10/1/2020 · As combustion exhausts pass through one chamber, the bricks absorb heat from the combustion gas and there is increase in the temperature. The flow of air is then adjusted so that the incoming combustion air passes through the hot checker work, which transfers heat to the combustion air entering the furnace.

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 ).

27/11/2017 · Secondary heat recovery systems capture excess energy in the exhaust stream of processes or oxidizers. On the surface, heat recovery makes good sense: Capture the waste energy and repurpose it rather than throwing it out an exhaust stack. The concept sounds relatively straightforward. As with most things, however, the proof lies in the details.
