目前苏联在頁岩油工业中所用干餾炉的处理量有90—100吨/日及35—40吨/日两种。1957年本文作者制订了在坚井式干餾爐内进行页岩合理加工的基本方法,並在工业化条件下对中部通入热载体和带有降低燃料层流体阻力装置的干餾新炉型进行了研究和試驗。在1958—1959年间,对大部分正在生产的处理量为90—100吨/日的頁岩干餾炉进行了改裝,結果大大改善了技术经济指标,使其处理量提高到130—150吨頁岩/日。处理量力35—40吨/日的頁岩干餾炉的改装与已改装的强制通风的干餾炉不同,它是利用排送机所造成的負压将空气自动吸入。对于这种干餾炉,虽然进行了长期試驗,但在提高处理量方面并未得到良好的结果。1959年,我們对在負压下操作的干餾炉,采用了将空气分别通入气化段及制备热載体的中間段的方法。
At present, the Soviet Union in the shale oil industry, the use of retort processing capacity of 90-100 tons / day and 35-40 tons / day two. In 1957, the author of this paper developed a basic method for shale rational machining in a well-type retort and carried out the industrialization of a new retort with a heat carrier in the middle and a fluid-drag reducing device with a reduced fuel bed Research and experiment. Between 1958 and 1959, the majority of the shale retortes in the pipeline that produced between 90 and 100 tons / day were being retrofitted. As a result, the technical and economic indicators were significantly improved to increase their throughput to 130-150 tons of shale / day. Processing capacity of 35-40 tons / day shale retort retrofit and retrofit forced-air retort, different from the negative pressure caused by the discharge machine will be automatically sucked into the air. Although such a retort furnace has been subjected to a long-term test, good results have not been obtained in terms of improving throughput. In 1959, we used a method of introducing air into the gasification section and the middle section of the heat carrier, respectively, for a retort operated under negative pressure.
