Abstract

PURPOSE:To dispense with a char-burning burner and to remarkably simplify a raw material-feeding system of a gasification furnace, by supplying produced char to a pulverized coal distributor, mixing the pulverized coal with the produced char and supplying the mixture through a pulverized coal burner to a gasification furnace. CONSTITUTION:Pulverized coal in the lower-stage normal-pressure hopper 1 and the upper-stage normal-pressure hopper 1' are introduced into intermediate coal hoppers 2, 2', respectively. The intermediate hoppers are pressurized to a pressure higher than that of a gasification pressure and the amount of pulverized coal discharged from coal-feeding hoppers 3, 3' of the lower and the upper stages are separately controlled with coal feeders 4, 4'. The pulverized coal is mixed with carrier gases 5, 5' in a pulverized coal-carrier gas mixers 6, 6'. The mixture is distributed to each burner group by distributors 7, 7' and supplied to a gasification furnace 8. The produced gas containing char is treated with a solid-gas separator 9 and the separated char is introduced into a char hopper 10. The char is then supplied to a pulverized coal distributor 7, mixed with pulverized coal, passed through a burner and supplied to the gasification furnace.
