Description

Air heating gas burner

The present invention relates to a burner, and more particularly to a burner for use in a conventional Chinese type frying furnace. Background technique

At present, there are the following shortcomings in the use of burners for ordinary Chinese-style frying stoves in large, medium and small hotels in China:

1. The commonly used burner is forced into the air while the gas is being injected into the gas. The combustion of the gas in the combustion chamber is incomplete, the atomization is not good, some of the gas is taken away by the high temperature flame, and the air is also polluted. The heat, which is taken away by the high temperature flame, accounts for about 20% - 30% of the total heat supply of the gas.

2. The upper part of the burner of the ordinary Chinese type frying furnace has an opening, letting the flame flow out along the wok, otherwise the flame will be extinguished due to lack of oxygen, so the heat taken away from the high temperature flame at the opening of the furnace ring accounts for the gas supply. 20% - 30% of total calories.

3. The upper part of the burner of the ordinary Chinese type frying furnace has no opening, and must be opened in the furnace to allow some of the incomplete combustion gas and the remaining flame to heat the auxiliary furnace, and the heat taken away also accounts for the total heat of the gas supply. 20% - 30% or so.

From the above three points, it can be explained that the burning mode of the common frying furnace, the first makes the gas combustion insufficient and seriously wastes resources, while the unburned gas is discharged into the air and pollutes the air, and the second causes a large amount of heat energy to be lost. The use of gas is increased, and the ambient temperature is raised. The insufficient third combustion causes the carbon monoxide and nitrogen compounds to exceed the standard seriously, which deteriorates the operating environment of the kitchen and directly jeopardizes the health of the kitchen operators.

Therefore, people have improved the burners of ordinary fryers. The improved burners are roughly divided into two categories: one is the core of the modified burner, the original Chinese furnace ring is unchanged, and the improved structure of this type of burner is unreasonable. , the life of the use is shortened, and the effect of energy saving after improvement is not obvious. The other type is converted into an electronically controlled energy saver based on the original Chinese type of frying stove, called the boiler start-stop device, and its energy saving is 20 % or so, because it is electronic induction, it has failed after a period of use. The use of such improved burners does not yield the economic benefits to be obtained, and is gradually eliminated by the market. Summary of the invention
