PURPOSE:To improve the ignition property of the combustion equipment by a method wherein an igniter is faced against an ignition port, which is arranged within a gas chamber at the side apart from the air holes of a burner head, in the combustion equipment equipped with the gas chamber, in which gas holes are provided so that the blowing-off direction of the gas holes is nearly normal to that of the air holes of the burner head. CONSTITUTION:At the start of the equipment, liquid fuel is supplied from a fuel pipe 19 into the gas chamber 17 of a burner body 4, which is heated with a preheater 5, in order to convert the fuel to vaporized fuel. On the other hand, combustion air is sent from a blower 1 through air flow straightening holes of an air flow straightening plate 6, a small gap 11 and primary air holes 9 into the gas chamber 17 so as to be brought into contact with said vaporized fuel in order to form gas mixture. At this time, a part of the gas mixture produced in the gas chamber 17 is jetted through the gaps 13 and 13' of a gas flow straightening plate 12 from gas jetting holes 15 and the ignition port 11 into a combustion chamber 18. After that, the gas mixture jetted out of the ignition port 16 is turned to ignitable gas mixture by being added with the air from secondary air holes 10 and ignited and burnt by the igniter 20 arranged above and facing the ignition port 16. |
