Problems solved by technology

The gas consumption of this burner is high due to the limited ability to mix fuel and air at low pressure
Moreover, the existing gas nozzle elements are usually directly fixed on the burner, so once the nozzle element is selected and fixed on the burner, it is difficult to adjust or replace the nozzle element
This results in a standard burner equipped with a fixed gas nozzle delivery system that cannot be adjusted and changed according to consumer needs, for example, changing the aperture size of the gas nozzle to control the height and temperature of the combustion flame in the burner

Abstract

The present invention discloses one kind of fuel injecting device and relates to fuel gas providing technology for combustion apparatus. The fuel injecting device includes one injection valve, one nozzle element and one bonnet to the injection valve. The injection valve includes one valve body, one inlet end, one outlet end and one central passage between the inlet end and the outlet end; and the nozzle element set to the outlet end of the injection valve has one jet hole in the middle part with inner diameter smaller than that of the central passage in the injection valve. The size of the jet hole is proper for jetting the fuel through the outlet end of the injection valve to the mixing chamber inside the bonnet to control the fuel consumption. Several nozzle elements of different sizes of jet hole are provided for the user to select and to reach clean efficient combustion effect.

Description

【Technical field】 [0001] The invention relates to a gas supply system for gas combustion equipment, in particular to a fuel injection device for combustion equipment using high-pressure mixed gas such as liquefied propane and compressed natural gas. 【Background technique】 [0002] Campers and housewives use portable burners, stationary fireplaces or fire pits indoors and outdoors to heat, cook and enjoy beautiful campfires and fireplace fires. In addition, portable and stationary burners that use compressed gases such as canned or piped propane, natural gas, etc. are often used for cooking and heating in the field, in residential and commercial buildings. In order to meet the combustion and heating requirements, this kind of burner requires a large amount of gas consumption. For example, liquefied propane burners in the form of portable stoves, barbecue grills, household stoves, etc. generally include a low pressure regulator with a nozzle to deliver gas to the stove at low...
