Steel Boiler Economizer Heat Exchanger Tubes For Industrail Power
Plant,ISO/ASME Certificate,High Efficient
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.
