This is what I was told it was. But I guess I interpreted its meaning. I thought I pyrolyzation was burning something without direct flame, such as a can with a few holes in a pile of coals? and incineration was basically torching it. What do I have wrong?
Look the definition on Wikipedia. These things are basics. And it was discussed here myriad of times before, dozens of same questions with dozens and dozens of same answers.
Depending on what procedure you inted to use, adjust your process. But firstly, GET YOUR APPARATUS STRAIGHT and plan what you are gonna do. And you certainly want to do better than folks in central Africa, who burn car tires just to be able to sell the steel reinforcements
altough sadly, also here where I live many people do practically the same. For sake of convenience, they are putting their health under very serious threat and slowly giving asthma and lung diseases to the children living in the neighborhood. Just a thing to consider, because we know how it is
If you want to process like Kurt, you does not need to incinerate firstly. If you want to direct smelt the ashes, or leach the ashes, you need to fully incinerate the material to zero leftover carbon.
Filler in IC plastic is 99% of times plain silica dust. Silica is white. So any shade of darker gray or even black does say you do not have plain silica in your ash.
Burning things need two things to burn - AIR AND TEMPERATURE. Neat, easy, nothing else. So that´s it - you need to deliver air => oxygen directly to the place where material will be burnt, and you does need to keep temperature above 500°C for burning to proceed smoothly. Otherwise it won´t happen. Period.
Burner use up the oxygen from the air to combust the fuel (MAPP, propane etc.) - so you aren´t delivering enough oxygen to the chips. If you fill them up into the graphite crucible, how the air is supposed to get to the ones on the middle and bottom ?
Use stainless steel strainer or mesh to allow oxygen to get there, do not make high layers of chips to facilitate the air directly to the place where it is needed. Costs like 2 bucks at dollar store. Just make sure it´s stainless.
And third, do not burn out the oxygen in the air in the first place - use regulated temp heatgun instead of burner. Easy, simple, cheap, straightforward. Whole setup here including cost of the heatgun (ca 35euros) cost me under 80 euros. Permanent investment, usable for many other things - furnance also for melting, heatgun for anything around the house. No excuses are legitimate here
it can be done right.
