1. Through air drying : Thermographic studies of drying rates, drying non-uniformity and infrared assisted drying
Sammanfattning : The removal of water is an integral part of papermaking. The drying process is responsible for a great share of the energy used in the paper machine. Premium grade tissue products are dried by through air drying. Large volumes of natural gas are burned to heat the air drawn through the paper web to achieve the drying. LÄS MER
2. Through air drying : The influence of formation and pulp type on non-uniform drying and air flow
Sammanfattning : The removal of water is an integral part of tissue paper production. Through air drying (TAD) is used for water removal when producing premium tissue grade products, however, at the price of higher energy demand. A better understanding of TAD may therefore lower the energy demand. LÄS MER
3. Through-Drying of Tissue Paper - Experiments and Modelling
Sammanfattning : In through-drying of paper, the energy required for drying is supplied by hot air, which is forced through the paper structure. The area for heat and mass transfer is the internal surface area of the paper, which is often many times larger than the external web surface area (xy-plane). LÄS MER
4. Development towards an efficient and sustainable biofuel drying
Sammanfattning : The usage of biofuel as well as wood fuel has increased in Sweden and all of Europe during recent decades, and there are several reasons to believe that this increase will continue. An important reason for this increase is that the environmental and climate problems caused by fossil fuels are becoming even more evident. LÄS MER
5. Energy Efficient Textile Drying
Sammanfattning : Traditionally, textiles were dried outdoors with the wind and the sun enhancing the drying process. Tumble dryers offer a fast and convenient way of drying textiles independent of weather conditions. Tumble dryers, however, consume large amounts of electrical energy. LÄS MER
