    • The present invention relates to an externally heated microwave plasma gasifier and a synthesis gas production method, comprising mainly a vertically arranged cylindrical gasifier main body, a feeder apparatus in communication with the main body and arranged at the middle-section of the gasifier main body, an upper-layer steam nozzle arranged at a clearance area, a lower-level carbon dioxide/steam nozzle arranged at a bed-layer area, a synthesis gas outlet at the top part of the gasifier main body, a monitoring unit arranged on the outlet, and a microwave plasma generator arranged in the clearance area and on the upper end of the upper-layer steam nozzle; also provided is an external heating apparatus utilizing an external heat source for heating the gasifier main body, where the external heating apparatus is arranged integrally with the gasifier main body or arranged separately from the gasifier main body. Because the external heat source is used to supply heat, the amount of biomass chemical energy converted into thermal energy is reduced, so much so that no additional oxidizer is added for oxidation reaction, this allows for high effective ingredient content in the synthesis gas, for highly efficient and economic subsequent utilization process, and for comprehensive utilization in combination with various forms of energy.
    • 本发明涉及一种外加热的微波等离子体气化炉和一种合成气生产方法,主要包括垂直排列的圆柱形气化器主体,与主体连通并配置在气化器主体中部的进料装置, 布置在间隙区域的上层蒸汽喷嘴,布置在床层区域的下层二氧化碳/蒸汽喷嘴,在气化器主体的顶部的合成气出口,布置在出口处的监测单元 以及布置在上层蒸汽喷嘴的间隙区域和上端的微波等离子体发生器; 还提供了利用外部热源来加热气化器主体的外部加热装置,其中外部加热装置与气化器主体一体地设置或者与气化器主体分开设置。 由于使用外部热源来供热,所以转化成热能的生物质化学能的量减少了很多,因此不需要额外的氧化剂用于氧化反应,这允许合成气中高有效成分含量, 高效经济的后续利用过程,综合利用与各种形式的能源结合。
