The installation of a boiler economizer helps to solve this problem. An economizer is a unit that captures heat from the stack, and then returns it to a water system. To determine if a boiler economizer is right for your facility, look at your annual boiler fuel bill and subtract 5 to 10% of the cost.

boiler economizers and waste heat recovery

Boiler Economizers and Waste Heat Recovery

Two solutions exist for recovering the waste heat from boiler flue gases. Conventional economizers preheat boiler make-up or feed water. Condensing economizers recover both latent and sensible heat from the flue gas, and are able to raise boiler efficiencies to over 90%. II Applications

3 Use of Economizer with Waste-heat Boiler. Where the exit gas temperature is above ca.225°C and the ratio of flue gases to weight of water evaporated is low (e.g. < 3:1), the use of an economizer may be justified economically. Under these circumstances the exit gas temperature may fall to < 140°C.

The economizer also prevents flooding of the boiler with liquid water that is too cold to be boiled given the flow rates and design of the boiler. A common application of economizers in steam power plants is to capture the waste heat from boiler stack gases (flue gas) and transfer it to the boiler feedwater.
