The MAP ® dry bottom ash handling system allows for a significant increase in boiler efficiency. Ash cooling begins right after the post-combustion zone, using added ambient air. As a result, cooling and post-combustion airflows enter the boiler throat at quite a high temperature, recovering a significant amount of energy in the form of ash sensible heat, …
