KILN HEAT UTILIZATION

Apr 02, 2009 · Re: KILN HEAT UTILIZATION. This is an idea that has been raised periodically. A potential problem is the refractory lining of the kiln relies on the cooling effect of the atmosphere and shell to create a temperature gradient through the lining. If the cooling affect of the shell and atmosphere are compromised by heat exchangers then the life of ...
