| 摘 要： | 针对循环流化床气化炉普遍存在的飞灰及底渣含碳量高、煤炭利用率低、气化效率不高等问题，研制了外部流化床燃烧气化反应器。通过冷态试验，研究了外部流化床燃烧气化反应器的布风板空板阻力和料层阻力与流化风量的关系，测定了飞灰在反应器内的停留时间，研究了外部流化床燃料气化反应器的输送特性。试验证明外部流化床燃烧气化反应器对于降低循环流化床气化炉飞灰和底含碳量是完全可行的。

| Abstract: | In line with the problems of high carbon content in fly ash and slag, low utilization ratio of coal, and inefficiency of gasification commonly existent in the circulation fluid bed gasifier, a gasifier with external fluid bed combustion has been developed. Through the cold test, the relationship of the resistance of empty blast distributors and material layer in the gasifier with the fluidized blast volume is studied, the residence time of fly ash in the gasifier is determined, and the transport characteristics of the gasifier is studied. The experiment proves that this gasifier is completely feasible for reducing the carbon content in fly ash and slag from the circulation fluid bed gasifier. |
