Fuel Mill Figure For Portland Cement

In cement manufacturing, conditions favorable for formation of NOX are reached routinely because of high process temperatures. Essentially all NOX emissions associated with cement manufacturing are generated in cement kilns. In cement kilns, NOX emissions are formed during fuel combustion by two primary mechanisms:

Portland cement is a complex product made from very simple and abundant materials: limestone and clay (or shale). Very precise proportions of these two basic materials have to be mixed with some additions to create a raw meal with a precise chemical composition; this will result in the production of clinker through the complex pyroprocessing presented in Figure 3.1.
