摘　　要：根据无焰氧化技术的思想提出了一种新型干煤粉气流床气化炉,运用试验和数值计算方法对高灰熔点煤粉在炉内气化反应过程进行了研究。试验和模拟结果证实了该炉型结构能够使炉内温度场均匀,炉内温度梯度显著降低,实现了无焰氧化技术的基本反应特征,使煤粉气化反应空间化;同时炉内平均温度水平上升,气化强度增强,排渣口处温度水平上升,满足了高灰熔点煤种的气化要求。According to the idea of the flameless oxidation technology,proposed was a new type dry pulverized coal GFB(gas fluidized bed) gasifier.By using the experimental and numerical calculation method,studied was the in-furnace gasification reaction process of the pulverized coal with a high ash melting point.The test and simulation results have verified that the structure of the furnace can result in a uniform temperature field in the furnace,a remarkable drop of the in-furnace temperature gradient,realizing the...
