Description

air heating gas burner

technical field

The utility model relates to a burner, in particular to a burner used on a common Chinese frying stove.

Background technique

At present, the burners of ordinary Chinese frying stoves used in large, medium and small restaurants in my country have the following shortcomings:

1. The commonly used burner is to feed in the gas while using the blower to force the air in. The gas in the combustion chamber is not completely combusted and the atomization is not good. Some of the gas is taken away by the high-temperature flame, which pollutes the air and takes away a lot The heat taken away by the high-temperature flame accounts for about 20%-30% of the total heat supplied by the gas.

2. The furnace ring on the upper part of the burner of an ordinary Chinese frying stove has an opening to let 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 about 10% of the gas supply. About 20%-30% of the total calories.

3. The furnace ring on the upper part of the burner of the ordinary Chinese frying furnace has no opening, and must be opened in the furnace, so that the part of the incomplete combustion gas and the remaining flame can be used to heat the auxiliary furnace, and the heat taken away is also about the total heat supplied by the gas. About 20%-30% of that.

From the above three points, it can be explained that the combustion method of ordinary frying stoves, firstly, causes insufficient combustion of gas and seriously wastes resources, and the discharge of unburned gas into the air also pollutes the air. The consumption of gas is increased, and the temperature of the surrounding environment is increased. Insufficient combustion causes carbon monoxide and nitrogen oxides to seriously exceed the standard, which deteriorates the operating environment of the kitchen and directly endangers the health of kitchen operators.

Therefore, people have improved the burners of ordinary frying stoves. The improved burners are roughly divided into two categories: one is to modify the furnace core of the burner, and the original Chinese-style furnace ring remains unchanged. The improved structure of this type of burner is unreasonable. , so that its service life is shortened, and the effect of energy saving after improvement is not obvious. The other type is to refit an electronically controlled energy saver on the basis of the original Chinese frying furnace, which is called a boiler start and stop device. Its energy saving is 20 % or so, because it is an electronic sensor, it will fail after a period of time. People use this type of improved burner and cannot get the economic benefits to be obtained, and are gradually eliminated by the market.
