Diesel/petrol burner

The processing of the fuel-air mixture and the actual com-
bustion take place in the burner. The fuel flows into the pre-
heating chamber with the shut-off valve opened, where it is
at first heated up. After exiting from the fuel needle, it is
atomised in a venturi nozzle through which primary air
flows. Additionally directed secondary air is routed into the
combustion chamber via the heat shield. The pilot flame is
ignited on the hot spot of the glow plug and then, after
slowly running up, leads to the ignition of the flame in the
full load operating mode. In the process, the heater is
dependent on the most bubble-free fuel delivery possible.
The start process differs in different ambient temperatures
ensuring that the heater starts with the minimum of smoke
emission.
