Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Such as Figure 1-Figure 3 As shown, a pre-premix burner for commercial gas stoves includes a control valve group, a PWM blower 3 equipped with a Venturi premixer 4, and a burner 6, wherein:

[0026] The control valve group is composed of a pressure stabilizing valve 1 and a zero-pressure main gas solenoid valve 2. The inlet of the stabilizing valve 1 is connected to the gas inlet pipe, and the outlet of the stabilizing valve 1 is connected to the zero-pressure main gas solenoid valve 2 through the pipeline. The inlet end of the zero-pressure main pipe gas solenoid valve 2 is connected to the inlet end of the PWM fan 3 through a pipeline, and the outlet end of the PWM fan 3 is connected to the gas valve 5 at the inlet end of the burner 6 through a pipeline. Venturi premixing The inlet port of the Venturi premixer 4 is connected to the external e...

Abstract

The invention discloses a front pre-mixing combustor used for a commercial fuel gas stove. The front pre-mixing combustor comprises a stove head, an ignition needle, an ion needle, a fuel gas valve, aPWM fan, a Venturi pre-mixer, a zero-pressure header tube fuel gas solenoid valve, a pressure stabilizing vale, a commercial fuel gas stove front pre-mixing controller. The front pre-mixing combustoradopts a front pre-mixing type technology for completely mixing fuels with air before the fuels and the air enter a spray nozzle of a stove head combustion chamber, so that gas molecules are sufficiently stirred and mixed, and therefore, mixing is more complete, combustion speed is not limited by physical conditions such as gas diffusion velocity, combustion speed is higher, efficiency is higher,and emission of harmful CO in smoke gas is reduced. And meanwhile, an automatic pre-mixing technology is applied, so that mixing is guaranteed to be relatively precise. The front pre-mixing combustorguarantees working safety, and is free of phenomena such as flame-lifting, flame-floating and tempering.

Description

technical field [0001] The invention relates to the field of commercial gas burners, in particular to a pre-premix burner for commercial gas stoves. Background technique [0002] With the continuous development of society, people's requirements for improving the living environment are gradually increasing. Clean fuels such as natural gas and liquefied petroleum gas have the characteristics of high combustion efficiency and clean combustion, which are recognized by people and paid more and more attention by the society, and are used more and more widely. And because more and more gas-using projects are being carried out, my country's gas application industry is in an important period of development. my country's gas consumption is huge, which makes the demand increase year by year, with an average annual growth rate of 10%-13%, and the gas industry has a certain gap in supply. At the same time, in order to improve the environment and deal with climate warming and other issu...
