The economizer is the heating surface of the boiler feed water heated into saturated water under drum pressure in the flue at the tail of the boiler, which reduces the exhaust gas temperature of the flue gas due to the heat it absorbs from the low-temperature flue gas, saves energy and improves efficiency. The economizer consists of a horizontal arrangement of parallel elbow pipes (commonly known as serpentine pipes). Boiler economizer is a device installed at the tail of the boiler for the recovery of waste heat. It is mainly suitable for industry, and in recent years, it has also been popularized in agriculture and some related industries. The economizers produced in our factory are mainly used in the boilers of large power stations.
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.
