It will always be our preference that the client pre-incinerates / use of pyrolysis (conditions) the raw e-Waste (printed circuit boards, computer memory etc.) which will allow our plasma smelting furnace to treat a concentrated waste, but increasingly, we are being asked to provide a complete turnkey plant including pre-incineration / pyrolysis of the e-waste.
We require indicative information and a budgetary cost please for an incineration / pyrolysis plant that will handle about 3000 tonnes per year of raw E-waste producing about 2000 tonnes per year of Integrated Circuit (IC) Sweeps. Here we assume about a 30 – 35% weight loss due to the removal of volatiles.
Close the door.
Obtaining the combustion cycle during which no monitoring service ( duration 2 hours ) is required.
The combustion cycle automatically ensures :
Starting the secondary air fan.
After 10 minutes, the afterburner is temperature:
?Turning on the automatic burner combustion chamber , which guarantees the output of the gasification of waste. The operating time of the burner is programmable according to the type of waste, using an adjustable mechanical timer from 1-60 minutes.
Automatic start of combustion air fan.
After 2 hours , the end of ” combustion cycle ” automatically guarantee :
The closure of primary air servomotor .
The post-combustion burner off.
During charging , opening the door automatically ensures immediate shutdown fan primary and secondary air . At the end of the combustion cycle the fan primary / secondary air and burner continues to run for 2 hours to protect the burners and to cool the oven . After this time the program automatically turns off the installation completely .
Ideally, we would like the supplied information to cover material loading/unloading, the incineration / pyrolysis process and the off-gas system (scrubbers etc.). Our understanding is that pre-incineration is conducted to homogenise the waste and to minimise the subsequent losses of species at the smelting stage through the formation of chloride/bromide salts and through oxidation losses, i.e. the halogens being driven off at a lower temperature to that at which the salts/oxides could boil in the smelting stage.
