The HDB Class A Industrial Boiler Spiral Fin Tube Economizer is a heat exchanger used to capture the "lost or waste heat" of boiler hot chimney gases. The economizer can be arranged in two ways: perpendicular or parallel to the front wall of the boiler in the direction of water flow. Large boilers often use suspended economizers. Inexpensive and fine spiral-finned tube economizers typically transfer waste heat to boiler feed or return circuits, but can also be used to heat domestic water or other process fluids.
1. Fuel saving: the economizers are placed at the rear part of boilers. This way can decrease the smoke and gas temperatures, thus to save fuels.
2.Improve the working conditions of steam drums: due to economizers, the feed water temperature is increased when entering the steam drum. It reduces the temperature difference between the feed water and steam drum wall as well as steam drum thermal stress, so that it improve the working conditions of steam drums and increase the service life.
3.Reduce the boiler manufacturing cost: for the feed water is heated in the boiler economizers. The use of low temperature spare parts as boiler economizers to replace some of high-priced high temperature water wall panels reduces the cost to manufacture boilers.
