REFRACTORY BED MATERIAL for FBC & CFBC Boilers
JAINCO’s Refractory Bed Material of Low Ferric High Temperature
product, is processed from selected super heat
duty refractory aggregates of moderate alumina
contents and of highly dense texture. This very
special Bed Material of Refractory Aggregates
fired at a temperature of 1400 Centigrade has
many special characteristics that make it a
perfect material for obtaining smooth and
perfect fluidization in Fluidized Bed Combustion
boilers with high economy of operations.
• Fully Screened Material with Accurately
Controlled Particle Size Distribution
• Free From Dust/ Fine & Over Sized Particles
• Highly Resistant Material Against Clinker
Formation
• Perfect Product For Obtaining Smooth Fluidized
Action
• Exceptional Chemical Purity with Low
Alkali and Low Iron Contents
• High I.D.T. (Initial Deformation Temperature)
• No Free Iron Particles - Passed Through Iron Separators
• Perfectly Controlled Particle Density and Bulk
Density
