ABSTRACT:
The hot flue gas expelled from a furnace is used to heat air which is supplied to the burners that fire the furnace. The heated air is delivered to each burner through its ceramic burner block rather than through its cast iron burner body so as to avoid the need of making the body out of expensive alloys capable of withstanding high temperatures.
