Abstract
The invention relates to controlled atmosphere heat treating furnaces and particularly to furnaces for bright annealing of copper or its alloys. A new concept is proposed for conserving energy uses by first having a separate atmosphere producing system that fires constantly, independent of the temperature control and secondly having a cooling system that only extracts the excess heat produced by the combustion for atmosphere. In this way the furnace may be maintained at the desired operating temperatures regardless of variation of the work load, yet all of the heat generated by the atmosphere producing device is released within the furnace thereby eliminating unnecessary heat losses.
