Composition with refractory silica sand and other minerals, generally used in FBC & CFBC boilers. Also called as Boiler Sand or Bed Materials or Fire Clay Bed Materials. Parth Minerals 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.
Parth Minerals 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
- Accurately Screened Material Free From Dust and Fines
- Perfect Particle Size Distribution
- No Over Sized Particles
- Resistant Against Clinker Formation
- Perfect in Obtaining Smooth Fluidization
- Exceptional Chemical Purity
- High I.D.T (Initial Deformation Temperature)
- Very Low Alkali Contents
- No Free Iron Particles – Processed Through Magnetic Separators
- Perfectly Controlled Material Density
PERFORMANCE
Zero Wastage – Low Consumption
Fully Screened Material and Perfect Particle Size Distribution, Free from fines, dust and Over size particles eliminate wastage and reduce Consumption of material including no free flow or wastage in air during operation.
Uniform Heat
Intermediate Particle Distribution of the product in required percentage as per boiler size, height and design leads to perfect conductivity of heat in the boiler.
Resistant against Clinker Formation
The Low ferric chemical property and High Initial Deformation Temperature (PCE value) makes it highly resistant to abrasion and an ideal product against clinker formation at high temperatures.
Safest Product for Boiler Tubes
Exceptional Chemical Purity, low alkalis and moderate alumina contents of the material make it neutral in chemical nature having no chemical reaction with boiler tubes and carbon fuel. These special chemical properties increase efficiency and life span of boiler tubes as well as refractory lining.
Economy of Product
- The product is excellent in operational properties and performance.
- It is highly economical in use in comparison to materials processed from low temp.Ceramic waste.
- Parth Minerals bed material offer phenomenal saving of over 40-50% on account of perfect size, low wastage, chemical purity, high refractoriness and heat conductivity.
- The smooth operational properties and extensive particle life of the material results in low downtime.
- The material is most suitable for recycling in certain conditions on account of its very special feature of refractoriness.
