A gasifying apparatus comprises a gasifier, a reformer and a heating device. The gasifier produces a thermal decomposed gas with use of a thermal decomposition reaction of a liquid or solid fuel such as waste or coal, and the heating device heats a low-temperature steam and air so as to be a high-temperature steam and air, which have a temperature equal to or higher than 700 deg. C. The gasifying apparatus has feeding means including fluid passages for feeding the high-temperature steam and air to the gasifier and the reformer. In a thermal decomposition area of the gasifier, the liquid or solid fuel is thermally decomposed to produce the thermal decomposed gas with sensible heat of the high-temperature steam and air and with the heat generated by an exothermic oxidation reaction between the high-temperature air and the liquid or solid fuel. In the reformer, the thermal decomposed gas is reformed in the existence of the high-temperature steam so as to be a high-temperature syngas. The steam reforming reaction of the liquid or solid fuel is carried out with an exothermic reaction between the high-temperature air and hydrocarbon contained in the thermal decomposed gas and with an endothermic reaction between the hydrocarbon and the high-temperature steam.

Apparatus and method for gasifying liquid or solid fuel

A heating apparatus for heating supply of gaseous fluid heats a relatively low temperature gaseous fluid and feeds a heated supply flow to a high temperature gaseous fluid introduction equipment. The heating apparatus has heat exchangers provided with fluid passages through which the low temperature fluid flow passes, a splitting area for dividing a heated supply flow H of gaseous fluid, which is heated by the heat exchanger, into first and second heated gaseous streams H , H , and combustion areas in which a combustion reaction of combustible matter takes place in the existence of the first heated gaseous stream. The heated supply flow or the first stream is introduced into the combustion area and the combustible matter is fed thereto, and the combustion area causes the combustion reaction of combustible matter in the existence of the heated supply flow or the first stream. Hot gas produced by the combustion reaction is exhausted through the heat exchanger. The heat exchanger has a regenerator which accumulates heat in its heat-transferable contact with the hot gas and emits the heat in its heat-transferable contact with the low temperature gaseous fluid. The heating apparatus heats or preheats the low temperature gaseous fluid to a high temperature and feeds the second heated gaseous stream to the equipment.
