Heat Recovery and Energy Efficiency Systems
topic
Textile drying heat recovery systems capture exhaust air thermal energy through plate heat exchangers or heat pumps that pre-heat incoming fresh air or process water using exhaust air energy, with stenter exhaust air typically at 80 to 120 degrees Celsius containing 40 to 60 percent of the total input energy recoverable through heat exchangers that reduce fresh air heating energy by 30 to 50 percent and reduce total stenter energy consumption per kilogram of fabric dried.
Role
Reduces the dominant energy cost of textile wet processing represented by stenter drying through systematic heat recovery from exhaust air streams that would otherwise waste 40 to 60 percent of input thermal energy, with heat recovery system installation providing the highest return on investment energy efficiency improvement available in textile finishing through reducing natural gas or steam consumption without compromising drying performance.
