AFBC Boiler Bed Material

The Refractory boiler Bed Material is manufactured from Fresh refractory fire clay and not from pre-used fire bricks. Hence it is virgin, pure and fresh from the factory. It does not carry the impurities like the conventional bed material. The Raw material Pure Fire Clay Refractory Material has been directly source from Neyveli Lignite Corporation Limited (NLC) is a “Navratna” Government of India Enterprise, hence the superior quality Bed material with excellent features and characteristics resulting in higher efficiency and cost savings. Salient features Sri Renga Refractory Bed Material has many special characteristics that make it a perfect material for obtaining smooth and perfect fluidization in FBC & CFBC Boilers with high economy of operations. 1. Material free from fine particles 1. Precise particle size distribution 2. Excellent material for obtaining fluidized action 3. Excellent chemical purity 4. High initial deformation temperature 5. Optimal coal consumption 6. Iron free bed material 7. Perfectly controlled density 8. Low Alkali contents 9. Low down time & maintenance cost Fire Clay Bed Material Specifications Product Fire clay Boiler Bed Material Quality First Quality Material 1) Chemical Analysis Silica (sio2) – 55% Alumina (Al2O3) – 35% Iron (Feo) – Nil 2) Physical Properties Fusion Temperature 1300 - 1400ºC Bulk density(gms/cc) 1050 - 1100Kg/m3 3) Sieve Maximum Particle Size 2.36mm Minimum Particle Size 0.85mm Advantages of the boiler bed material 1. It’s manufactured from fresh refractory clay and not from pre-used fire bricks. Hence it is virgin, pure and fresh from the factory. It does not carry the impurities like the conventional bed material. 2. The content of iron is very negligible. Except for the basic content in the clay the material is not attracted to any foreign iron contamination. 3. Corrosion to the boiler bed coil tubes is prevented by using this product. 4. It is free from moisture. In general conventional bed material
