Abstract:
The purpose of this research is to investigate the specific energy consumption in S-PVC pneumatic drying. In thepresent work, computational fluid dynamics is utilized to predict the hydrodynamics and drying mechanisms of a threedimensional,dilute-phase, gas-solid turbulent flow in a laboratorial-scale and the experimental study is carried out in two pilotscalespiral pneumatic conveying. The influence of diameter and length of the dryer was investigated in two pilot-scale dryers.In addition, the effects of gas velocity and temperature, particle temperature, gas density and moisture content on the dryerperformance were examined. The results of energy analysis show that by increasing the gas temperature by 50 K, the specificenergy consumption will be decreased as much as 37.7, 42.1, 45 percent at flow rate of 35476, 42570, 49665 3 m /h .
