Calculated Design Of An Economizer In Fire Tube Boiler

The Economizer: What, Why, and How? - Boiler Blog | …

14/4/2017 · 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--ZBG

Boiler economizer calculation 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.
