Production of hydrogen and removal and sequestration of

The balance of the coal, namely the char, is preferably burned in an air-cooled, slagging combustor that is attached to the existing or new coal fired steam boiler. Due to the removal of the volatile matter from the coal, the total coal flow to the plant is increased to the point where the heat input from the char equals that of the original
