Finned Tube Flue Gas Heater

Since the flue gas after wet deacidification contains a lot of water vapor, it will cause water accumulation in the induced draft fan after passing through the induced draft fan, and form white smoke after passing through the chimney, causing serious pollution to the surrounding environment. In order to solve the problem of white smoke, a flue gas heater is installed after wet deacidification, and the flue gas at about 60 °C after deacidification is heated to about 130 °C by steam, which solves the effect of water vapor in the flue gas on the induced draft fan and chimney. Corrosion and white smoke from the chimney. Finned tube type flue gas heater, low temperature flue gas shell side, the two media do not contact each other in the steam tube, and the finned tube is used for heat transfer. The heat exchange area on the gas side increases the heat transfer coefficient, which can reduce the overall volume of the equipment. Features: (1) The fluid resistance is small, the heat exchange efficiency is high, and the steam consumption is reduced. (2) The equipment has compact structure, corrosion resistance and long service life.
