Natural Gas Burners:
Compared to other fuels, gas fuel is the easiest to burn, and therefore, gas fuel burners have the simplest structure among burner types. The primary task of a natural gas burner is to mix and ignite fuel and air. Additionally, it has functions related to combustion control and safety. Gas burners are divided into two main groups;

Blow-off (Atmospheric) gas burners

Forced-draft (Fan) gas burners

Forced-draft gas burners are further divided into two categories today:

Pre-mix (diffusion flame) forced-draft gas burners

Pre-mixed forced-draft gas burners

Pre-mixed burners are a type of burner developed in recent years and used as an alternative to atmospheric burners. They stand out, especially with low emission values and proportional capacity control, and are primarily used in modern boilers.
