摘要：
For the problem of drying biomass particles, based on gas-solid two phase flow theory, this paper establishes a mathematical model of straight tube flue gas flow drying, and compiles MATLAB language program to sovle the model. By changing the particle flow, flue gas flow, flue gas temperature and other single factor, it analyzes the impact of gas-solid relative velocity and heat transfer temperature difference in the drying process. Last it obtains the degree of influence on the drying efficiency: particle Flow> flue gas flow> flue gas temperature. (C) 2017 The Authors. Published by Elsevier Ltd.
