Abstract
Abstract A device for vaporizing the liquid hydrocarbon fuel as it enters a stream of flowing oxygen-containing gas. The device has a fuel feed tube, a Venturi for conducting a stream of oxygen-containing gas past the end of the feed tube, a vaporizable liquid hydrocarbon fuel supply connected to the feed tube, a corrugated heater plate at the end of the feed tube, where it projects into the stream of gas and an electric resistance heater in the plate. A thermostat is electrically and thermally coupled with the resistance heater for controlling the temperature of the heater. Alternatively the corrugated heater plate can be in front of a fuel injection nozzle for a Diesel engine or an oil burner.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
170 words
A device for vaporizing liquid hydrocarbon fuel as it enters a downwardly flowing stream of flowing oxygen-containing gas, comprising a reservoir for a vaporization liquid hydrocarbon fuel, a fuel feed tube extending upwardly out of said reservoir and then laterally, means for conducting a stream of oxygen-containing gas downwardly past the end of said feed tube for drawing fuel through said fuel feed tube, a corrugated heater plate mounted on the end of said feed tube and projecting from the end of the feed tube into the stream of gas and an electric resistance heater in said plate and having a heating capacity for heating the amount of fuel flowing through said fuel feed tube to supply the latent heat of vaporization thereto and heat the fuel to a temperature between a temperature about halfway between the temperature of vaporization and the temperature at which the vaporized fuel becomes explosive in the oxygen-containing gas, whereby the fuel is instantaneously and completely vaporized upon coming in contact with said corrugated plate.
Claim 2
Independent Claim
170 words
A device for vaporizing liquid hydrocarbon fuel as it enters a downwardly flowing stream of flowing oxygen-containing gas, comprising a reservoir for a vaporization liquid hydrocarbon fuel, a fuel feed tube extending upwardly out of said reservoir and then laterally, means for conducting a stream of oxygen-containing gas downwardly past the end of said feed tube for drawing fuel through said fuel feed tube, a corrugated heater plate mounted on the end of said feed tube and projecting from the end of the feed tube into the stream of gas and an electric resistance heater in said plate and having a heating capacity for heating the amount of fuel flowing through said fuel feed tube to supply the latent heat of vaporization thereto and heat the fuel to a temperature between a temperature about halfway between the temperature of vaporization and the temperature at which the vaporized fuel becomes explosive in the oxygen-containing gas, whereby the fuel is instantaneously and completely vaporized upon coming in contact with said corrugated plate.
Claim 3
Dependent Claim
57 words
A device as claimed in claim 1 in which said corrugated plate is mounted on the end of said tube extending at an acute angle to and downward in the direction of the flow of the stream of gas past the end of said tube for causing fuel to flow in a turbulent flow over the corrugations.
Claim 4
Dependent Claim
30 words
A device as claimed in claim 1 in which said corrugated plate extends upwardly across the opening from said tube to have fuel projected from said tube strike said plate.
Claim 5
Dependent Claim
27 words
A device as claimed in claim 1 further comprising a thermostat means electrically and thermally coupled with said resistance heater for controlling the temperature of said heater.
