In most industries, maintaining a high profit level is synonymous with maintaining equipment efficiency and long-term reliability. This is particularly true for industries using rotary kilns in their processes, such as production of cement, lime, bauxite, fertilizer, or DRI. Any shutdown induces high costs. To increase production rates, reduce operating costs, improve the burning process, and save energy, it pays to select a kiln monitoring system wisely.
Monitoring the evolution of hot spots is the primary role that thermal scanning plays to detect any risk of permanent damage to rotary kilns. Electro Optical Industries, formerly HGH Infrared Systems, provides leading-edge kiln scanners, with the highest resolution and sensitivity. They can give early warnings of a single refractory brick fall.
Kiln scanners, which continuously monitor kiln shell temperature, have proven to play a key role in the economic performance of the cement production process.
Even though rotary kilns have been used for decades, monitoring its burner remains a challenge, even more so at a time when energy sustainability is so important. Because of standard fuel restrictions, the use of alternative fuels is constantly increasing, thus making control of the flame pattern, size and temperature crucial.
