基于Fluent的固定床生物质气化炉冷态压力场研究（Analysis of Fixed-bed Biomass Gasifier Cold Internal Pressure Field Based on Fluent）
生物质气化 下吸式气化炉 数值模拟
2010/12/29
以下吸式固定床生物质气化炉物理模型为研究对象，应用流体仿真软件Fluent，对冷态气化炉在单、双层气化剂配风工况下的床层压力场进行仿真研究。通过气化炉多点测压实验，对仿真结果进行验证。利用欧拉-拉格朗日方法分析气化炉冷态流场分布特性，根据伯努利方程说明气化炉床层压力场的变化原因。结果表明，仿真与实验结果的误差值在2.5%以内，气化剂配风工况的变化改变了炉内流场，双层气化剂配风使氧化层压力场平均值...

在分析焦油形成机理和裂解条件的基础上提出了一种高效的低焦油生物质气化技术。该技术将生物质低温热解和高温气化两个过程分开进行，且要求热解发生于350～500℃之间，气化温度控制在1000℃左右，气化剂当量比大约为0.3。分步气化保证了焦油强化裂解的高温条件，使其充分裂解为小分子不凝性可燃气体，从而降低了可燃气体中基础焦油质量浓度，提高了燃气品质。该工艺可使燃气中基础焦油质量浓度降低到20mg/m3以...
