US 9,157,632 B2 · Water-cooled sliding combustion grate having a parallel drive

Abstract

The invention relates to a water-cooled sliding combustion grate, comprising a combination of movable grate plates (6) and stationary grate plates (5). The length of the grate plates (5, 6) passing over the grate track width is more than 6 meters. The movable grate plates (6) are driven by one parallel drive each, which comprises two separate drive units, which can each move a respective end area of a movable grate plate (6) back and forth, wherein the two drive units can be synchronized. To separate the primary air transversely over the grate track over a plurality of areas, at least one partition can extend along the grate track under the grate. Each partition is moved along with the lower faces of the grate plates (5, 6) at the upper edge of said partitions so that said partitions are fully connected everywhere to the lower faces of the grate plates.

Dependent claims

A water-cooled sliding combustion grate comprising:

multiple movable grate plates (6) and stationary grate plates (5), wherein the grate plates (5,6) lie on top of each other in a step-like manner, and the grate plates (5,6) extend continuously across the width of a grate track and have a length of more than 6 meters;
two individual drive units for every movable grate plate (6) connected to lateral ends of the movable grate plate (6) forming a parallel drive for each movable grate plate (6), each movable grate plate (6) being driven individually on lateral ends thereof by the two drive units, wherein the two drive units are synchronized with each other;
and
one or more steel girders (45) disposed underneath the grate plates (5,6) in the longitudinal direction of the grate track wherein the grate plates (5,6) are supported upon the one or more steel girders (45), and the load of incinerator charge and the weight of the grate plates (5,6) are borne by the one or more steel girders (45), and the movable grate plates (6) equipped with steel rolls on the underside thereof roll on an upper side of the one or more steel girders (45).

1 more element

A water-cooled sliding combustion grate composed exclusively of movable grate plates (6) or of movable grate plates (6) which are combined with stationary grate plates (5), in which these grate plates (5,6) lie on top of each other in a step-like manner characterised by a measurement of more than 6 meters for the length of the grate plates (5,6) extending continuously across the width of a grate track, wherein the grate plates (5,6) are supported upon one or more steel girders (45), the movable grate plates (6) are driven by a parallel drive made of two separate drive units, each end of a movable grate plate (6) can be moved forwards and backwards by means of such a drive unit, in which the two drive units can be synchronized;

wherein at least one partition (46) extends along the grate track under the grate, the stationary grate plates (5) and the movable grate plates (6) for separation of primary air across multiple sections transversely across the grate track, the partition (46) is guided with an upper edge thereof to the underside of the grate plates (5,6) so that the partition (46) is completely attached to the underside of the grate plates (5,6), the partition (46) has a recess (47) behind the movable grate plate (6) so that the movable grate plate (6) can be moved in the recess (47), whereby a separator plate (48) is installed on the backside of the movable grate plate (6), and the separator plate (48) covers the recess (47) from one side and overlaps the partition (46).
