Claim 1

IN A PROCESS FOR THE PREPARATION OF CARBON MONOXIDE AND HYDROGEN BY THE PARTIAL COMBUSTION OF PULVERIZED COAL IN THE PRESENCE OF STREAM AND WITH OXYGEN OF AT LEAST 90% PURITY WHEREIN THE SLAG IS CONTINUOUSLY DISCHARGED FROM THE REACTION ZONE IN THE MOLTEN STATE, THE STEPS WHICH COMPRISE MIXING PULVERIZED COAL WITH STREAM AND OXYGEN OF AT LEAST 90% PURITY, INJECTING THE COAL-STREAM-OXYGEN MIXTURE INTO A COMBUSTION ZONE AND SUBJECTING IT THEREIN TO PARTIAL COMBUSTION, SEALING ALL OPENINGS OF THE COMBUSTION ZONE FROM THE ATMOSPHERE, THE INLET BY THE COALSTREAM-OXYGEN MIXTURE, THE PRODUCT GAS EXIT BY THE FLOW OF PRODUCT GASES THERETHROUGH AND THE SLAG DISCHARGE EXIT BY A WATER SEAL, ADJUSTING AND ARRANGING SAID SLAG DISCHARGE EXIT AND SEAL BELOW THE COMBUSTION ZONE TO PERMIT UNOBSTRUCTED FLOW OF MOLTEN SLAG INTO SAID WATER SEAL, AND DISCHARGING SUFFICIENT PRODUCT GAS THROUGH THE SLAG DISCHARGE EXIT TO KEEP THAT EXIT HOT AND FREE OF SLAG PLUGS.
