Solid-fuel gasification system
A solid-fuel gasification system which not only enables the omission of a char recycle means but can produce a synthesis gas comprising hydrogen and carbon monoxide as main components and having a high calorific value. The solid-fuel gasification system comprises: a pyrolysis region to which no air is supplied
a char combustion region in which the char from the pyrolysis region is burnt to yield a high-temperature combustion gas
a dust remover which purifies the combustion gas
a combustion means for combustion gas reheating which elevates the temperature of the combustion gas from which dust has been removed
and a steam heater in which steam is heated to a high temperature by heat exchange between the combustion gas and the steam. The gasification system pyrolyzes a solid fuel with high-temperature steam to produce a synthesis gas comprising hydrogen and carbon monoxide as main components.
