Abstract
An industrial heating furnace wherein heat in exhaust gases is transferred to combustion air for burners in the furnace through a rotary ceramic heat exchanger. In one embodiment, turbulating air pipes are positioned in the furnace and the heated combustion air is supplied to the turbulating air pipes as well. The turbulating air pipes may be juxtaposed to and positioned across an elongated heating chamber. Liquid fuel in atomized form can be injected into the heated combustion air upstream of the burner.
