ABSTRACT:
A furnace, particularly for use in a slagging pyrolysis system for the disposal of solid waste, includes a metal hearth portion, unprotected by refractory material, the hearth portion having a plurality of heat conducting studs affixed to the inner wall of the hearth portion and means for cooling the studs for causing a slag coating which protects the hearth wall from attack by corrosive substances, minimizes additional heat loss and prevents melting of the hearth wall.
