  • boiler economiser - thermal power tech

    BOILER ECONOMISER - Thermal Power Tech

    In a boiler system, an economizer captures the heat of the flue gas and transfers it to the feed water. The process is simple. As the flue gas exits the boiler, it enters an economizer with finned tubes. The finned tubes absorb the heat and raises the temperature of the boiler feed water, lowering the needed energy input.

    Boiler Economizer Types And Efficiency Calculation--Zozen

    There are 2 types of condensing economizers: heat exchanger and direct contact (spray). They capture much more heat and therefore can raise the overall boiler efficiency by 10% to 15%. For condensing economizers to be the most effective‚ low temperature heat sinks are required to bring the flue gas temperature well below the flue gas condensing temperature. Boiler economizer …
