Thank you very much.  Can you tell us the possible ways to break this coatings without kiln shutdown

if it is affecting on your production means due to to blockage, so use the man power at the approachable points, if it is not helping then you must take a small stoppage  

Hi:

Does liquid phase refer to (excessive) melting of low T components/intermediates? If yes, is it more reasonable to control the T-profile along the (critical) kiln zones? Having said that, how do you that? Does anyone have experience with thermo-couples in the lining?

Rgds,

Put air blasters at appropriate locations with sequential timers and use them regularly.
