Process Burners 101 - aiche.org

burners located in Low-NOx burners delay combustion by staging the air or fuel in multiple zones. In this way, the initial fuel-air mixture is deliberately made very rich or very lean, which slows the combustion process and reduces the peak flame temperatures Tile Staged Fuel Gas Tip Mounting Plate Damper Primary Fuel Gas Tip Plenum p Figure 3.

Cement kiln - Wikipedia

The logical development was to install a specially designed combustion chamber at the base of the preheater, into which pulverized coal is injected. This is referred to as an "air-through" precalciner, because the combustion air for both the kiln fuel and the calciner fuel all passes through the kiln.
