Patent ID: 8070484

Claim:
A combination burner for the gasification of pulverized fuels with an oxidation component containing free oxygen for pressures between ambient pressure and high pressures of 80 bar and temperatures between 800-1800Â° C., comprising: a centrally arranged tube that leads to a mouth portion of the burner; an annular combustion gas channel arranged concentrically around the central tube that leads to the mouth of the burner that provides a combustion gas to the burner; an annular oxidation component channel arranged concentrically around the annular combustion gas channel that leads to the mouth of the burner and provides an oxidation component to the burner; an annular cooling channel arranged concentrically around the annular oxidation component channel that provides a coolant to the burner; a pulverized fuel burner oxidation component annular channel arranged concentrically around the annular cooling channel that provides an oxidant to the burner; a further annular coolant channel arranged concentrically around the pulverized fuel burner annular channel that provides a further coolant to the burner; a pulverized fuel annular channel arranged concentrically around the further annular coolant channel that provides pulverized fuel to the burner; and a second further annular coolant channel arranged concentrically around the pulverized fuel annular channel that provides a second further coolant flow.
