Abstract
Transverse sub-chambers are defined beneath a train of kiln cars. Pressure equalization is permitted with respect to the firing chamber thereabove but very little air will actually pass therebetween because there is no other substantial air passageway leading into or out of the sub-chamber. Rather, heat exchange cooling apparatus is employed in each sub-chamber so as to set up convention air currents within the sub-chamber to cool the underside of the kiln car. The heat exchanger units in different sub-chambers are preferably individually controllable so as to provide a controllable degree of undercar cooling as a function of location along the tunnel kiln.
