  • What is the function of the economizer? - Boiler basics

    An economizer is similar to the convection section in a direct-fired heater. Both oper-ate under the energy-saving concept of recovering some of the heat from the hot flue gases before they are lost out of the stack. The typical improvement in efficiency of a boiler with an economizer is 2 to 4 percent. Steam Distribution SystemLearn More

  • Boiler - an overview | ScienceDirect Topics

    James G. Speight, in Reaction Mechanisms in Environmental Engineering, 2018 5.2.3 Boiler Slag. Boiler slag is a byproduct produced from a wet-bottom boiler, which is a special type of boiler designed to keep bottom ash in a molten state before it is removed. These types of boilers (slag-tap and cyclone boilers) are much more compact than pulverized coal boilers used by most large utility Learn 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

  • Fossil Fuel Power Station| Coal fired steam boiler
