What factors should be considered in the selection of lining materials for circulating fluidized bed boiler (CFB boiler)?

August 03, 2018

The performance of CFB lining materials should have the following requirements:

1. The inner circulation vortex type turbulent bed lining requires high wear resistance, high temperature resistance and erosion resistance;

2. The lining of the inlet section of the high temperature external circulation separator requires high wear resistance and high temperature resistance;

3. The inlet of the medium temperature external circulation separator requires high wear resistance and high temperature resistance;

4. Medium and high temperature external circulation separator cylinders require heat resistance, heat insulation and low thermal inertia;

5. Ignition combustor flue requires high heat resistance;

6. The suspension chamber requires high heat resistance, wear resistance and low thermal inertia.
