1.3 Operating range
The operating range of an oil burner describes the maximum combustion
chamber pressure depending on the oil mass flow. The operating ranges
were determined on a test boiler according to DIN EN 267:1999-11 and
refer to an altitude of 100m above sea level as well as to a room tempe-
rature of 20°C. The maximum achievable combustion capacity for devia-
ting marginal conditions depends on the start-up resistance of the furnace
which is influenced by the geometry of the combustion chamber, the heat
exchanger as well as the exhaust gas system.

2. Functional description
Oil burners HL60 A/B/E/F are designed as atomising burners with nozzle
mixing for the operation with EL heating fuel. The burner motor operated
with constant speed drives the fuel pump and the combustion air blower.
The fuel pump is designed as a gear pump delivering a continuous fuel
mass flow from the suction side to the pressure side. From there, part of
the fuel flows through a magnetic valve which is integrated in the pump
housing to the injection nozzle. Another part of the fuel is returned
through a pressure control valve to the suction side of the pump. The
injected fuel mass flow is calculated from the size of the nozzle and the
injection pressure set at the pressure control valve (5 bar<pi<18 bar). A
throttle unit is provided for the adjustment of the air volume flow to the
injected fuel mass flow. During burner operation and prior to each burner
start-up, fuel is heated in an oil pre-heater to a temperature of approxi-
mately 70°C. Through this process, fluctuations of fuel viscosity due to
temperature and quality which have an effect on the spraying process
and the fuel flow rate are decreased. The fuel spray is ignited by an elect-
ric spark that is formed by the application of high voltage between two
igniting electrodes. The function of each sub-system will be explained in
detail in the next chapters.
2.1 Mixing device
A yellow flame burner mixing device is used to burn the mixture. The main
components of the mixing unit in the burner tube include the baffle plate
which is firmly connected with the axially adjustable nozzle block and the
oil pre-heater and the spray nozzle which are also screw-connected with
the nozzle block.
