CHAR COLLECTION SYSTEM AND CHAR CONVEYANCE METHOD

WIPO Patent Application WO/2015/093119

A1

A char collection system capable of easily determining whether or not a char removal pipe is blocked by char. The char collection system comprises: a stand pipe (31) forming a vertically-downwards facing flowpath (33) through which char is conveyed; and a differential pressure gauge (41) that measures the pressure difference between the pressure in a downstream area (45) in the vertically-downwards facing flowpath (33) and the pressure in an upstream area (46) in the vertically-downwards facing flowpath (33). The pressure difference fluctuates when char accumulates between the downstream area (45) and the upstream area (46) in the vertically-downwards facing flowpath (33). As a result, this kind of char recovery system is capable of easily determining whether or not the vertically-downwards facing flowpath (33) is blocked by char, on the basis of the measured pressure difference.
