The principle of boiler economizer is to lower the exhaust gas temperature (du exhaust gas temperature is mandatory in the country); The heat replaced by the boiler economizer returns to the boiler, which is equivalent to increasing the boiler feed water temperature. When the boiler output is certain, the energy consumption is reduced.

When used as an economizer of flue gas and water heat exchange boiler, the purpose of the boiler economizer is to recover the waste heat of flue gas. Boiler energy-saving devices are classified according to their specific uses and exchange media. They are mainly divided into boiler energy-saving devices for flue gas liquid waste heat recovery and boiler energy-saving devices for flue gas air heat exchange. The materials used are generally all stainless steel 304 frames and stainless steel spiral fin tubes. It has the following characteristics: fast heat transfer, energy-saving, beautiful, durable, etc.
