Description

Windproof outdoor stove burner

The invention mainly discloses a stove burner, in particular a windproof outdoor stove burner.

Please refer to the patent case No. 201410258948.7 of the People's Republic of China for a high-power infrared horizontal radiation outdoor gas heater, which discloses a high-power infrared horizontal radiation outdoor gas heater, including a gas bottle The box is equipped with an ignition control device on the box, a universal wheel at the bottom of the box, an opening on the front panel of the box, and at least two independent infrared gas burners are installed at the opening. The infrared gas burner is installed in a horizontal outward radiation direction, and a metal mesh cover is installed outside the opening.

The above heater is mainly used by the user for outdoor use. During use, the gas is mixed in the burner mixing cavity. The pressure in the cavity blows out the mixed gas through the pores of the porous ceramic plate and ignites. The thermal radiation gas burner has directional heating and generates a large combustion area. The high temperature of combustion can produce a large proportion of infrared heat radiation on the surface of the porous ceramic plate burner, so it can provide a high-efficiency radiant heat source. This is essential for use in outdoor environments, as users are immediately comfortable and warm when heated in a solar-like manner when radiant heat is directly irradiated. However, such a burner with a porous ceramic plate has a problem of being easily extinguished. Because the air outlet of the porous ceramic plate is directly exposed to the wind and the area covered by the wind is large, if strong wind or instant gusts are encountered, back pressure is easily formed on the surface of the porous ceramic plate burner. Or create turbulence, which is not conducive to maintaining the conditions required for combustion. The conditions for the combustion of a porous ceramic plate burner include a consistent air supply and a stable and uniform gas mixture concentration. At the same time, a stable pressure must be maintained in the mixing cavity to allow the mixed gas to flow uniformly out of the surface of the porous ceramic plate of the burner at a low speed. In order to maintain normal and stable combustion. When the heater is used outdoors, it is inevitable that it will be blown by the natural wind from outside. If the wind is too strong, the wind pressure and turbulence caused by strong wind or gust often cause the burner to extinguish or fail, and even cause danger. The possible dangers include at least the following two conditions: First, the flame on the burner surface is extinguished by the wind, but the gas control system cannot immediately sense that the flame on the burner has extinguished and continues to supply gas, which will cause gas to accumulate in the heater. Inside or around the heater, when the wind becomes small or stopped, if the heater is re-ignited, the high-concentration gas accumulated in the surrounding area will be ignited at the same time, and instantaneous large-scale flame combustion may even occur. The second is that the strong wind blows directly into the burner's mixing chamber, and pushes the flame into the mixing chamber to form a flashback state. The flashback condition will cause the flame to burn inside the mixed gas box and burn outside the non-mixed cavity, which causes a large amount of heat to be accumulated in the mixed cavity for a moment, causing danger. Since both situations are dangerous, appropriate ways must be found to overcome them.
