中华人民共和国的油母页岩加工工业中,抚顺式页岩干馏炉最为普遍。这种炉型的一个基本原则是将页岩半焦进行气化,因此往于馏炉的底部送入主风。对加工贫矿页岩来说,其半焦中的含碳量仅在5%左右,抚顺式干馏炉就显示出了严重的缺点。原则上讲,含碳量不超过5%的燃料在固定层内未必能进行正常的气化,这不必多谈,在实际上,连为正常的气 In the oil shale processing industry of the People’s Republic of China, the Fushun shale retorting furnace is the most common. One of the basic principles of this type of furnace is to gasify the shale semi-coke so that the main air is fed to the bottom of the distillation furnace. For the processing of poor shale, its carbon content in the semi-coke is only about 5%, Fushun type retort showed a serious shortcomings. In principle, a fuel containing up to 5% carbon may not be able to be normally gasified in the fixed bed, which need not be talked about. In fact, even the normal gas
