In this paper, millions of tons of coal indirect liquefaction demonstration project as the background, in order to gasification technology than choosing to focus on, according to the project location matching mine raw coal the coal adaptability and target product needs, determine the selection of gasification technology principles, namely the industrial application of the technology performance, investment, cost, efficiency, environmental impact, long period operation experience. On this basis, to the domestic and foreign coal gasification technologies for a more detailed analysis and comparison, and ultimately determine the oil produced by coal gasification technology selection device for multi opposed multi-burners coal-water slurry gasification technology.Introduced the multi opposed multi-burners coal-water slurry gasification technology application situation, including the development of history, technical features, as well as in the commercial operation of the optimization, summarizes the large-scale device performance characteristics and advantages. Discusses the effect of process conditions on gasification device, discusses the device in instrument control system, key equipment selection and layout of pipeline, supporting engineering design and other aspects. Through optimizing the engineering design, the gasification device operation to achieve high efficiency, security and stability, long cycle of higher level, the overall level of demonstration device to achieve the leading domestic, international advanced.
