Pneumatic Ash Removal: Replacing Transport Water With a ...

One option for bottom ash management is a pneumatic ash removal system. This solution replaces wet bottom ash hoppers and a wet transport system traditionally used at coal-fired power plants with a dry alternative. Pneumatic bottom ash solutions were introduced in the 1920s and were widely used through the 1950s on smaller boilers.
