The fully premixed surface combustion low-fire burner is provided with a connecting end, which is connected to an air inlet interface and an air inlet interface, so that the gas and air can be fully premixed before combustion, so that the combustion is more complete, thereby improving the combustion efficiency. This combustion method can reduce chemical incomplete combustion and reduce the emission of harmful substances in the exhaust gas. Secondly, by reducing the excess air coefficient during the combustion process, the carbon monoxide content in the exhaust gas is reduced, which meets the relevant national emission standards. At the same time, due to more complete combustion, the emission of harmful gases is reduced, which is beneficial to environmental protection. In addition, its efficient combustion also reduces energy consumption and avoids the low-fire burner because the gas and air are not fully mixed before entering the combustion chamber, resulting in insufficient combustion and low combustion efficiency.

Therefore, the flame can remain stable and uniform during the combustion process, reducing the occurrence of local high-temperature areas and making the temperature field more uniform.
