Cement Kilns: Firing systems

Control of the fuel feed to the kiln is inferior because of the time lag, because the feed of fuel in lump form is more crude, and because wet fuel can flow erratically. Much more cool primary air is needed to convey the fuel through the system, restricting flame temperature.
