Abstract

PURPOSE: To efficiently gasify a mixed slurry of carbonaceous solid particles of coal or the like and heavy oil at a high reaction rate by thermally decomposing the slurry; partially burning the surfaces of the resulting carbonaceous particles (char) with O2-contg. gas to gasify them; and treating the partially burned char with O2-contg. gas and steam or the like.
CONSTITUTION: Fluidized bed 3 of char particles fluidized with feed gases from O2- contg. gas introduction hole 8 and duct 10 and maintained at 700W900°C is formed in starting material thermal decomposition furnace 4. Coal-heavy oil slurry 2 hits against the particles of bed 3 and is thermally decomposed into char, tar and gas. The tar and the gas are taken out of outlet 6 and fed to a treating process, and the char is introduced into partial combustion chamber 18 through pipes 14, 16. In chamber 18 it is partially burned with gas from pipe 24 and O2-contg. gas from pipe 22. This char in furnace 18 then enters gasification furnace 30 through pipes 20, 28 and is oxidized with O2-contg. gas and steam or CO2-contg. gas from pipe 34. The resulting gas is fed to furnace 18 through pipe 24, and the residual ashes are discharged from outlet 6.
