  • What are the usual types of boiler economizers?

    Apr 13, 2021 · Apr 13, 2021 · What are the usual types of boiler economizers? Kefid. According to the degree of heating of the feed water in the economizer, the economizer can be divided into two types: boiling type and non-boiling type. If the water in the economizer is heated to a boiling state and some steam is generated, this economizer is called a boiling economizer.Learn More

  • What is the purpose of the economiser in a power plant

    The economizer is a heat exchanger, which uses the heat of the flue gases to preheat the feed water coming from the BFP, increasing efficiency of the boiler by absorbing the heat from the flue gases otherwise it would be released and wasted into tLearn More

  • How to Calculate Boiler Economizer Efficiency

    A generally accepted "rule of thumb" is that about 5% of boiler input capacity can be recovered with a properly sized economizer. A higher percentage can be recovered with a Flue Gas Condenser, assuming there is enough cold water to condense all of the flue gas that is available. The calculations to determine the efficiency of condensing economizers are complex.Learn More
