ABSTRACT:
The grate of an industrial furnace is assembled of elongated grate bars which form rows of neighboring grate bars and the grate bars of neighboring rows partially overlap each other. Each grate bar has a top wall, a front end wall and two sidewalls, and such walls define an air-admitting passage having a portion in one or more hollow upward extensions of the top wall close to the front end wall. The extensions have transverse openings which discharge air from the respective portions of the passages into the surrounding atmosphere, namely into fuel which is deposited on the grate. The openings of each extension are located in planes which are inclined to the longitudinal direction of the corresponding top walls through angles of 80-90 degrees, and such openings can be inclined forwardly, rearwardly, downwardly or upwardly. If the grate bars have top walls with several extensions, the openings in the extensions of each grate bar can be staggered relative to each other. This also applies for the openings in the extension of neighboring grate bars. The neighboring grate bars are coupled to each other against sliding movement relative to one another.
