摘要:
A coal separation unit for a gasification system includes a vessel having a top portion and a bottom portion, a first inlet configured to receive a feed stream including at least coal and ash from a grinding unit, a second inlet configured to receive a wash fluid stream, a first outlet configured to convey a low-ash feed stream, and a second outlet configured to convey an ash-rich stream. In operation, the feed stream is washed with the wash fluid stream in the separation unit to separate at least a portion of the ash from the coal. The separated ash settles to the bottom portion of the vessel and is conveyed via the second outlet as the ash-rich stream. The separated coal floats to the top portion of the vessel and is conveyed via the first outlet to a gasification unit as the low-ash feed stream.
摘要(中):
用于气化系统的煤分离单元包括具有顶部和底部的容器,第一入口构造成从研磨单元接收至少包括煤和灰分的进料流,第二入口构造成接收洗涤流体流 ,第一出口,构造成输送低灰分进料流,以及第二出口,其构造成输送富灰流。 在操作中,进料流用分离单元中的洗涤流体流洗涤以将至少一部分灰分与煤分离。 分离的灰分沉降到容器的底部,并经由第二出口作为富灰流输送。 分离的煤漂浮到容器的顶部,并且经由第一出口被输送到作为低灰分进料流的气化单元。
