There is no mixing chamber, fuel gas and oxidising means are kept
separately up to the burner front plate. Mixing is carried out just in
front of the burner. This principle gives some advantages:
|горелки с внутренним смешением
They work with combustible mixture of fuel gas and oxidant. The mixture is prepared by means of a mixer. Combustion velocity has to be balanced with velocity in the burner nozzles in dependence on the ratio between fuel gas and oxidant. If velocity in the nozzles is lower than combustion velocity than the flame flashes back. In case of perfect adjustment the premix burners give very concentrated and very intensive flame.
