Waste Heat and Energy Recovery System from Smelter Off

Heat pumps consist of cycles which include the Steam and Organic Rankine cycles, both of which can be used to recover heat from exhaust gases (Hall et al, 2011). The systems use waste heat boilers to recover heat and then heat steam for the Rankine Cycle. Waste heat boilers for these applications recover the heat contained in flue gas (under
