Description

A gas energy-saving burner

technical field

The invention relates to a burner, in particular to a gas energy-saving burner.

Background technique

At present, the gas burners used on the market are divided into two categories: natural air burners and fan combustion burners. Fan burner burners can be divided into premixed burners and non-premixed burners according to their different combustion methods. Due to the premixed combustion method, the ratio of oxygen (air intake) and gas is difficult to grasp, and its thermal efficiency is usually difficult to reach the ideal level. Therefore, the current large-scale catering units generally use non-premixed cylindrical burners ( Commonly known as hook wind stove head: the fire comes out in the middle, and the wind enters around). Although the current hook-up burner burns relatively fully and has relatively large firepower, due to the use of a cylindrical right-angled air intake method, the flames collide with each other with high intensity and high frequency during combustion, resulting in huge noise. At the same time, Because this kind of burner needs to ensure full combustion, not only the space of the furnace is required to be large enough, but also a fan with a power of more than 250W is generally required.

Contents of the invention

The technical problem to be solved by the present invention is to solve the flame collision phenomenon in the combustion process of the existing cylindrical burner, and to provide a gas energy-saving burner with low combustion noise, small wind loss and high combustion efficiency.

The technical solution adopted by the present invention to solve the above technical problems is: a gas energy-saving burner, which includes a combustion chamber, an air inlet pipe connected to the bottom of the combustion chamber, and a main fire inlet that vertically passes through the air inlet pipe and the combustion chamber in sequence. The air pipe, wherein the side of the combustion chamber is provided with an open flame intake pipe, and a wind screen is embedded inside, and a nozzle with an air injection hole is arranged in the air screen, and the bottom of the nozzle is connected with the upper end of the main fire intake pipe, and the feature is that: the combustion chamber shell The shapes of the air screen and the air screen are both conical and matched with each other, and a plurality of air inlet holes are arranged on the air screen.

In order to make the gas energy-saving burner meet the different requirements of different users for combustion firepower, a flow regulating valve is set at the air inlet of the main fire inlet pipe, and an air volume control valve is installed at the air inlet of the air inlet pipe. , so that the combustion firepower can be adjusted by adjusting the gas flow or air intake to meet different combustion needs.

In order to facilitate the discharge of oil, overflow, etc., and to facilitate daily maintenance, a sewage outlet is arranged vertically below the main fire intake pipe.

As a further improvement, plugs or valves can be used to close the sewage outlet to prevent oil, overflow, etc. from dripping into the operating environment, and to avoid natural wind flowing backward from the sewage outlet and affecting combustion.

Compared with the prior art, the advantage of the present invention is that the gas energy-saving burner in the present invention adopts a conical air screen and a matching conical burner, which can make the wind entering from the air inlet pipe along the The air inlet hole of the conical air sieve evenly supplies combustion, so that the main combustion fire enters the normal combustion along the air inlet hole of the conical air sieve in a vertical upward direction, which can avoid the collision of flames during the combustion process and greatly reduce the combustion noise , reduce wind loss, greatly improve gas utilization and combustion efficiency.

Detailed ways

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

As shown in Figures 1 and 2, the gas energy-saving burner in the present invention includes a combustion chamber 1, an air inlet pipe 2 communicating with the bottom of the combustion chamber 1, and a main pipe that vertically passes through the air inlet pipe 2 and the combustion chamber 1 successively. Fire intake pipe 3, wherein the outer surface of combustion chamber 1 is provided with permanent flame intake pipe 4, inside is embedded with wind screen 5, is provided with nozzle 6 with air injection hole 61 in the air screen 5, and the bottom of nozzle 6 is connected with main fire intake pipe 4. The upper ends are connected, wherein the shell 11 of the combustion chamber 1 and the air screen 5 are both conical in shape and match each other, and the air screen 5 is provided with a plurality of air inlet holes 51 . In order to make the burner meet the different requirements of different users for firepower: set a flow regulating valve 32 at the air inlet 31 of the main fire inlet pipe 3; set an air volume control valve at the air inlet 21 of the air inlet pipe 2 twenty two. For the convenience of daily maintenance, a sewage outlet 33 is arranged vertically below the main fire inlet pipe 3, and the sewage outlet 33 can be closed with a plug or a valve.

During use, first open the pilot flame gas valve, the gas enters the area between the combustion chamber shell 11 and the conical air screen 5 through the pilot flame intake pipe 4, and starts the electronic ignition device (or manually ignites) to burn the gas in the combustion chamber 1 The permanent flame is ignited, and the combustion-supporting fan is started, so that the permanent flame enters a normal combustion state in the combustion chamber 1. Then open the main fire gas valve, after the gas enters the nozzle 6 from the main fire inlet pipe 3, it is ejected from the gas injection hole 61 to the combustion chamber 1 along the horizontal direction, and after being ignited by the permanent flame, under the action of the combustion-supporting blower, the main fire is blown along the horizontal direction. The air inlet 51 of the conical wind screen 5 enters into normal combustion in a vertically upward direction.
