A solid fuel gasification system of the present invention enables omission of the char recycling means and enables production of syngas having a high calorific value and containing hydrogen and carbon monoxide as its main components. The gasification system has a pyrolysis area isolated from supply of air; a char combustion area producing a high temperature combustion gas by combustion of char of the pyrolysis area; a dust remover cleaning the combustion gas; combustion means for reheating the cleaned combustion gas to raise its temperature; and a steam heater for heating steam up to a high temperature by heat exchange between the combustion gas and the steam. The gasification system pyrolyzes the solid fuel with use of the high temperature steam so that syngas is produced, which contains hydrogen and carbon monoxide as its main components.
