    摘要: A bar for a rotary grate is of T-section and has an enlarged head and a fin projecting inwardly therefrom. The head is formed with an end face directed outward from the fin and a pair of substantially parallel side faces extending inward obliquely from the end face. The side faces extend at an angle of between 40.degree. and 75.degree., preferably about 60.degree., to the end face. Thus air exiting from inside the roller-grate drum flows obliquely to a radius from the drum-rotation axis. This ensures that even if the material being burned does not form a continuous layer on the surface of the roller, the air will be likely to impinge this material. The fin extends generally centrally from the head and has a centerline that generally bisects the head. The bar has ends formed with blocks projecting to opposite sides of the bar so that blocks of adjacent bars can interfit. Furthermore the bars are arranged in sets with the bars of each set aligned longitudinally with the bars of the same set and each bar is formed with at least one axially throughgoing hole. In this case the drum is provided with respective holding bars traversing the holes of each set of bars.

    摘要翻译: 用于旋转格栅的条具有T形截面并且具有从其向内突出的扩大头部和翅片。 头部形成有从翅片向外指向的端面和从端面向内倾斜向内延伸的一对基本上平行的侧面。 侧面以40°至75°,优选约60°的角度延伸至端面。 因此,从滚筒格栅鼓内部排出的空气从滚筒旋转轴线的半径倾斜地流动。 这确保即使被燃烧的材料在辊的表面上不形成连续的层,空气也可能撞击该材料。 翅片通常从头部中心延伸并且具有大致平分头部的中心线。 杆具有形成有突出到杆的相对侧的块的端部,使得相邻块的块可以互相配合。 此外,杆被设置成一组,其中每个组的杆与同一组的杆纵向对准,并且每个杆形成有至少一个轴向通孔。 在这种情况下,滚筒设有穿过每组杆的孔的相应的保持杆。
