Stable fuel flow can be controlled in a combustion apparatus by providing: a fuel tank (38) which stores LPG; a fuel line (39) which supplies the LPG in the fuel tank (38) to a coal gasifier (12); a pump (102) which is disposed on the fuel line (39) and which boosts the pressure of the LPG; an evaporator (103) which is disposed on the fuel line (39) and which heats the LPG after the pressure of the LPG has been boosted; a flow regulating valve (104) which is disposed on the fuel line (39) and which regulates the flow of the pressurized and heated fuel; and a control device (105) which boosts the pressure of the LPG beyond the critical pressure using the pump (102) in response to the operating demands of the coal gasifier (102), and which sets the flow of LPG to be supplied to the coal gasifier (102) using the flow regulating valve (104) after the LPG has been heated beyond the critical temperature by the evaporator (103).
