How to Match Proper Thermal Oil Boiler Capacity for Coating Flocking Machines
Proper thermal oil boiler sizing directly decides flocking coating quality and energy efficiency, a core topic in textile finishing equipment industry this year.
Boiler capacity relies on total heat load of drying ovens, coating rollers and pipeline heat loss. Engineers calculate power via material throughput, target curing temperature (160–220℃) and temperature rise, plus 15–20% safety margin for unstable running conditions.
A single standard flocking line usually fits 120–240kW heaters; dual-line production requires 300–500kW models. Undersized boilers cause temperature fluctuation, fuzzy flocking and low output; oversized ones trigger extra fuel waste.
Manufacturers suggest gas-fired thermal oil furnaces with PID constant-temperature control for stable coating curing, cutting production defect rates by over 12% with matched heating capacity.
