Method for gasification of solid fuels

Claim 1

A METHOD FOR PRODUCING VALUABLE GASEOUS PRODUCTS FROM SOLID CARBONACEOUS FUEL WHICH INCLUDES MIXING PARTICLES OF SAID FUEL WITH STEAM WHICH IS UNDER PRESSURE, INJECTING SAID PARTICLES INTO A COMBUSTION ZONE MAINTAINED AT A TEMPERATURE OF FROM ABOUT 2200* TO ABOUT 3500* F., ADMIXING AND REACTING FREE OXYGEN THEREWITH IN SAID ZONE TO PRODUCE MOLTEN SLAG, PARTIALLY BURNED FUEL PARTICLES, AND A GASEOUS MIXTURE COMPRISING CO AND CO2, THE INJECTING BEING EFFECTED AT SUCH VELOCITY AND AT SUCH ELEVATION ABOVE THE FLOOR OF THE ZONE THAT THE PARTICLES OF FUEL AND MOLTEN SLAG FOLLOW AN ARCUATE PATH, DUE TO THE ACTION OF GRAVITY, TERMINATING AT THE FLOOR OF SAID ZONE SHORT OF THE BOUNDARY OF SAID ZONE TOWARD WHICH INJECTION IS EFFECTED, FORMING AT THE BOTTOM OF SAID ZONE A HORIZONTAL QUIESCENT BED OF MOLTEN SLAG HAVING ON THE SURFACE THEREOF PARTIALLY BURNED FUEL ARTICLES, AND THEREAFTER ALLOWING THE LATTER TO REACT WITH CO2 IN SAID GASEOUS MIXTURE TO PRODUCE ADDITIONAL QUANTITIES OF CO.

Claim 2

A METHOD FOR PRODUCING VALUABLE GASEOUS PRODUCTS FROM SOLID CARBONACEOUS FUEL WHICH INCLUDES MIXING PARTICLES OF SAID FUEL WITH STEAM WHICH IS UNDER PRESSURE, INJECTING SAID PARTICLES INTO A COMBUSTION ZONE MAINTAINED AT A TEMPERATURE OF FROM ABOUT 2200* TO ABOUT 3500* F., ADMIXING AND REACTING FREE OXYGEN THEREWITH IN SAID ZONE TO PRODUCE MOLTEN SLAG, PARTIALLY BURNED FUEL PARTICLES, AND A GASEOUS MIXTURE COMPRISING CO AND CO2, THE INJECTING BEING EFFECTED AT SUCH VELOCITY AND AT SUCH ELEVATION ABOVE THE FLOOR OF THE ZONE THAT THE PARTICLES OF FUEL AND MOLTEN SLAG FOLLOW AN ARCUATE PATH, DUE TO THE ACTION OF GRAVITY, TERMINATING AT THE FLOOR OF SAID ZONE SHORT OF THE BOUNDARY OF SAID ZONE TOWARD WHICH INJECTION IS EFFECTED, FORMING AT THE BOTTOM OF SAID ZONE A HORIZONTAL QUIESCENT BED OF MOLTEN SLAG HAVING ON THE SURFACE THEREOF PARTIALLY BURNED FUEL ARTICLES, AND THEREAFTER ALLOWING THE LATTER TO REACT WITH CO2 IN SAID GASEOUS MIXTURE TO PRODUCE ADDITIONAL QUANTITIES OF CO.
