Abstract
A regenerative firing system is disclosed which functions in a heat treating furnace or other high temperature technology. The system comprises a plurality of regenerator heat transfer boxes which absorb the heat contained in high temperature exhaust from the furnace. Each regenerator box transfers this absorbed heat to a flow of ambient air. The now heated air flows from the regenerator box into a common air stream which is then fed to a plurality of burners. The preheated air stream is supplied to a common air stream that is then simultaneously provided to each of a plurality of burners. In addition, the current invention comprises a method of heat recovery for a furnace utilizing the inventive system.
