ABSTRACT:
A cupola for the melting of metal is provided with an auxiliary gas generator which supplies through the forehearth hot carbon monoxide rich gas to the bottom of the cupola as a source of heat. The heat of the gases maintains the cupola hearth and forehearth hot. Ordinary coal, or coke breeze or any other carbonaceous fuel may be burned in the generator. Additionally, the cupola may be allowed to go to zero output without cooling off.
