Furnace end for outdoor heater

Abstract

The technical scheme of the invention is to provide a furnace end for an outdoor heater, which has the following structure that: the furnace end comprises a furnace plate and a gas inlet tube, wherein the furnace plate is provided with a plurality of burning channels and a gas collection region; the burning channels are communicated with the gas inlet tube through the gas collection region; and each burning channel is cambered. Therefore, the backflow impact force of fuel gas in the burning channel can be effectively reduced so as to greatly reduce the probability of backfire of the furnace end and ensure full burning of the fuel gas and more stable work and higher safety of the furnace end.

Description

Technical field: [0001] The invention relates to a burner of a combustion device, in particular to a burner for outdoor heaters using combustible gas as fuel. Background technique: [0002] In the prior art, a series of linear combustion holes are provided on the stove of the stove head used for outdoor heaters. These combustion holes are distributed radially outward along the circumference of the stove. All are equipped with a gas gathering area. The combustion holes are connected to the intake pipe through the gathering area, and the center line of the combustion holes generally intersects the axis of the stove. Gas and air enter the gathering area from the intake pipe, and the gas and air are in the gathering area. The zone is mixed, and then enters the combustion tunnel on the furnace head and sprays and burns from the combustion tunnel. This kind of burner also has the following problems in the process of use: the linear combustion channel has poor wind resistance and is pr...

AI Technical Summary

Problems solved by technology

This kind of burner also has the following problems in the use process: the wind resistance of the straight-line combustion channel is relatively poor, and it is prone to backfire phenomenon, that is to say, when the pressure of the gas in the combustion channel is lower than the pressure of the outside air, the flame will The transmission speed is greater than the flow velocity of the gas in the combustion channel, and the linear combustion channel is easy for the flame to flow back into the combustion channel, so that the combustion can be carried out in the combustion channel

And tempering will not only cause insufficient combustion of the gas, affect the stable operation of the burner, but also cause popping and noise, and even explosion, which is less safe. When the flame is straight and long, it is prone to insufficient gas combustion. From the appearance of the flame, the flame tip area turns yellow and the center part turns green, which makes the toxic CO content in the flue gas relatively high, which is easy to harm the user. cause some damages
