Method of gasification of bituminous coal
This patent describes a method for the complete gasification of bituminous coal in a single vessel. It involves an improvement consisting in maintaining a descending fuel bed at the top of which is uncarbonized coal and at the bottom of which is coke immediately supporting the coal; establishing a bottom hot zone across the entire horizontal area of the coke by airblasting the coke from the bottom of the coke upward; establishing a second and upper hot zone in the coke immediately supporting the uncarbonized coal by applying to the coke a second independent airblast at that point; excluding the blast gas from the uncarbonized coal; and then generating blue water gas by upwardly steam blasting the coke at the lower hot zone. The process then involves passing the blue water gas thus formed upward through the upper hot zone whereby the blue water gas is highly heated. The highly heated blue water gas is then passed upward through the superimposed coal to effect its carbonization to coke.
