Abstract (en)

[origin: WO9963270A1] A grate device (1) for a combustion furnace comprises a grate element (2) and a turnable shaft assembly (3) connected thereto. The grate element (2) has a first system of ducts (17.1) for circulating coolant through the grate element (2). The shaft assembly (3) has a second system of ducts (17.2), which communicates with the first system of ducts and forms a coolant inlet and outlet (14, 16). The grate element (2) comprises a girder means (6) which is non-rotatably connected with the shaft assembly (3) and which contains a part of the first system of ducts (17.1), which part communicates with the second system of ducts (17.2). The grate element (2) comprises a plate means (5) which is mounted on the girder means (6) and forms a grate area and through which the remaining part (7) of the first system of ducts extends for cooling the grate area.
