Re: Coating formation in Kiln Inlet - Page 3 of 3

2009-11-1  Re: Coating formation in Kiln Inlet It can be very misleading to give advice without knowing all the operating data and details over a longer period. However the high sulphur content over 24 hour period (short term) suggests it is not caused by raw meal/fuel chemistry but by insufficient combustion i.e. reducing atmosphare.
