ABSTRACT:
A method and apparatus is disclosed for heating metal billets or other separate pieces of metal in a continuous furnace using two different burner systems. The primary burner system provides the majority of available heat at relatively high flame temperatures. The secondary high velocity burner system extrains how furnace products of combustion that impinge around on the load. Thus, heat transfer and temperature uniformity is improved by forcing hot gases between the metal pieces.
