Abstract
A guide system for a reciprocating grate system having a grate surface, alternating rows of stationary and movable grate blocks, a movable carriage, a fixed undergrate structure, and a driving force device. The guide system includes guide units which guide the movable carriage and the movable rows of grate blocks with respect to the fixed undergrate structure and the stationary rows of grate blocks during reciprocating stroke cycles of the driving force device. Each guide unit includes a fixed guide member and a movable guide member. The fixed guide member is attached to the fixed undergrate structure and has an upper non-linear contour with wear plates, each having a wear surface. Each movable guide member is attached to the movable carriage and has a lower non-linear contour with wear plates, each having a wear surface. When the movable carriage is in an installed position, the wear surfaces are in slidable contact with each other. The wear plates on each guide member are angularly displaced from each other to maintain lateral alignment of the movable carriage and the movable grate block rows, and provide additional wear surface area to increase the useful life of the wear plates. The wear plates eliminate the need for lateral restraints, by maintaining lateral alignment of the movable carriage and the movable grate block rows. A levelling device, including levelling bolts on the fixed guide member, prevents uneven wear of the wear surfaces during operation.
