Burners, oil and gas fittings

Gas burners are used in industrial and residential buildings for hot water and heating supply. The burner is designed to maintain stable combustion and ensure nearly complete fuel incineration at various loads. Gas burners are easy to install, have a rugged design, and do not produce noise or vibration during operation. The main requirement for these systems is combustion with low emission of poisonous substances. It means that the percentage of harmful gases in the emitted combustion products must not reach the limit values.

All gas burners can be divided into two major groups: atmospheric gas burners and forced draft burners. Atmospheric burners use gas that is mixed with atmospheric air. They are quite simple in design. Gas is fed into the ejector through hollow rods with holes in the upper section. This way gas and air mixture is produced in the combustion chamber. The mixture is ignited by electrodes. Subsequently, combustion process occurs at low temperatures.

The principal design of forced draft burners is different. Air is supplied using air blowers. This ensures that the required amount of fuel mixture is accurately supplied. Normally, forced draft burners are used in boilers equipped with a closed combustion chamber, with a threaded rubber compensator, and operate under pressure. One more sophisticated feature of these burners is extensive process automation. This prevents problems in case of functional failures. The automatic system immediately turns off the burner and blocks its re-start until the error is eliminated.

Apart from their operating principle, gas burners are categorized by their functionality into several types. They can be either multistage or single-stage. This function provides for continuous control of the threaded rubber compensator required for boiler operation.
