power plant economizer,
economizer for boiler
Red Color High Efficient Fin And Tube Heat Exchanger With Long Service Life
Boiler economizers are heat exchange devices with finned tubes that heat a liquid, sometimes water, up to however sometimes doesn't exceed the boiling purpose of liquid.
We can manufacture types of boiler economizer, bare tube economizer, H finned tube economizer and spiral finned tube economizer and gilled tube economizer.
1. absorb the heat of low-temperature flue gas, reduce the smoke temperature, reduce smoke loss, save fuel.
2. Since the feed water is heated in the economizer before entering the drum, the heat absorption of the feed water on the heating surface is reduced, and the economizer can be used to replace the evaporation heating surface with high cost.
3.feed water temperature increased, into the drum will reduce the wall temperature difference, thermal stress reduced accordingly, extend the drum service life.

The boiler economizer acts as a waste heat recovery device, ensuring that this heat does not go unused.
Instead, the heat is used to essentially preheat the water, so that less heat is required to bring the water to a temperature high enough to make steam
(1) the economizer is a heat exchanger that USES waste heat from boiler smoke exhaust to heat water supply;
(2) the economizer absorbs waste heat of exhaust smoke, reduces the exhaust temperature and improves the efficiency of the boiler;
(3) due to the water supply entering the drum, the water temperature has been raised through the economizer, and the thermal stress on the wall of the drum caused by temperature difference has been reduced, thus improving the working conditions of the drum and extending the service life of the drum.
