Numerical Simulation and Test Research of Pneumatic Drying on Biomass Fuel

Abstract:

Based on the mechanism of mass and heat transfer of the particles and air in drying tube，the mathematics model of pneumatic drying process was established which referred to straw fuel in straight horizontal tube. The simulating results were summed up. Test bed of pneumatic drying was established，the test results were summed up by making single-factor test on the test bed. The results of simulating and single-factor test were coincided, and the pneumatic drying process was divided into two parts which were high-speed drying area and slow drying area. The effect factors were analyzed which were initial water content, hot air temperature, mass of hot air and materiel. The most important factor in gas flow drying on straw fuel was summed up which was the mass of hot air.
