Boiler Economizer Exhaust Heat Recovery Systems-Thermal

DCE recovery furnace means a kraft or soda recovery furnace equipped with a DCE that concentrates strong black liquor by direct contact between the hot recovery furnace exhaust gases and the strong black liquor (Bajpai, 2008). In DCEs, liquor is concentrated by bringing it into direct contact with hot flue gases from the recovery boiler.

HEAT RECOVERY BOILERS. Boilers of this type generate steam by extracting heat from hot fluid, generally a gas, which is produced as a by-product of a chemical reaction and has no intrinsic value as a chemical, or which is in the form of exhaust from a gas-turbine or internal combustion engine. Heat recovery boilers are also often found in
