Abstract
Improved methods and apparatus for accumulating and conveying hot ash produced by an incinerator are provided. The method is comprised of the steps of continuously conducting hot ash from the incinerator to a closed oscillating housing which includes first and second compartments. The compartments are connected by an internal door for sealingly isolating the first compartment from the second compartment, and the second compartment has an ash discharge door connected thereto for sealingly isolating both the first and second compartments when the internal door therebetween is open. The oscillating housing is continuously operated in cycles whereby the ash conducted to the first compartment is accumulated therein and conveyed over the floor thereof to the second compartment, and the ash received in the second compartment is conveyed over the floor thereof and discharged therefrom without air infiltration from the housing to the incinerator taking place.
