Exhaust heat from combustion typically leaving the stack and into the atmosphere is instead transferred from the exhaust stream by means of a Cain economizer. This lost BTU is now captured and saved to various heat sinks such as boiler feedwater, cold makeup water, process water, swimming pool water, glycol, and thermal fluids.

Older recovery boilers often use DCEs for final concentration of black liquor before combustion in the recovery boiler. 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 ).

The efficiency of the own plant increases noticeably by this technology, whereby expensive primary energy can be saved, and the CO²-emission can be reduced. It is therefore not only cost-effective, but also environmentally friendly. Often a exhaust gas heat exchanger can achieve a similar result for a fraction of the cost as a complete replacement of the heating system.

Any exhaust gas stream with temperatures above 250 F has the potential for significant waste heat recovery. Consumers of waste heat energy can be found in almost any facility and are easy to locate. Typical examples include plant process heating, combustion air pre-heating, boiler feedwater pre-heating, and building heat.
