Optimal Dew Point in Paper Drying Process

摘要

To produce a good quality material with minim power specific consumption, it has to know the material isotherm of sorbtion. For an analytical determination of material isotherm of sorbtion it has to make a drying mathematical model. This allowed us to know in every moment the local temperature and the moisture content of the material. In the other hand, using above information, the present paper presents a diagram of the wet air (Moliere) which is done for a certain working sketch and various working conditions. Thus, the wet air condition (dew point) is determined at the paper machine outlet. Conclusions are drawn concerning the value of the specific thermal energy consumption.
