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.

A process for operating a pyrolysis type thermal decomposition system comprising the steps of: (a) providing a plurality of batch type furnaces, (b) heating waste type materials in a controlled manner in each furnace where said materials produce fumes exhausted through a fume outlet on each furnace

A process for operating a pyrolysis type thermal decomposition system comprising the steps of: (a) providing a plurality of batch type furnaces, (b) heating waste type materials in a controlled manner in each furnace where said materials produce fumes exhausted through a fume outlet on each furnace as said waste materials are decomposed by thermal reaction; (c) providing one afterburner connected to the gas outlet of all of the furnaces for incinerating the fumes produced by said plurality of furnaces when said waste materials are heated in said furnace; and (d) operating said furnaces in a sequentially staged, overlapping manner to produce a generally constant supply of fumes to said afterburner.
