摘要： Method and apparatus is disclosed for thermally decomposing waste material from several batch furnaces plumbed into one afterburner. The afterburner is modified to mix and combust in a controlled manner an otherwise explosive mixture of fumes from several furnaces. The entire system is regulated only by the temperature of incinerated gases from the afterburner. The furnaces are operated in a sequenced, overlapping staged manner to produce a generally constant fume loading permitting significant cost savings in equipment and operation.

摘要： A semi-continuous pyrolysis arrangement is disclosed which is particularly useful in the reclamation of a base material in a substantially pure form from a composite material which has organic compounds. The furnace base barrier free zones wherein the waste material is continuously pyrolyzed as it is indexed through the furnace and each zone is controlled in a preset manner established from pyrolyzing a sample waste specimen under controlled conditions. Preferably, the waste is containerized as a particulate solid in discrete static beds permitting a fan exhaust arrangement to establish convective heat transfer with the bed while also establishing the furnace zones. An exothermic zone is provided at the end of the furnace to remove fixed carbon from the pyrolyzed waste by bleeding substoichiometric amounts of air in an oxygen temperature controlled manner to permit recovery of the waste in a substantially pure form.
