这是大平原煤制气经验启示中的一段话，高手指导下！？ 5.5.c implications for future projects 对未来项目的启示 assumption: the items identified below are focused on issues relating to ash handling for a drybottom gasifier. in addition, some of the ash-handling issues faced at the gpsp may be feedstock-specific and relevant only to gasification of north dakota lignite. 假定：以下项主要集中在干法排灰气化炉排灰问题。此外，一些gpsp（great plain synfuels plant）所面临的一此排灰问题可能只针对具体原料，这仅关北达科特褐煤气化。 1.if the ash discharge from the gasifiers is at an elevated height compared to the disposal site/departure point, sluiceways for ash handling can rely on gravity flow rather than mechanical pumping, and will be less susceptible to changes in ash properties. 如果气化炉的排灰与处置场/排灰点高一定高度，可不用机泵，而利用重力流溜槽排灰，这对灰份性质变化敏感性影响较小。 2.ash handling designs, which plan for variations in ash particle sizes related to variations in gasifier/feedstock performance, will be more robust. . 灰处理设计，要考虑到气化炉/进料性能波动造成的灰粒径变化，要更有鲁棒性。 3.maintaining a minimum velocity of slurried ash will prevent the settling of ash particles. dumping ash from the ash locks in a consistent, uniform pattern enables an even and constant flow in the sluiceways 维持灰浆的最小流速以预防灰颗粒的沉积，连续稳定灰锁卸灰可使溜槽达到均匀稳定的流速。查看更多
