    • Systems and methods for step-wise cooling high pressure and high temperature ash discharged from the gasifier used for gasification of carboneous materials, wherein a high pressure cooler cools the ash under the operating pressure of the gasifier, which may be followed by a depressurizer which brings the cooled ash to safe-handling temperature. A low temperature ash cooler may also be optionally used. Also provided is a system where a wet scrubber is used to clean the syngas from the gasifier, the waste water blow down from the scrubber is used to cool the hot ash either in the high temperature ash cooler, or the low temperature ash cooler. Steam generated in the ash coolers is supplied back to the gasifier to reduce steam consumption
    • 用于分阶段冷却从用于含碳材料气化的气化器排出的高压和高温灰的系统和方法,其中高压冷却器在气化器的操作压力下冷却灰,然后可以通过减压器 冷却后的灰分达到安全处理温度。 低温灰分冷却器也可以选择使用。 还提供了一种系统,其中使用湿式洗涤器从气化器清洁合成气,从洗涤器排出的废水用于冷却高温灰分冷却器或低温灰分冷却器中的热灰。 在灰渣冷却器中产生的蒸汽被返回到气化器以减少蒸汽消耗
