Claim 2

IN THE PROCESS FOR THE GENERATION OF POWER FROM A SOLID CARBONACEOUS MATERIAL WHEREIN SAID MATERIAL IS SUBJECTED TO COMBUSTION AT A SUPERATMOSPHERIC PRESSURE AND RESULTING HOT PRODUCTS OF COMBUSTION USED AS WORKING FLUID IN A GAS TURBINE, THE IMPROVEMENT WHICH COMPRISES FORMING A FLUID SUSPENSION OF PARTICLES OF SOLID CARBONACEOUS MATERIAL IN A VAPORIZABLE LIQUID, PASSING THE SUSPENSION AT AN ELEVATED PRESSURE TO A HEATING COIL AS A CONFINED STREAM IN TURBULENT FLOW WHEREIN IT IS HEATED TO A TEMPERATURE AT LEAST SUFFICIENT TO VAPORIZE THE LIQUID AND FROM A DISPERSION OF SOLID CARBONACEOUS MATERIAL IN A VAPOR, SUBJECTING SAID DISPERSION TO COMBUSTION AT SUPERATMOSPHERIC PRESSURE, AND PASSING RESULTING HOT GASES FROM SAID COMBUSTION ZONE TO A GAS TURBINE AS WORKING FLUID FOR SAID TURBINE.

Claim 3

POWER GENERATING APPARATUS COMPRISING, IN COMBINATION A GAS TURBINE; A GAS GENERATING FURNACE CONNECTED TO SAID TURBINE; MEANS FOR SUPPLYING COMBUSTION SUPPORTING FLUID TO SAID FURNACE; MEANS FOR PREPARING A FLUID SUSPENSION OF PARTICLES OF A CARBONACEOUS FUEL IN A VAPORIZABLE LIQUID; AN ELONGATED TUBE HAVING DIAMETER AT LEAST THREE TIMES THE DIAMETER OF THE LARGEST OF SAID PARTICLES, SAID TUBE HAVING AN ENTRANCE CONNECTED TO SAID LAST-NAMED MEANS AND AN EXIT CONNECTED TO SAID FURNACE; AND MEANS FOR HEATING SAID TUBE TO A HIGH TEMPERATURE TO VAPORIZE SAID LIQUID DURING PASSAGE THROUGH SAID TUBE AND FORM A FLOWING DISPERSION IN VAPOR OF DISINTEGRATED PARTICLES OF SAID CARBONACEOUS MATERIAL, SAID LAST-NAMED MEANS COMPRISING MEANS FOR PASSING HOT EXHAUST GASES FROM SAID TURBINE IN HEAT EXCHANGE RELATIONSHIP WITH SAID TUBE.

Claim 4

POWER GENERATING APPARATUS COMPRISING, IN COMBINATION A GAS TURBINE; A GAS GENERATING FURNACE CONNECTED TO SAID TURBINE; MEANS FOR SUPPLYING COMBUSTION SUPPORTING FLUID TO SAID FURNACE; MEANS FOR PREPARING A FLUID SUSPENSION OF PARTICLES OF A CARBONACEOUS FUEL IN A VAPORIZABLE LIQUID; AN ELONGATED TUBE HAVING DIAMETER AT LEAST THREE TIMES THE DIAMETER OF THE LARGEST OF SAID PARTICLES, SAID TUBE HAVING AN ENTRANCE CONNECTED TO SAID LAST-NAMED MEANS AND AN EXIT CONNECTED TO SAID FURNACE; AND MEANS FOR HEATING SAID TUBE TO A HIGH TEMPERATURE TO VAPORIZE SAID LIQUID DURING PASSAGE THROUGH SAID TUBE AND FORM A FLOWING DISPERSION IN VAPOR OF DISINTEGRATED PARTICLES OF SAID CARBONACEOUS MATERIAL, SAID LAST-NAMED MEANS COMPRISING MEANS FOR PASSING HOT EXHAUST GASES FROM SAID TURBINE IN HEAT EXCHANGE RELATIONSHIP WITH SAID TUBE.
