Heat exchanger
The water is forced through a heating coil by the high pressure pump. Heating coil: 38 m
long - Content: 5 l of water - Heating capacity: max. 90 kW
The fuel pump draws the oil from the tank through a filter and pumps it to the injector
nozzle. The oil pressure is shown on the fuel manometer.
The heat exchanger is heated by a high pressure fan heater.
A ventilator draws in the cold, fresh air from the bottom end of the machine and forces it
upwards between the outer mantle and the inner mantle. In the process, the fresh air is
pre-heated and the outer mantle of the heat exchanger is cooled.
The pre-heated air is pressed through a mixing unit. Here finely atomized fuel is injected
via a nozzle and mixed with the air. The electrodes located below then ignite the fuel-air
mixture.
The flame burns from top to bottom, turns round and the hot gas flows past the heating
coil on its way back up. The burned gases collect in the exhaust chamber and are emit-
ted from the chimney.
