CFB boiler wear resistant castable

Classification:

Product Details

The CFB boiler construction body is extremely complex, the factors of large amount of construction, high pulverized coal flow rate and large flow that demand the lining refractory with high strength, good wear-resistance, and excellent workability. Wear resistant castable refractory provided by us is of high density, high strength, high resistance to wear and erosion, volume stability. It is widely used in erosive-wear parts of the circulating fluidized bed boiler.

Wear resistant castable refractory features:

1. High strength and high stability

2. Small thermal conductivity

3. Strong wear resistance and erosion resistance which can improve the boiler's running time

4. Convenient construction to improve working efficiency
