The power supply to the incinerator must be turned on immediate after black out. The cooling program...
program of the incinerator will then automatically be activated. In case of a black out of more than 5 to 7
minutes the possibility of damaging the incinerator is very high. In case the emergency switch board is
hooked up to the main supply of the Incinerator, the plant will start at cooling program until it the
temperature reach 100°C and/or until manual reset at the electric panel. Factory settings: The nozzles are
adjusted to max sludge burning capacity, without burning solid waste. This setting can be found by closing
the nozzles and turn them counter clockwise 1/4 round. Adjustment on board: Depending on the layout of
the funnel and depending on the amount and type of solid waste burned, the nozzles might require
readjustment. If no measuring tools are available, please observe if there is coming dark smoke out of the
stack. If so, then open the air nozzles in the primary combustion chamber until it stops.
If the exhaust gas temperature is too high, or if sparks are developed, this can be overcame by opening
the air nozzles in the secondary chamber (left turn more air, right turn less air).
