6 Ton Finned Tube Economizer Square Cast Iron Biomass Boiler Economizer

6ton Biomass Boiler Economizer finned tube economizer China manufacturer

Boiler square cast iron economizer Characteristics:

1. Absorb the heat of low-temperature flue gas, reduce the exhaust gas temperature, reduce smoke loss and save fuel.

2. Since the feed water is heated in the economizer before entering the steam drum, the heat absorption of the feed water on the heated surface is reduced, and the economizer can be used to replace the partially evaporated evaporating heating surface.

3. The temperature of the feed water is increased. When entering the steam drum, the wall temperature difference is reduced, the thermal stress is reduced accordingly, and the service life of the steam drum is prolonged.

Other features

1.The economizer in boiler is a device installed in the lower part of the flue of the boiler to recover the waste heat of the exhausted smoke, and the boiler feed water is heated to the heated surface of the saturated water under the steam drum pressure, because it absorbs the heat of the high temperature flue gas, and reduces The exhaust gas temperature of the flue gas saves energy and improves efficiency, so it is called an economizer.

2.Steel tube type economizer in boiler is not limited by pressure, can be used as a boiling type, generally made of carbon steel pipe with an outer diameter of 32~51 mm.

3.sometimes add fins and ribs outside the tube to improve heat transfer.

4. Economizer in boiler are mainly used in industry, and are gradually popularized in agriculture and some related industries.
