How do gas burners achieve flameless combustion?

In the energy-saving equipment industry, there is a term called flameless combustion. Flameless combustion means that the burner pre-mixes gas and air in a certain proportion to form a combustible mixture before combustion, and then ejects from the gas burner for combustion, which is a power combustion type and can achieve the purpose of environmental protection.

1.Characteristics of flameless combustion

Flameless combustion because the gas and air have been pre-mixed before entering the oil burner, no longer need mixing time in the combustion process, so the total time of the combustion process actually depends on the chemical reaction time; the air coefficient required to complete the combustion of gas is very small, generally 1.05~1.15, or even as low as 1.03~1.05, while the degree of combustion is very high, and its chemical incomplete combustion loss is close to Nearly zero. This combustion method combustion temperature is high, close to the theoretical combustion temperature, combustion flame is short and transparent, no obvious outline, in the background of the hot combustion pit, even can not see the flame, so called flameless combustion.

2.Advantages of flameless combustion

make the burner self-adjusting; simple and reliable mixing device; fast combustion speed, etc.

3.Flameless combustion in industry

Oil burners such as to achieve flameless combustion can be used in a variety of ways, including industrial burner manufacturers widely used is the use of injectors, gas as the injection medium, air as the medium to be injected (in a few cases there are also air as the injection medium), so that the two through the injector to achieve uniform mixing. This device is called jet flameless burner, or simply jet burner.
