For high temperature industrial furnaces, recuperators are valuable tools for increasing furnace efficiency. Up to
seventy-five percent (75%) of the available energy in the fuel may be carried out of the furnace in the waste gas,
therefore, heat recovery is essential for fuel conservation and economical operation. By recovering heat from the
hot waste gas exiting a furnace and transferring it to the combustion air feeding the burners, fuel usage can be
reduced by as much as fifty percent (50%). With fuel costs rising, recuperation is certain to play a vital role in
the future.
