Static hearth incinerator

The combustion of fumes/gas/liquids does not generate much ash and therefore a static hearth incinerator can be used.Liquid waste is pumped straight from the tanks to the incinerator. The plant looks as follows :

1. A static hearth combustion chamber

In which the residence time is 2 sec at 1100 or 1200 Degr.C (depending on the halogenides content of the waste) .The incinerator is equipped with a start-up and support  (pilot) burner on natural gas and a liquid waste injection system equiped with compressed air atomisation. The waste feed stock has to be blended such that the chlorine content of the mix does not exceeded 2% (in mass) ,when using a dry scrubber.(A wet flue gas scrubber can handle up to 30% of Chlorine,thus no blending is required)

2. A flue gas cooling system.

To drop the temperature from 1100 Degr.C down to max.200 Degr.C.The system may consist of a heat recovery system (steam,thermal oil,hot air,etc) or of a flue gas quenching or as a combination of any.

3. An activated carbon dosing system

For abatment of dioxins and furans

4. A sodium Bi-Carbonate injection and dosing system

For the neutralisation of acid components in the flue gas.

5. A dry filter (bag house)

The bag house is equipied with Teflon sleeves and an automatic fly ash extraction system .

6. An induced draft fan

The speed controled fan regulates the flow in the system

7. A stack

App. 30 m. high

8. A control system

For all process control by PLC
