Presentation of HASLE Refractories A/S Ceramic Diptube Case Story Ceramic Diptube in the Lowest Stage Cycloneat a plant in Thailand www.hasle-refractories.com hasle@hasle-refractories.com
Country: Thailand Plant group name: - Plant name: XX- Kiln no.3 Main equipment supplier: Polysius Production capacity: 8,500 TPD Number of production lines: 3 Run factor: 0.90 Main fuel: Coal, Fuel Oil and RDF Fuel (Fuel from burning garbage)
At the beginning, we installed Ceramic Diptube (CVF) at Both of the Lowest Stage Cyclone. However we found it was fallen down after 6 months. We inspected but we could not find any possible root cause because they were still running the Kiln so we could not went inside Cyclone for checking.
After they shutdown, we went inside cyclone and found some damage Castable in the Cyclone Roof. We summarized and concluded the Roof Castable was fallen down first. After that the hot gas burnt the Steel Ring and Ceramic Diptubes were fallen down by the stress from the Steel Ring.
Due to the quality of Castable (Other Supplier) which used in the Cyclone Roof could not give the enough lifetime. It was fallen down after 6-12 months. We recommend them use high quality Castable in the Cyclone Roof because it is the important area where take effect with the Ceramic Diptube. Finally they have changed to HASLE D39A. We reinstalled Ceramic Diptube again in Jan, 2009. Now lifetime is more than 33 months and it is still hanging.
HASLE Ceramic Diptube after 29 months service life. Now lifetime is more than 33 months and it is still hanging.
