When burning solids in furnaces a uniformly high temperature must be maintained to achieve optimum combustion. A sufficient supply of oxygen is necessary for this. The primary air is drawn downwards through the downwards-pointing flames by the draught created by the chimney, and then carried away. The primary air supplied is usually not enough to achieve a sufficiently high temperature. The compaction of the solid fuel directly above the combustion zone is also a problem. The grate links are formed as hollow rods through which secondary air flows, emerging downwards from the grate links. In this way, it flows directly into the combustion zone and improves combustion. In addition, spacers are provided on the grate links, which prevent the fuel compacting. In this way, the access of the oxygen to the fuel and the combustion is substantially improved. Grate in furnaces, boilers and the like for solid fuels.
