  • Patent number: 10465134
    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 (31) forming a vertically-downwards 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 flowpath (33) and the pressure in an upstream area (46) in the vertically-downwards flowpath (33). The pressure difference fluctuates when char accumulates between the downstream area (45) and the upstream area (46) in the vertically-downwards flowpath (33). As a result, this kind of char recovery system is capable of easily determining whether or not the vertically-downwards flowpath (33) is blocked by char, on the basis of the measured pressure difference.

  • Patent number: 9890331
    Abstract: A gasification facility which uses flammable gas as a carrier medium for air-transporting powder fuel, used as a gasification raw material, to a gasification furnace and which can safely release the flammable gas, exhausted from a fuel feed hopper, to the atmosphere. In the gasification facility using flammable gas as a carrier medium for transporting pulverized coal as powder fuel from a pulverized coal feed hopper (7) to a gasification furnace (11), the flammable gas discharged from the pulverized coal feed hopper (7) is subjected to incineration treatment and then released to the atmosphere, so that safe release to the atmosphere can be implemented.
