Control of cement clinker production in a wet process rotary kiln by analysis of sulfur in the end product

摘要

An apparatus for producing cement clinker using a high sulfur fuel includes a wet rotary kiln, at least one sulfur analyzer, a controller, and a burner. The wet rotary kiln has a first end and a second end and processes a slurry of a raw material mixed with a certain quantity of coarse grinded high sulfur fuel received at the first end to produce cement clinker. The sulfur analyzer is produces a measure of the sulfur content of the cement clinker. The controller receives the measure from the sulfur analyzer and controls a concentration of oxygen in the kiln based on the measured sulfur content in the clinker end product. The burner is installed in the kiln at the second end and operates to burn a high sulfur fuel.
