Abstract
A storage bin for handling and discharging plug flow material uses shrouds to prevent wedging of plug flow material such as refuse derived fuel between vertical screws and the end walls of the bin. The bin is divided into two separate sections by the vertical screws. Wedging of plug flow material in both bin sections and material discharge is then stopped. The shrouds force the plug flow material into the active surface area of vertical screws and continuous discharge through an elongated discharge aperture is assured. Two horizontal screws are used to further augment material discharge beneath the elongated discharge aperture. The two horizontal screws are parallel and the bottom of vertical screws are between the two horizontal screws.
