Abstract
Abstract The invention concerns a device for quick starting a reformed gas converter. A first fuel nozzle vaporizes fuel supplied thereto and directs the fuel towards a flame tray. An oxygen carrying gas is combined with the vaporized fuel and the mixture is ignited by a suitable ignition device. The hot gases generated permeate through the device to pre-heat a catalytic converting material such as a perforated sintered block. A second fuel nozzle, after the converting material has been pre-heated to a minimum temperature, directs a stream of vaporized liquid fuel against the heated block. The reform gas generated passes into the reform gas generator proper as fuel therefor. By control of the combustion temperature, the hot gases generated by the ignition step when they pass through the sintered block will also be partially converted to reform gas, suitable for fuel for the generator proper, thereby allowing immediate operation of the generator.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
214 words
A rapid starting device for a reformed gas generator comprising: a. first means for injecting and atomizing liquid fuel supplied thereto; b. a flame dish arranged relative to said first means for injecting and atomizing such that the flame dish will receive atomized fuel from said first means for injecting and atomizing; c. means for supplying an oxygen carrying gas; d. means for igniting the atomized fuel collected in said flame dish to produce hot gases; e. second means for injecting and atomizing fuel supplied thereto; f. a catalyst for the catalytic conversion of liquid fuel, arranged relative to said second means for injecting and atomizing such that the fuel atomized by said second means for injecting and atomizing, is directed toward said catalyst; g. means to conduct hot gases produced in said flame dish toward said catalyst to heat up said catalyst; h. means to couple fuel supply to said second means for injecting and atomizing when said catalyst is heated to the temperature necessary for the fuel to react; and i. means to couple the fuel supply to said first means for injecting and atomizing, said latter means to couple including means to turn off the fuel supply when said fuel supply is coupled to said second means for injecting and atomizing.

Claim 3
Dependent Claim
23 words
The apparatus of claim 1 wherein said catalyst has a carrier said carrier comprising a perforated sintered block having a truncated cone shape.
Claim 4
Dependent Claim
40 words
The apparatus of claim 1 wherein said igniting means further comprise means for defining a chamber wherein said ignition takes place, said chamber defining means also improving combustion of said ignited mixture through reflection of heat back into said chamber.
