In order to reduce heat consumption and improve the efficiency of water evaporation in paper machine dryer section, advanced measuring techniques were used to obtain temperature and humidity parameters. Further, based on the principle of air pressure distribution and through the intrinsic relation of temperature and humidity parameters and Matlab programming analysis, dynamic characteristics of these parameters and heat energy saving principle were systematically analyzed. The study indicated that paper drying curve is affected by the condition of dryer steam together with air supply, and the dryer steam consumption varies with the change of air supply; lots of paper machine dryer sections are in normal state, but the steam consumption is not the lowest. By optimizing the parameters, steam consumption can drop significantly, and under the premise of ensuring paper quality the best energy-saving effect can be achieved by optimizing and controlling the zero-point of the heat-air exchange system.
