    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
