Boiler Crushed Refractory Bed Material is commonly used in fluidized bed combustion (FBC) boilers, such as Circulating Fluidized Bed Combustion (CFBC) boilers and Atmospheric Fluidized Bed Combustion (AFBC) boilers. It plays a crucial role in heat transfer, combustion efficiency, and reducing emissions.
Key Features of Crushed Refractory Bed Material
High Refractoriness – Withstands high temperatures (typically 1200-1400°C).
Low Reactivity with Fuel & Ash – Prevents unwanted chemical reactions.
High Strength & Hardness – Resists attrition and maintains bed stability.
Thermal Shock Resistance – Handles rapid temperature fluctuations.
Optimum Particle Size – Ensures smooth fluidization and efficient combustion.
Low Alkali & Iron Content – Reduces slagging and fouling in the boiler.
Applications
✅ AFBC & CFBC Boilers – Used as a bed material for efficient combustion. ✅ Biomass & Coal-fired Boilers – Helps in uniform heat distribution. ✅ Waste-to-Energy Plants – Supports incineration of waste materials.
Common Materials Used
�� Alumino-silicate Minerals (High alumina content for thermal stability). �� Crushed Fire Clay Bricks (Processed to specific grain sizes). �� Silica Sand (in some cases) (Lower cost but less durable).
Refractory bed material is a crucial component in fluidized bed combustion (FBC) boilers, circulating fluidized bed combustion (CFBC) boilers, and other high-temperature boiler systems. It is used to ensure efficient combustion, maintain heat stability, and prolong the life of boiler components.
Key Properties of Refractory Bed Material
High Refractoriness – Can withstand high temperatures (up to 1400°C or more).
Thermal Stability – Resists thermal shock and maintains performance under fluctuating temperatures.
Chemical Resistance – Resists slagging, fouling, and chemical reactions with fuel or ash.
Uniform Particle Size – Ensures smooth fluidization and efficient combustion.
Low Iron and Alkali Content – Prevents unwanted chemical reactions that can degrade the refractory.
Types of Refractory Bed Material
Alumina-Based Refractory Sand – Commonly used in FBC and CFBC boilers, containing a high percentage of alumina and silica.
Silica Sand – Used in less demanding applications, but can degrade faster in extreme conditions.
Specialized High-Performance Refractories – Designed for specific industrial applications with customized compositions.

Acid-proof cement mortars are specialized construction materials designed to withstand acidic environments. These mortars are used in industries where structures are exposed to aggressive chemicals, such as chemical plants, battery rooms, pickling tanks, and food processing units.
Types of Acid-Proof Cement Mortars
Silicate-Based Mortars
Made from sodium or potassium silicate as a binder.
Resistant to strong acids but not effective against hydrofluoric acid or alkalis.
Commonly used in chemical-resistant brick linings.
Furan Resin Mortars
Contain furan resins that provide excellent acid and solvent resistance.
Used in chemical processing and food industries.
Highly resistant to organic acids.
Phenolic Resin Mortars
Provide resistance to high temperatures and various acids.
Used in power plants and industrial furnaces.
Sulfur-Based Mortars
Made from molten sulfur mixed with inert fillers.
Resistant to many acids but limited in high-temperature applications.
Epoxy-Based Mortars
Offer strong bonding and resistance to acids and alkalis.
Used for industrial flooring and tank linings.
Polyester Resin Mortars
Provide good resistance to organic acids.
Used in wastewater treatment plants.
Properties of Acid-Proof Cement Mortars
High Chemical Resistance – Protects against acids, solvents, and chemicals.
Durability – Ensures long service life in harsh environments.
Low Water Absorption – Prevents chemical penetration and structural damage.
Thermal Resistance – Can withstand varying temperatures based on the type of mortar used.
Good Adhesion – Bonds well with concrete, brick, and steel surfaces.
