ABSTRACT:
An improved method and apparatus for cooling the under-car channel of a tunnel kiln while minimizing migration of air between the above-car and under-car channels involves controlling or equalizing the mass flow of cooling air directed through the under-car channel and in particular through individual undercarriage cooling zones which can match individual heating zones of the tunnel kiln.
