Heat Recovery from Dyeing Machine Effluents
topic
Dyeing machine heat recovery systems capture thermal energy from hot effluent discharged at 60 to 90 degrees Celsius from dyeing machine cooling steps using heat exchangers that transfer heat to incoming cold fresh water for dyeing machine fill or process water preheating, achieving 40 to 70 percent recovery of the cooling cycle heat that represents a significant fraction of total dyeing machine steam consumption per batch.
Role
Reduces dyeing machine steam consumption through systematic recovery of the significant thermal energy content of hot cooling effluent that is normally discharged to drain, with heat recovery from dyeing machine effluent being one of the highest-impact and lowest-capital energy efficiency investments available in textile dyehouse operations due to the high temperature and volume of hot effluent discharged during routine cooling cycles.
