Overview:

Bed material is a specialized granular substance used in fluidized bed combustion (FBC) boilers. It plays a crucial role in the fluidization process, ensuring efficient heat transfer and combustion by providing a stable medium in which fuel particles can suspend and burn uniformly.

Types of Bed Materials:

1. Fire Bricks Bed Material
2. Ceramic Bed Material

Size:

0.85 to 1.5 mm
0.85 to 2.0 mm
0.85 to 2.36 mm

Properties:

Bed materials are typically composed of refractory-grade silica or alumina, chosen for their ability to withstand high temperatures and resist chemical reactions. The material must have the right particle size distribution, density, and hardness to ensure proper fluidization and longevity inside the combustion chamber.

Applications:

Used in fluidized bed boilers across various industries including power plants, chemical processing, and waste management. Bed materials facilitate uniform combustion, reduce emissions, and improve heat transfer by maintaining a constant and active bed of particles in the boiler.
