Kiln Connection: Managing Condensation In Tunnel Kilns
Volatile constituents can sometimes condense in the early preheat or early cooling in certain tunnel kilns. At times, the condensates fall on the product and cause dirt defects. Sometimes the condensates are so chemically reactive that it damages the kiln lining by fluxing the refractories in both the preheat and cooling zones. In either case, undesirable precipitation of volatiles can …
