GENERAL
Ariterm’s bio-burners meet the most up-to-date operational and safety standards for the
burning of bio-fuels. The Multijet is a burner equipped with a moving grate which is installed in
the burner compartment of the boiler’s fire chamber. The burner grate is located entirely inside
the fire chamber.
An automation system controls the burner by feeding it fuel and combustion air. The air is
divided through separate fans into primary and secondary air, and the fuel is gasified in the
burner’s grate. The feed system may consist of one of more feed augers and a fuel storage. The
augers and storage are selected according to the fuel being used. The movement of the grate can
be separately adjusted to suit each kind of main fuel.
Between the augers in the multi-auger systems is a sensor, which monitors the fuel feed to the
burner. If a walking floor storage unit is part of the equipment, the automation system also
controls this. When using pellets as fuel, no special control is required for the silo.
The burner’s automation system controls the equipment based on the boiler’s water temperature
which is measured by a PT-100 sensor (with 4...20 mA transmitter). With the Arimatic control
unit (AM200, AM1000, AM2000 or AM3000), the burner can be maintained on constant
partial power settings and reverts to its inactive mode only when the power requirement falls
below the minimum level. In normal operation, the automation system runs the burner based
on the power requirement at a level between 21% and 100%.
The equipment must have burn back protection. Such equipment varies depending on the
fuel and feed system selected. Please note that the fuel selected also affects other parts of the
equipment.
ALWAYS CHECK WITH THE PRODUCT SUPPLIER ON THE SUITABILITY OF
THE FUEL FOR YOUR BURNER!
