Rotary ash cooler is used to cool down bottom ash of CFB boiler in power plant. Temperature of hot ash above 1000℃ is reduced to 80~100℃ in a short time by cooling water. Bottom ash could be used as building material after processing. A rotary ash cooler consists of feeding & discharging unit, drum body, driving system, cooling water system, control system, etc.
Cooling water consumption (W, m3) for one ton of ash could be calculated by this:
W=0.24 * (T1-T2) ÷ (Te-Tt)
T1-T2: temperature difference between input and output ash.
Te-Tt: temperature difference between input and output water.
