How to recover and reuse heat from boiler blowdown water

Condensate Recovery and Return Condensate is a potentially valuable resource as it is high-purity, contains virtually no total dissolved solids and has high heat content. The purity and absence of dissolved solids makes condensate ideal for use as boiler feedwater.

Waste Heat Recovery | TLV - A Steam Specialist Company

Stack economizers, commonly used to heat water, are among the simplest type of waste heat recovery. Plant workers may be familiar with these common devices that recover waste heat. Boiler stack economizers use heat energy from the gas expelled in the heating process into the stack to heat boiler feed water and reduce the amount of energy
