How to effectively deal with the problem of boiler economizer?

The economizer of the boiler is generally arranged in the tail flue, and the flue gas temperature is low. When the industrial boiler is started or operated under low working conditions, it is easy to cause the flue gas temperature to be low, thus causing low-temperature corrosion of the tail heating surface. How to deal with this problem effectively, Jiangsu Sifang boiler suggests:

Control the exhaust gas temperature to meet the requirements of flue gas deacidification treatment; Adjust the feed water temperature of the economizer to change the heat absorbed by the heat absorption surface of the economizer, so as to achieve the purpose of adjusting the exhaust gas temperature. In order to enable the economizer to operate for a long time, reduce corrosion leakage and facilitate maintenance, the economizer generally adopts a vertical structure. The heating surface tube is arranged in a serpentine tube structure, and the tube row spacing is as large as possible within the allowable range to reduce the ash deposition of the tubes. The relatively thick tube material is selected in terms of material to reduce wear and corrosion.
