Sažetak
Drying is one of the most energy-consuming process in textile processing. with energy expenditures up to 25% of the total production energy requirements. It serves to reduce the moisture content in textile products after wet processing. Energy savings in drying process using fabric stenters with indirect heating system using hot oil boiler and thermal fluid distribution system have been calculated. The heat and mass transfer by blowing heated air through the humid textile material leads to the moisture of the material being transferred to the air. The system was calculated using various system combinations to increase system efficiency and reduce fuel consumption. Applying processes using recuperation, recirculation and combination of both to increase drying efficiency could optimize drying techniques based on thermal energy. Those energy-savings also result in improvements of the production process with respect to environment. Fuel savings with indirect heating system show fuel savings over the real process of 26.06% with recirculative, 30.86% with recuperative and 41.34% with combined process.
