Abstract

266,765. Goldsbrough, R. E., and Goldsbrough Patents Co., Ltd. Sept. 1, 1925. Vaporizing-apparatus.-Gas is generated from liquid hydrocarbons by forming a mixture of the hydrocarbon with an atomizing agent, and introducing a decarbonizing agent such as steam into the mixture which is then allowed to expand and is passed through heated passages which may have a catalytic action, the resulting gas being led to a burner or gas-holder. Oil from a pipe 6 is heated in a steam heater 5 and passed by a pipe 7 and valve 24 to nozzles 15 delivering into a fanshaped mixing chamber 2 to which steam is supplied from a pipe 25 and central nozzle 16. Each nozzle 15 comprises a cylindrical casing 18 containing a member 27 the central portion 28 of which is a close fit and serves as a piston, one face 33 of which is subject to the oil pressure and the other face 34 to steam pressure, a spring 87 of adjustable tension pressing the conical end 36, in which is a steam discharge opening 20, against the seating 19 in the chamber casing 14. When the oil and steam valves 24, 26 are opened, the mixed fluids flow into the mixing chamber 2, but when the valve 44 of the central nozzle 16 is opened the pressure on the member 27 is relieved and the oil inlet between the conical end 36 and 19 is widened so that the amount of steam supplied to the chamber 2 can be increased until a surplus of steam is present. The mixture then enters an expansion chamber 57 leading to a gasifying chamber 3 formed by conical members 46, 47, external ribs on the member 46 engaging the member 47 to form a spiral passage 3. The members 46,47 are made of chromium-nickel alloy and exert a catalytic action preventing the deposition of carbon and promoting the formation of methane. The gas is led by a pipe 58 to a burner nozzle 60, a pipe 61 leading to a gas holder. Air for combustion is supplied through louvres 64 in a casing 62 and a further supply is admitted through adjustable openings 74 in a ring 72. Specifications 215,801 and 226,676 are referred to.
