Research on Boiler Flue Gas Heat Recovery with Fluoroplastic Heat Exchangers

Abstract

Abstract:A fluoroplastic heat exchanger is significant for recovery of boiler flue gas heat. Equipped with a W-type heat exchanger which is mainly made of fluoroplastics, the waster heat recovery system designed herein can be used to recover the heat of low-temperature flue gases from coal-fired boilers; through calculation, finds that the design coefficient of heat transfer is consistent with the coefficient of ICEM and Fluent simulation; accordingly, a heat exchanger is designed and related parameters are calculated. The self-designed recovery system provides a great reference value for China to recover waste heat of flue gases from industrial boilers.
