Energy Recovery in Yarn Heat Setting Operations
topic
Yarn heat setting energy recovery systems capture condensate from autoclave steam setting and return it to the boiler feed water system, recover exhaust steam from chamber purging through heat exchangers preheating incoming steam condensate, and apply waste heat from hot yarn cooling air to building space heating, with total energy recovery potential of 20 to 35 percent of gross heat setting energy consumption from these combined recovery measures.
Role
Reduces the steam energy cost of yarn heat setting operations through systematic recovery of thermal energy from steam condensate, exhaust steam, and yarn cooling heat that would otherwise be wasted, with energy recovery implementation being both an economic return investment and a contribution to the sustainability performance reporting that yarn manufacturers increasingly require to satisfy brand customer sustainability audit requirements.
