Abstract
A biomass gasification system and operating method thereof are able to prevent hindrances caused by the tar component in a fuel gas and to thermally utilize a fuel gas containing a tar component. A gas reforming tower, able to thermally crack the tar component in a fuel gas by increasing the temperature thereof to a process temperature, is connected to a gas supply system, which routes a biomass-source fuel gas generated by a gasification furnace, to a utilization system. Fuel gas from the gas reforming tower is routed through a fuel gas induction system to the gasification furnace for use as fuel therein during the time required for the gas reforming tower to attain the process temperature.
Claims4
A biomass gasification system comprising:
- a gasification furnace which generates a fuel gas from biomass;
- a reforming device which attains a process temperature at which a tar component within the fuel gas is thermally cracked, connected to a supply system which feeds fuel gas from said gasification furnace to a utilization system;
- and
- a fuel gas induction system that feeds the fuel gas from said reforming device to said gasification furnace as fuel to power operation of said gasification furnace during a time when said reforming device has not yet attained a process temperature.
A biomass gasification system operating method comprising:
- directing fuel gas from a reforming device, within which temperature of the fuel gas is increased to a point at which a tar component within the fuel gas generated from biomass in a gasification furnace is thermally cracked, to said gasification furnace as fuel to be combusted by said gasification furnace during a time when the temperature of said reforming device is below a process temperature.
