SA192 Base Tube Made Boiler Economizers for Sugar Mill

Product Details

Boiler economizer is the rear heating surface of the boiler, which is usually located at the outlet of the boiler. The economizer collects heat from the flue and increases the inlet temperature of the boiler through the waste heat of the flue gas. While reducing the exhaust temperature, it increases the inlet temperature of the boiler, reduces the thermal stress caused by the temperature difference between the drum wall and the feed water, and reduces the shrinkage and expansion of the drum. The economizer of our company generally adopts 20 medium and low pressure boiler tubes, 20g seamless steel tubes or ASME grade steel tubes. It reduces the temperature of flue gas, recovers heat to the maximum extent, and improves the overall efficiency of the boiler, so as to help customers reduce fuel consumption and reduce the cost of the boiler.

Functions of Boiler Economizer
We can summerize the functions of economizers as below:
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.
