Abstract:
1. A gasifier for a gas hydrate pellet characterized by comprising: a container main body which is insulated and hermetically sealed; a pellet-filling cylindrical body provided inside the container main body; a nozzle through which a heat medium for decomposing a gas hydrate pellet held in the cylindrical body is supplied; a gas-supply pipe through which a gas generated by decomposition of the gas hydrate is supplied to an outside; and a discharge pipe through which the heat medium is discharged, the gasifier characterized in that the pellet-filling cylindrical body has a side wall formed with such a slippage angle to reduce its contact resistance with the gas hydrate pellet held therein, a disposition space for the nozzle through which the heat medium is jetted is formed between an outer wall surface of the cylindrical body and an inner wall surface of the container main body, a flow space for the heat medium is formed between a lower edge of the cylindrical body and a bottom surface of the container main body, and the heat medium is jetted in a circumferential direction of the disposition space for the nozzle.
