reducing the cost of production and increasing competitiveness.
