PURPOSE:To shorten ignition time and ignite surely burning devices without continuous high temp. condition in them by storing a constant amount of fuel under pressure and ejecting it from nozzles for igniting at the ignition starting time. CONSTITUTION:An accumulator 12 is installed at a part 2a between a flow control valve 4 and a shutoff valve 5 in a main fuel supply line 2 and in this accumulator a constant amount of fuel is stored before ignition. At the moment the shutoff valve 5 is opened at the ignition starting time, fuel stored in the accumulator flows under high pressure to fuel nozzles 7-1, 7-2,...7-n by means of the inner pressure of the accumulator 12 and is ejected from each nozzle in a peak condition. Thus, it is possible to eject a constant amount of fuel in a very short time by using the accumulator. Since an accumulated amount of ejected fuel is restricted physically by the volume of the accumulator, continuous high temp. condition in combustion devices are avoided under any condition. |
