Go for additional blasters and pocking holes with proper and safe approach.

Dear

             Higher % CL In hot meal need to reduced %degree of calcination by reducing temp and increase Oxygen level in calciner and reducing coating formation into bottom cycline feed pipe and cone.

Need action for above condition by reducing feed  with coal / af feed rate and cleaned feed pipe cone timely before draft got zero .

You may install gama ray at bottom cyclone for avoid plant stoppage.

With regards

gks
