With the adjustment of energy structure in the world, natural gas-fired equipment is used more and more popularly. However, the temperature of wet flue gas from all natural gas-fired equipment used at present is too high. These cause the consumption of high-quality energy and environmental pollution. The anticorrosive condensing heat exchanger is installed in the natural gas-fired equipment to recover and apply effectively waste heat of flue gas and a great deal of water vapour potential heat, and thus improve the heat efficiency. This paper analysed the feasibility and economy of the central and local boiler house installed the wet flue gas condensing heat exchanger.
