ABSTRACT:
A method of independently adjusting the fuel mixture composition and heating rate for a multiburner shaft furnace for the melting of metal, particularly copper and its alloys, fed in lump form to the shaft furnace, in which the burners are supplied with air and fuel gas and the heating rate is adjusted by controlling the pressure of one of the components of the fuel mixture (air or gas) in the manifold for supplying this component to a group of burners. The other fuel mixture component has its pressure controlled in its manifold by a single controller constituted by a pressure ratio controller.
