ABSTRACT:
A method for thermally decomposing and gasifying either liquid or solid combustible material in a single reactor filled with working medium in a high active fluidization, said reactor being provided with two partitions, one of which is extended downwards upto the lower portion of the reactor, while the other is vertically extended at the lower and middle portions thereof substantially at a right angle to the first partition, whereby the reactor is divided into two sections, that is, thermal decomposition and gasification section and combustion and heating section, so that thermal decomposing and gasifying are performed by way of supplying the combustible raw material into the downwardly travelling working medium and at the same time supplying steam thereinto for generating and maintaining the high active fluidization of the working medium in the thermal decomposition and gasification section, while burning and heating are performed by way of supplying air or steam mixture gas of oxygen and steam into the upwardly travelling working medium accompanied by carbonaceous material produced during the preceding process to burn said carbonaceous material in the combustion and heating section. The produced combustible gas as well as combustion gas are removed through gas outlet ports located at the upper end portion of the reactor. A part of thermal energy required for thermal decomposing and gasifying in the thermal decomposition and gasification section is provided by way of thermal conducting through the vertically extending partition from the combustion and heating section kept at a higher temperature.
