When monitoring rotary kilns, one or more linescanners (one of the more popular scanning systems available) often work in parallel to gather data along a kiln’s axis. As the kiln rotates, a new line of data is generated, allowing for the entire surface of the kiln to be mapped. The data is then transferred to application-specific software

Dec 11, 2017 A second example will introduce the injection of oxygen into a cement kiln to reduce CO slip from the combustion process. A key success factor in this application is the rapid and effective mixing of a relatively small oxygen flow into a much larger flue gas stream. Lastly, oxygen was injected into an aluminum re-melting furnace to reduce large
