Cassification：Economizer for Boiler

Introduction：The flue gas heat exchanger is installed at the boiler flue gas outlet. The flue gas is cooled by the heat exchange principle, and the waste heat carried by the flue gas is recovered to heat another medium such as water or oil. That is, the waste heat is recovered and the flue gas temperature is reduced. Energy is reused, which not only conforms to environmental protection and energy saving, but also maximizes the use of energy.
