REFRACTORY BED MATERIAL.

Composition with refractory silica sand and other minerals.

Generally used in FBC & CFBC boilers. Also called as boiler sand or bed materials.

Our 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.

Special Characteristics:

• 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

REFRACTORY BED MATERIAL for CFBC Boilers

Our 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
