Boiler Fin Tube H Type Finned Tube Spiral Fin Tube Used for Power Industrial Heat Exchange
Product Description
Economizer is a mechanical device intended to reduce energy consumption, or to perform another useful function like preheating a fluid. The economizer is used for other purposes as well boiler, power plant, and heating, ventilating, and air-condition in(HVAC) uses are discussed in this article. In simple terms, an economizer is a heat exchanger.

The finned tube economizer is a heat exchange element.In order to improve the heat transfer efficiency, the surface area (or inner surface area) of the heat exchanger is usually increased by adding fins on the surface of the heat transfer tube, thus achieving the purpose of improving the heat transfer efficiency.In the same heating transfer,metal consumption and ventilation energy consumption,the heating surface of fin tube economizer was reduced by nearly half compared with the bare tube economizer.It is more popular in users.
