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.
