Abstract
A high temperature gas fired heat transfer system ideally suited for melting metals is disclosed. The system generates a heated, reducing furnace atmosphere which prevents formation of metal oxides when the metal is melted. A unique arrangement is provided to draw a portion of the reducing atmosphere from the furnace and combust the drawn furnace atmosphere with high speeds jets of preheated combustion air which convectively impinge and heat the surface of an object to a super heat temperature. That surface is then moved into the furnace enclosure to indirectly heat by radiation and melt the metal at high throughput rates.
