    ASME SA210M-A1 Weighing 25 Tons Boiler Economizer For Power Plant


    ASME Standard Boiler Economizer Made of SA210M-A1 total weighing 25 tons

    Description


    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.


    Functions

    The origin to use economizers is to heat the feed water using flue gas waster heat so as to decrease the exhaust temperature and increase boiler efficiency, save fuel consumption, which is how economizer is named. If use boiler economizers, the feed water is already heated here before coming to evaporation heating surface, thus the heat absorted on evaporation heating surface as well as the heating area is definitely decreased. Boiler economizers are countercurrent placed. The working fluid average temperature is lower than that of surnatured water, and apply mandatory flow to create conditions for application of thin wall and small diameter tubes. The whole structure is also very tight. Thus, the heat transfer temperature difference and heat transfer co-efficient is higher than that of convection evaporation tube bundle who has the same smoke temperature range. That boiler economizers to replace convection evaporation tube bundles can decrease metal consumption by a large extend. Further more, the heated feed water comes to steam drum, this way can decrease the temperature difference between the water and the steam drum wall, and ultimately decrease the thermal stress of the steam drum. Due to reasons above, now economizer are the crutial parts of boilers.
