Information impactogram application for fast detection of temperature instability zone of a two-channel ceramic roller kiln

A fast procedure for determination of instability zone of a two-channel ceramic roller kiln, Siti type, is proposed. The basis for determination of instability zone is the calculation of code identity of final fallout signal and temperature sensor signal from the roller kiln in relevant critical firing zone. The case of product fallout increase above 6% is used as indicator for procedure application. Code letters for the signals are determined and their respective onedimensional tessellation entropy is calculated. The case of expanded code and entropy congruence can be taken as indicative enough for determination of the firing instability zone from the fallout increase standpoint. The signal s50 temperature zone of two-channel roller kiln was indicated in the period August/September 2009 as responsible for product losses in approximately six consecutive working shifts. Based on the results, a workflow is proposed for the use of the entropy analysis in real-time industrial setting.
