Jun 23, 2015· Power Plants Shifting to Dry Bottom Ash Handling. June 23, 2015. ... One study found that total operation cost of a dry system versus a wet one reduced costs by more than 50 percent. These benefits are why newer plants are considering adopting dry bottom ash handling. For example, there''s a story about a new 800 MW coalfired plant, ...
power plant, less coal needs to be fired. This reduces the burden on the coal handling system, conveyers and crushers. Also, since dryer coal is easier to convey, this reduces maintenance costs and increases availability of the coal handling system. Crushed coal is fed into the bunkers from where it flows by gravity to the coal feeders.
