VERTICAL BURNER FOR GAS EQUIPMENT

摘要

PURPOSE:To provide a small-sized equipment, improve a flame power and further improve a convenience in use of the equipment by a method wherein a burner nozzle ha a structure which is metered to a specific hole diameter for use in injecting fuel gas under a specified secondary pressure, formed at either one or both of floors where a base part of a mixing pipe and the mixing pipe as an air feeding means for feeding air into the mixing pipe and it has a feeding hole for air sucked with the fuel gas flow injected from the nozzle. CONSTITUTION:When a knob 8 is operated, fuel gas advances under a secondary pressure of a maximum of 700 to 1000 mm H2O by a pressure reducing device 7 and then the fuel gas is injected from a burner nozzle 15 at a high speed into a mixing pipe 5. As a result, a strong negative pressure suction flow directed upwardly of the pipe is generated at a base part of the mixing pipe, thereby a large amount of air are flowed from the first and second inlet holes 12 and 21, mixed with fuel gas near the base part of the mixing pipe 5, resulting in forming a sufficiently and uniformly mixed combustible mixture gas and the mixture gas is flowed out of a flame port of the burner cap 22. In this way, a nozzle hole diameter, i.e. an inner diameter of the throat part 18 is set within a range of 0.5 to 0.7 mm.
