  • How Circulating Fluidized Bed Boilers Work? - Bright Hub

    Feb 22, 2009 · In coal fired boilers the ash from the coal itself will be the makeup material. When firing bio fuels with very low ash content sand will be the makeup bed material. For high Sulphur coals Limestone addition to the bed material reduces SO2 emissions. CFBC uses crushed coal of 3 to 6 mm size. This requires only a crusher not a pulverizer.Learn More
