SJ型气燃方炉是神木三江煤化工公司开发的新一代干馏炉,起初应用烟煤干馏,2006年三江煤化工建立了一套中试装置,处理量为25dT,对窑街油页岩进行干馏试验,达到可运行状态,并在2010年在窑街投产8台SJ-IV型方炉,同年试车,并正式投入生产,用于处理粒径在8~65 mm富油页岩干馏。本文通过对SJ-IV型气燃方炉在窑街油页岩干馏过程中原料、工艺及产品做以分析,确保在油页岩干馏行业能起到良好的示范。
SJ-type gas-fired square furnace is a new generation of retort furnace developed by Shenmu Sanjiang Coal Chemical Company. At first, it was applied to dry distillation of bituminous coal. In 2006, Sanjiang Coal Chemical established a pilot plant with a capacity of 25 dT for retorting oil shale from Kao Street Test to reach the operational status. In 2010, 8 SJ-IV type square furnaces were put into operation in Yajie. The same trial was put into operation in the same year and the project was officially put into production for the treatment of oil-rich shale with a diameter of 8 to 65 mm. This paper analyzes the raw materials, technology and products of SJ-IV gas-fired square furnace in the kiln street oil shale retorting process to ensure good demonstration in the oil shale retorting industry.
