REFRACTORY BED MATERIAL for FBC & CFBC Boilers

JAINCO’s Refractory Bed Material of Low Ferric High Temperature Super Quality is made out of high quality and super heat duty refractory aggregates of high alumina contents & dense texture. Jainco’s this very special Bed Material has many special characteristics that made it a perfect material for obtaining smooth and perfect fluidization use in Fluidized Bed Combustion Boilers (FBC) and Circulating Fluidized Bed Combustion Boilers (CFBC).

 Special Characteristics:

• Fully Screened Material Free From Fine Particles
• Fully Resistant Against Clinker Formation
• Perfect Product For Obtaining Fluidized Action
• Accurate Particle Size Distribution
• Exceptional Chemical Purity
• High I.D.T. (Initial Deformation Temperature)
• Low Alkali Low Iron Contents
• No Free Iron Particles - Passed Through Iron Separators
• Perfectly Controlled Density

The Product
Jainco’s Refractory Bed Material for FBC and CFBC boilers is a very exclusive refractory product, processed from special refractory aggregates of high chemical purity, dense consistency, high refractoriness, etc., and is apposite to sustain technical properties for fluidization at high temperatures of 1400⁰ C with different fuels, under most critical working conditions.

Research & Development
The Bed Material has been developed is a result of our own constant in-house research and development work and field experience for over 16 years; and also in accordance with the technical support / guidance from time to time extended by the leading manufacturers of FBC and CFBC Boilers like BHEL, TBW. The technical criteria and particle size distribution of the material is predetermined for practicality as well as economy of the product on the basis of technical requirement with specific fuel and boiler design.

Special Characteristics
Jainco’s Refractory Bed Material has many special attributes that makes it a transcendent material for FBC and CFBC Boilers with greater scale of economy.

• Zero wastage – Low consumption
Fully Screened Material – Perfect Size: Free from Fines & dust and over size particles separated through Air Classifiers. This subsequently eliminates wastage of material through air while in operation. Perfect Material and Particle Density gives perfect and smooth fluidizing action and enhances its Low Consumption properties.

• Uniform Heat
Accurate Intermediate Particle Size Distribution in required percentage of our product gives uniform distribution of heat/temperature in boiler bed area.

• Resistant against Clinker Formation
High I.D.T. (Initial Deformation Temperature) gives high Refractoriness, which makes it resistant to abrasion. As a result of being passed through high power Magnetic Separators, the material is Low Ferric and does not contain any free iron particles. Thus making it a perfect product against clinker formation at high temperatures.

• Safest product for boiler tubes
Highly Exceptional Chemical Purity and low alkalis makes it neutral in chemical nature that gives longer life to boiler tubes and refractory lining as it has no chemical reaction with boiler tubes and carbon fuel. Due to its smooth operational properties and long particle life it results in low down time and maintenance cost.

• Economy of Product

• It has been observed that Jainco’s Refractory Bed Material gives a saving of over 45% on its use on account of perfect size, low wastage, better quality and chemical properties, high refractoriness, high temperature properties, low operating consumption and minimal down time in comparison to other similar local products.
• The product has wide acceptance all over India and Indonesia and is being regularly used by almost all FBC and CFBC Boilers of BHEL, Thermax etc.
• The product has no match and none to second, as it is excellent in operational properties and performance.
