Rotary Ash Cooler for CFB Boilers

The Rotary ash cooler is invented by Chinese (created in China). SONGLING has a number of patented technologies in design of rotary ash cooler. SONGLING's rotary ash cooler accounts for over 70% market share in China, ranged from 50MW to 600MW CFB unit in coal fired power plants. Several types of ash cooler with transferred technology from Europe and US, such as screw cooler and the fluidized type of ash cooler, were installed in China initially. As the frequent failures of those initial designs of ash cooler became apparent, now almost all those coolers have been replaced by rotary ash coolers.
