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