Manufacture of water gas

Claim 2

A CONTINUOUS LOW PRESSURE PROCESS OF MAKING WATER GAS AND THE LIKE WHICH CONSISTS IN HEATING FINELY-DIVIDED CARBONACEOUS MATERIAL OF THE CLASS CONSISTING OF PEAT, LIGNITE AND WOOD, IN THE PRESENCE OF OXYGEN TO CHAR THE CARBONACEOUS MATERIAL, PUMPING A STREAM OF SAID CHARRED CARBONACEOUS MATERIAL AT ABOUT 30 FEET PER SECOND, INJECTING SUPERHEATED STEAM UNDER SUPERATMOSPHERIC PRESSURE OF 50 TO 500 POUNDS PER SQUARE INCH INTO SAID MATERIAL TO SUSPEND SAID MATERIAL IN SAID STEAM AND THEREBY RENDEDR THE SAME FLUENT, EXTERNALLY HEATING ABOUT 800 TO 2,000 FEET OF SAID STREAM TO A TEMPERATURE BETWEEN 800* AND 1600* F. AND THROTTLING SAID STREAM TO MAINTAIN IT UNDER A STATIC PRESSURE OF 50 TO 500 POUNDS PER SQUARE INCH.

Claim 3

IN AN APPARATUS FOR CONTINUOUSLY PRODUCING WATER GAS FROM CHARRABLE MATERIALS, THE COMBINATION OF AN ELONGATED COILED CONDUIT, A PUMP CONNECTED TO ONE END THEREOF, A FIRST HOPPER FOR SUPPLYING FINELY-DIVIDED CARBONACEOUS MATERIAL TO SAID PUMP FOR PUMPING THROUGH SAID CONDUIT, A HEAT EXCHANGING COIL IN SAID HOPPER, A BURNER FOR HEATING SAID CONDUIT EXTERNALLY TO CAUSE THE CARBONACEOUS MATERIAL FLOWING THROUGH SAID CONDUIT TO CHAR, MEANS CONNECTING SAID FIRST CONDUIT TO SAID HEAT EXCHANGING COIL FOR FLOW OF SAID CARRED CARBONACEOUS MATERIAL THERETHROUGH TO PREHEAT THE CARBONACEOUS MATERIAL IN SAID HOPPER, A SECOND HOPPER FOR RECEIVING THE CHARRED MATERIAL FROM SAID COI, A SECOND COILED CONDUIT, A SECOND PUMP HAVING AN INLET CONNECTED TO SAID HOPPER AND AN OUTLET CONNECTED TO SAID SECOND COILED CONDUIT FOR DELIVERING SAID CHARRED MATERIAL FROM SAID SECOND HOPPER TO THE INLET END OF SAID SECOND CONDUIT, MEANS FOR SUPPLYING STEAM TO SAID SECOND CONDUIT ADJACENT TO SAID PUMP FOR MIXTURE WITH THE CHARRED MATERIAL PUMPED THERETHROUGH, A SECOND BURNER FOR HEATING SAID SECOND CONDUIT EXTERNALLY, A SEPARATOR CONNECTED TO THE OUTLET END OF SAID SECOND CONDUIT FOR SEPARATING GASES FROM THE SOLID RESIDUE OF THE REACTION, A THROTTLING VALVE INTERPOSED BETWEEN SAID SECOND CONDUIT AND SAID SEPARATOR, AND A SECOND HEAT EXCHANGING COIL IN SAID SECOND HOPPER AND CONNECTED BETWEEN THE OUTLET OF SAID SECOND CONDUIT AND SAID THROTTLING VALVE IN HEAT EXCHANGING RELATION TO THE CHARRED MATERIAL IN SAID SECOND HOPPER FOR HEATING SAID CHARRED MATERIAL PRIOR TO ITS ENTRY INTO SAID SECOND PUMP.

Claim 4

IN AN APPARATUS FOR CONTINUOUSLY PRODUCING WATER GAS FROM CHARRABLE MATERIALS, THE COMBINATION OF AN ELONGATED COILED CONDUIT, A PUMP CONNECTED TO ONE END THEREOF, A FIRST HOPPER FOR SUPPLYING FINELY-DIVIDED CARBONACEOUS MATERIAL TO SAID PUMP FOR PUMPING THROUGH SAID CONDUIT, A HEAT EXCHANGING COIL IN SAID HOPPER, A BURNER FOR HEATING SAID CONDUIT EXTERNALLY TO CAUSE THE CARBONACEOUS MATERIAL FLOWING THROUGH SAID CONDUIT TO CHAR, MEANS CONNECTING SAID FIRST CONDUIT TO SAID HEAT EXCHANGING COIL FOR FLOW OF SAID CARRED CARBONACEOUS MATERIAL THERETHROUGH TO PREHEAT THE CARBONACEOUS MATERIAL IN SAID HOPPER, A SECOND HOPPER FOR RECEIVING THE CHARRED MATERIAL FROM SAID COI, A SECOND COILED CONDUIT, A SECOND PUMP HAVING AN INLET CONNECTED TO SAID HOPPER AND AN OUTLET CONNECTED TO SAID SECOND COILED CONDUIT FOR DELIVERING SAID CHARRED MATERIAL FROM SAID SECOND HOPPER TO THE INLET END OF SAID SECOND CONDUIT, MEANS FOR SUPPLYING STEAM TO SAID SECOND CONDUIT ADJACENT TO SAID PUMP FOR MIXTURE WITH THE CHARRED MATERIAL PUMPED THERETHROUGH, A SECOND BURNER FOR HEATING SAID SECOND CONDUIT EXTERNALLY, A SEPARATOR CONNECTED TO THE OUTLET END OF SAID SECOND CONDUIT FOR SEPARATING GASES FROM THE SOLID RESIDUE OF THE REACTION, A THROTTLING VALVE INTERPOSED BETWEEN SAID SECOND CONDUIT AND SAID SEPARATOR, AND A SECOND HEAT EXCHANGING COIL IN SAID SECOND HOPPER AND CONNECTED BETWEEN THE OUTLET OF SAID SECOND CONDUIT AND SAID THROTTLING VALVE IN HEAT EXCHANGING RELATION TO THE CHARRED MATERIAL IN SAID SECOND HOPPER FOR HEATING SAID CHARRED MATERIAL PRIOR TO ITS ENTRY INTO SAID SECOND PUMP.
