The traveling grate is comprised of chain that carries the pellets like a conveyor. The difference is that the grate chain allows air to pass through it. The grate chain travels flat and strait. There are several compartments the pellets are exposed to different heat. Once the pellets are discharged into the kiln the grate chain returns underneath.

Raw coal is burned in furnaces or chain grate boilers. In this work, we studied the chamber combustion mechanism in a chain grate boiler (CGB) with a capacity of 20 t/hr. A mathematical model was built using Computational Fluid Dynamics (CFD). It was found that chamber combustion with swirl burners instead of grate firing has a positive effect on NO emissions.
