Heat can be recovered from Corrosive and Fouled flue gas. Download White paper. In the industry, significant amounts of energy are lost via the stack. Stack losses are concentrated and therefore a great place to recover heat. However, acid dew point corrosion has been stopping operators from recovering this heat. But not any longer!

WASTE HEAT RECOVERY TECHNOLOGIES FROM HEATING BOILER FLUE GAS

Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator. Quite often, the flue gas refers to the combustion exhaust gas produced at power plants. Its composition depends on what is being burned, but it will usually consist of
