CFD Simulation and Experimental Study on a Thermal Energy Storage–Updraft Solid Waste Gasification Device

A thermal energy storage–updraft gasification device is a type of reactor that should be considered for use in solid waste research can save energy. However, the operating parameters and internal flow field during its operation remain unclear. In this study, numerical model storage–solid based on computational fluid dynamics dense discrete phase (CFD-DDPM) which had almost never been used before was established, an innovative method causes particles to piled simulate process proposed according updraft fixed bed characteristics; meanwhile, experiments were conducted device. This study focused influence moisture content excess air coefficient particles, velocity, pressure, temperature, species distribution analyzed. Simulation results showed higher greater amplitude changes physical The pressure drop around 25 Pa–75 Pa different working conditions. combustible gas moist raise slightly with increase coefficient, while dry have opposite effect. Compared other devices same type, hydrogen production about 2–3 times higher. Our findings could facilitate analysis, predict status, provide theoretical basis improvement
