Boiler Economizer Types And Efficiency Calculation--ZBG

Boiler Economizers. Economizers are heat exchangers that transfer the heat in the flue gas to another medium‚ generally the boiler feed-water‚ although other streams are sometimes used such as make-up water. There are 2 types of economizers: non-condensing and condensing.

Why Economizer and Air Pre-Heaters are Provided in Boilers

Economizer and Air Pre-Heaters are Provided for Heat Recovery. In case the boiler designers do not want to go for a combination of tubular and regenerative air pre-heater, then they have a choice of tri-sector regenerative air heater. Normally the ambient air is heated to about 300 to 350 degree centigrade.

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

Apr 14, 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.
