    摘要: An enclosed drainage facility to dry municipal waste combustion ash has a plurality of spaced elongated channels to drain by gravity, water from piles of ash into a disposal or reclamation pool. The channels are sloping concrete ditches leading to a common trough or pipe to a covered storage basin. Steel plates pierced with a plurality of spaced slender slits abut each other to cover each channel. The atmosphere in the facility is changed by being pumped into one side of the facility and exhausted adjacent an opposite side. Also, a process for drying municipal waste combustion ash includes dewatering and drying of ash piles in an atmosphere of warm dry air for a period of time necessary to reduce the moisture to about 28%.
