Abstract
A furnace having a thrust grate formed of grate bars which are loosely disposed on alternate movable and stationary grate bar supports, having freedom of movement to tilt in a vertical direction. In a horizontal direction, a grate bar is fixed on each grate bar support, preferably in the middle, and neighboring grate bars are connected to each other, the outermost grate bar on the stationary grate bar support being coupled to a driving element and which, upon thermal expansion, displaces a side shield with respect to the furnace wall.
