根据魯奇式煤低溫干餾爐的經驗,先将煤預热,可以提高干餾爐处理能力,減少干餾瓦斯量,以节省回收设备。撫顺油母頁岩一般含有5％左右表面水,而焦油放出溫度在300℃以上,因此也可采用預热措施,将頁岩加热脫水后再进行干餾,使頁岩在干餾段的停留时間縮短。这样干餾炉的处理能力就可以提高,同时由于进入干餾段的頁岩溫度均匀,使干餾爐內火层平稳,对提高采油率大为有利。在苏联专家札布罗金同志与吉雅契柯夫同志的建议与指导下,首先在石油一厂100吨試驗爐上試驗成功。其后在石油二厂修建了三段爐爐群,已于1959年12月投入生产,几个多月来的运轉情况非常良好。三段炉的投入生产标誌着我国人造石油工业又向前跨进了一步,給今后抚順炉提高处理能力开辟了新的途径。这是在党的正确领导下,同志們发挥了冲天干劲的结果。
According to Lurgi coal low temperature carbonization furnace experience, the first coal preheating, can improve the processing capacity of retort, reduce the amount of dry gas, in order to save recycling equipment. Fushun oil shale generally contains about 5% surface water, while the tar release temperature above 300 ℃, so you can also use preheating measures, the shale heat dehydration and then dry distillation, so stay in the dry distillation section shale reduction time. In this way, the processing ability of the retort can be improved, and at the same time, the temperature of the shale entering the retort is even, and the fire layer in the retort is stable, which is greatly beneficial to improving the oil recovery rate. Under the suggestion and guidance of Comrades Zabroldin and Jiyachev in the Soviet Union, the experiment was first successfully carried out in a 100-ton pilot furnace of the first oil plant. Afterwards, a three-stage furnace group was built in No.2 Oil Factory and was put into production in December 1959. The operation in a few months has been very good. The commissioning of the three-stage furnace marks a further step forward for China’s man-made petroleum industry and opens up new avenues for improving the handling capacity of Fushun furnace in the future. This is the result of the energetic drive exerted by our comrades under the correct leadership of the party.
