General Operation
Incineration
Like in every combustion process in incineration it is all about providing optimal conditions for clean combustion.
Most important factors you can control are:
Air
Black smoke normally indicates lack of the oxygen in combustion process, so there is a lot of unburned carbon in the
smoke, and this is what makes it black.
Increasing air settings on the air dumper on the side of the burner will provide better air / fuel ratio, which will also
increase burn rate, but this will only help providing there is not too much waste loaded in the chamber.
Fuel (both diesel oil and waste)
You are supplying fuel to a process through burners (pumping diesel oil), and also through waste loaded into a chamber.
It is very important to have primary burner on, only for a short time, to ignite waste. Once waste starts to burn itself, turn
primary burner off. This will help you to obtain better combustion conditions, and also to save fuel.
Temperature
In case of very flammable waste, lower preheating temperature is suggested, as this will prevent all the waste material to
flash instantly, and too much energy to be released in a very short time.
Burn procedure
Please follow these instructions to define optimal batch size, air settings etc:
Repeat steps 2 - 6 above gradually increasing batch size, in order to define maximum batch size, temperature and air
settings for a clean combustion for each waste type you are dealing with.
Most important is to have main burner on for as short time as possible (only for preheating, and waste ignition - if
needed).
Preheat incinerator using both burners with lower air settings during the preheating (main burner air dumper on 3 –
3,5) to 500 – 850 deg C. For highly flammable waste use lower preheating temperature (I.E. 350 - 400 deg C)
Stop primary burner and load small quantity of waste for a start (i.e. 5-15 kg – depends on waste type)
Start primary burner only for a short period of time (i.e 1 minute), but only if waste hasn’t ignited itself - in most
cases you will not need primary burner at all after preheating (if burning flammable waste), and increase air settings
positioning air dumper on main burner to between 6 and 8 (depends on waste type).
Turn main burner off, and If needed, add more air (increase air dumper setting on main burner).
Once waste is ignited, temperature will increase to a certain pick (depending on waste amount and calorific value)
and then, it will start decreasing (indication that it has been mostly burned).
You can now load another batch of waste (a bit more waste than in first batch) etc ...
