The experiment indicated that temperature field of gasification furnace had been great affected by gasification power, types of coal, material of collecting gas mantle, air exhaust velocity, etc.
实验结果表明,气化功率、煤的种类、集气罩材料和排气速率等对气化炉内温度场均有较大影响;
With the augment of the distance to furnace surface, the temperature grads of the furnace minish, anear collecting gas mantle area, the temperature grads increase with the height.
炉内温度梯度随距炉表距离的增大而减小,靠近集气罩区域,温度梯度随高度增加而增加;
Temperature field near the gasification furnace surface was controlled by radiation field, and temperature field near collecting gas mantle area was controlled by convection field.
气化炉内的炉表近区域温度场主要由辐射场控制,集气罩近区域温度场受对流场控制。
