BURNER SEQUENCE CONTROLLERS

A gas burner is a device that is used for mixing a gaseous fuel with oxygen and feeding this mixture to an outlet where it gets ignited and forms a stable combustion front.
The invention of the gas burner increased the use of gas sharply. The fuel gases which were initially used for lighting street lights started being used for a lot of different purposes. This increasing number of uses also led to several new construction patterns and design principles.
Types of Burners
Based on the pressure of the gas that is applied to the burner, burners can be classified into the following types:

• Low-Pressure Burners: The pressure of the gases that are applied to the low-pressure burners are up to 5-kilo Newtons per square meter (kN/m²) or 0.05 kilogram-force per square centimeter (kgf/cm²)
• Medium Pressure Burners: The pressure of the gases that are applied to the medium pressure burners are between 5 to 300-kilo Newtons per square meter (kN/m²) or 0.05 to 3.0 kilogram-force per square centimeter (kgf/cm²)
• High-Pressure Burners: The pressure of the gases that are applied to the low-pressure burners are more than 300-kilo Newtons per square meter (kN/m²) or 3.0 kilogram-force per square centimeter (kgf/cm²)

The main components or parts of a burner are:

The Mixer: The mixer is the part of the burner where the mixing of the fuel gases and oxygen takes place and feeds it to the outlet, i.e the nozzle.
The Nozzle: The nozzle is the outlet of the burner through which the feeded mixture is ignited and forms a stable combustion front.
