Process of making combustible gas
This patent describes a process of generating coal and water gas by admitting air for blasting at an intermediate level to a body of coal contained in each of two generators, and thereby heating the fuel to incandescence. The blast gases are passed downwardly and into corresponding regenerators, adding additional air for the combustion of the blast gases therein. The process continues by alternately admitting steam to one of the two generators at the same level at which air was previously admitted and passing the steam downwardly through the incandescent fuel to form water gas. The water gas passes into and up through the adjoining regenerator and down the second regenerator. This results in superheating the water gas, which is passed into the second regenerator and upwardly through a body of fuel having a layer of uncarbonized coal. This passes to a gas outlet above the coal, whereby mixed coal and water gas is produced.
