热煤气净化（除尘、脱硫）是热煤气联合循环发电（ＩＧＣＣ）技术中的关键步骤，北京煤化学研究所建成的热煤气净化试验工艺系统包括粉煤气化、热煤气除尘、热煤气脱硫３个基本单元．过程描述为出流化床气化炉的真实高压空气煤气可直接在陶瓷管除尘单元实施热态精除尘，出除尘单元的煤气可进一步到达间歇式或连续式脱硫单元完成热态精脱硫． Hot gas purification (dust removal, desulfurization) is a key step in hot gas combined cycle power generation (IGCC) technology. The hot gas purification test system built by Beijing Institute of Coal Chemistry includes three technologies, namely pulverized coal gasification, hot gas dust removal and hot gas desulfurization Basic unit The process described as outflow fluidized bed gasifier real high-pressure air gas can be directly in the ceramic tube dedusting unit to implement the hot fine dust, the dust removal unit of the gas can be further reached intermittent or continuous desulfurization unit to complete the hot fine desulfurization.
