For the backyard refiner the very best way to pyrolyze IC chips is to do it in a gas fired smelting furnace
That is because doing it by any other method you do not burn up all the toxic gases produced in pyrolysis
Even if "other" methods produce no smoke - it does not mean that all the toxic gases are being destroyed (burned up)
Little or no smoke only means most of the hydrocarbons are being burned up - but - it does not mean the other toxic gases produced in pyrolysis are being destroyed - they are not
The toxic gases I am talking about are the dioxins & furans produced in the pyrolysis of epoxy IC chips
To destroy those toxic gases during pyrolysis you need 4 thing to take place --- temperature - retention time - oxygen mixing & turbulence
With other (backyard) methods you may get the temp & retention time (which is why you see little or no smoke as the hydrocarbons are burned up) but you likely wont get the proper oxygen mixing & turbulence to destroy the dioxins & furans --- also - the oxygen mixing & turbulence works at destroying most all of the acidic fumes produced during pyrolysis (fumes being different the gases)
In other words - burning up the hydrocarbons (the smoke) is not the only concern in the process of pyrolysis
With a gas fired furnace the furnace provides all 4 of elements needed for good destruction of not just the hydrocarbons - but - the gases & fumes as well

In this thread I have posted pictures of me using my furnace to pyrolyze chips -----------

For what it is worth - I used to process a batch of 40 - 60 pounds of chips per month (so plus/minus 600 pounds a year)
So I have posted a great deal of info on processing IC chips (as have others) so if you want to take a "deep dive" into the process(es) here is a link to more info using incineration as a search word with my user name (kurtak) for the search

That should keep you busy reading for awhile - if you really want to learn about processing IC chips
LOTS of very good info posted not only by me - but - by others as well
