Coal Fired Boiler Stack Economizer
Boiler Stack Economizer Working principle
Boiler economizer is kind of heat exchanger to heat the feed water using the flue gas heat. The flue gas coming from the tube outside is up and down cross-flow scrubbing the tube bundle, passing the heat to the tube wall. The water is flowing from bottom to top, and absorts the heat from the tube wall, and its temperature is getting high. This way not only can countercurrent heat transfer to save metal consumption, but also is good for water/steam to flow and exhaust as well as decreasing corrusion. One more, this way works well for dust cleaning.
Boiler Stack Economizer Details
Boiler economizer is part of the heating area of boiler, to heat the feed water into saturated water inside the flue ducting, due to its absorption of low temperature flue gas heat, the economizer reduces the exhaust temperature of flue gas, save the energy, improve the efficiency, so called as economizer. Economizer steel tube type is without pressure limit, can be used as a boiling type, generally made by the outer diameter of 32 ~ 51 mm carbon steel tube.Sometimes in tubes with fins and fin, to improve the heat transfer effect. Boiler economizer is used for recovery of waste heat from boiler.
