Use Feedwater Economizers for Waste Heat Recovery

Waste Heat Recovery A feedwater economizer reduces steam boiler fuel requirements by transferring heat from the flue gas to incoming feedwater. Boiler flue gases are often rejected to the stack at temperatures more than 100°F to 150°F higher than the temperature of the generated steam. Generally, boiler efficiency can

Waste heat and water recovery from natural gas boilers

Dec 15, 2017 · For natural gas boilers, the hydrogen content of the raw fuel is high, and the latent heat usually occupies a large proportion of the total waste heat, . The technologies based on condensing heat exchangers recover heat by cooling the flue gas under its dew point with extra cooling medium, thus the final state of the flue gas is limited by the
