Description of the invention: [Technical field to which the invention pertains] The present invention relates to a gas combustion test, in particular to a large fire gas burner structure for making a gas pressure. [Prior Art] According to the purpose of increasing the firepower of gas burners, in recent years, many gas stoves have begun to collect gas and high-pressure gas as a gas supply method, so that the burners can be fully obtained. Gas gas supply, to enhance the purpose of burning fire, although the use of medium and rolling gas as fuel, can increase the firepower of the burner, in order to quickly fry or cook food, to create delicious dishes, but the use of high pressure Gas as a gas supply to improve the combustion of fire has the following disadvantages: 1. The use of high-pressure gas, the gas supply control is difficult, easy to form a gas supply pipe or a leak of gas, resulting in gas poisoning or The danger of explosion, etc., causes safety hazards in use. 2. As shown in the sixth figure, the general Bunsen gas burner (Bunsen is designed to supply gas to gas, air, premixing efficiency, and a certain proportion, while using high pressure gas as gas supply, The surge in gas flow rate will result in uneven gas-air mixing or a decrease in mixing efficiency, which will greatly reduce the air (oxygen) content in the gas, resulting in incomplete combustion, not only wasting energy, but also more likely to cause carbon monoxide poisoning. According to the theory of laminar combustion of thermodynamics, if the gas supply rate is greater than its combustion rate, it will cause unstable combustion, so use high pressure gas as gas.
