Gasification of coal or other carbonaceous material

Patent ·
OSTI ID:7101756
This patent describes a process of gasifying coal and the like by carbonizing as completely as practicable the material in an externally heated vessel. The process involves receiving the residue from said vessel directly into a generator, heating the residue in the generator to incandescence by a blast of air, and heating the said vessel externally by means of the sensible heat of the blow gases in addition by burning any producer gas formed. A steam blast is substituted for the air blast when the residue is incandescent. A portion of the produced water gas is passed through the material in the said vessel and is burned so as to heat the said vessel externally.
