ABSTRACT:
A zone controlled furnace for heat-treating of metallic and non-metallic stocks positions one or more modular metallic combustion burners in the furnace chamber and along the path of the stock to selectively control the heat supplied to any zone of the furnace chamber. The burners receive and ignite a high pressure premix of combustible gas and are illustrated by a porous fiber metallic sheet and a jet burner arrangement which discharge flames direct, and a jet nozzle which discharges heated combusted products. The high pressure/velocity flame and products of combustion ejecting from the burners will impinge on the workpieces and generate a very high convective heat transfer rate in a turbulent flow, as well as radiant heat, thereby resulting in uniform heating of non-uniform shaped pieces and maximizing overall heat transfer in the furnace. The apparatus can be controlled to act in a heating mode, or in only a cooling mode, or a combination of modes in any zone for precise temperature control.
