Kiln inlet gas analysis - field experiences with new probe design

This paper reviews field experience gathered from recent installations of a new a kiln inlet gas sampling system and its new design concept. The system has been installed in the field since 2003 and has been able to provide high run factors with a very low level of maintenance. The success of the new gas sampling system relies on a very simple and rugged design that promotes powerful cleaning cycles. While the system has shown some very impressive run factors, the need for occasional checks and maintenance cannot and should not be completely eliminated. Results have shown that the key to success is simplifying and minimizing these maintenance tasks to maximize run factor and minimize effort.
