- Abstract:
- Numerical simulation study is conducted for a pressurized spouted-fluidized bed coal carbonizer, in which hydrodynamics of pressurized spouted-fluidized bed, chemical reactions and energy balance are taken into account. The effect of operating conditions such as bed pressure, air and steam mass flow ratio, temperature on product compositions in the bed is investigated. According to the calculated results, bed pressure and bed temperature have the key effects on coal semi-gasification.
- 本文对增压喷动流化床中煤半气化进行了模拟, 在模型中考虑了增压喷动流化床的物理特性、化学反应、能量平衡, 对床压、床温、空煤比, 汽煤比对生成煤气成分的影响进行了研究.计算结果表明增压喷动流化床中床压、床温对煤的半气化影响较强.
