WATER-COOLED SLIDING COMBUSTION GRATE HAVING A PARALLEL DRIVE
Document Type and Number:
WIPO Patent Application WO/2012/012909
Kind Code:
A3
Abstract:
The invention relates to a water-cooled sliding combustion grate which consists of either movable grate plates (6) or a combination of movable grate plates (6) and stationary grate plates (5). Said grate plates (5, 6) lie on top of each other in a step-like manner, and the movable grate plates (6) can be moved back and forth perpendicularly to their longitudinal direction. The length of the grate plates (5, 6) passing over the grate track width is more than 6 meters and they are supported on intermediate steel girders (45). 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. In order 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 and its stationary grate plates (5) and movable grate plates (6).
