Multi-Chamber Furnaces

In recent years, multi-chamber furnaces have been utilized to process contaminated scrap with higher levels of organic or inorganic content. The system uses a combination of dry hearth and well melter design.

The images at right show the typical arrangement of the two chambers. The dry hearth and charge well are enclosed in the charge chamber. The scrap is charged in this chamber where the organics/coatings are volatilized (removed) from the scrap. The fume extraction fan transfers the hot gases/contaminants to the main chamber for oxidizing and removal. The main chamber holds a pool of hot, liquid metal. The circulating device moves hot metal into/through to the well. The circulated hot metal is the source of heat to melt the scrap charged into the well. This process is very similar to a standard well charged melter…
