REFRACTORY BED MATERIAL for CFBC Boilers
Refractory Bed Material
for CFBC Boilers
"JAINCO'S" refractory bed material is made out
of specially processed high heat duty refractory
aggregates of required density. Our bed material
has many special characteristics, which make it
a perfect material for C.F.B.C. and F.B.C.
boilers for obtaining perfect fluidized action.
The material is passed through high power
magnetic separators to eliminated free iron
particles. The material is processed as per BHEL
standard; however, the particle size
distribution can be given as per specific
application.
Special Characteristics:
• Accurate Particle Size Distribution
• Exceptional Chemical Purity
• Fully Screened Material through Classifiers
• High I.D.T. (Initial Deformation Temperature)
• No Formation Clinker
• Low Alkalies
• No Dust Particles
• No Free Iron Particles
• Perfect Density
