COAL INDUSTRY
SPECTRAFLOW CROSSBELT ANALYZER: An online NIR sensor designed to analyze coarse ROM material directly on a conveyor belt (On-belt coarse material sensor).
The Crossbelt Analyzer features a user-friendly design that allows quick, non-invasive installation above the conveyor. Its eight halogen light sources supply sufficient energy to capture absorption spectra from run-of-mine (ROM) materials with wide and highly variable particle size distributions.
SPECTRAFLOW AIRSLIDE ANALYZER: A flagship solution for analyzing finely ground material in an airslide.
The Airslide Analyzer is engineered to support higher measurement accuracy throughout the process chain and to minimize reliance on laboratory analyses for process control. It provides constituent measurements down to ppm levels in fine materials conveyed to and from mills, furnaces, and smelters.
COAL INDUSTRY APPLICATIONS
Near-infrared (NIR) technology has been applied for more than three decades in online analysis of organic materials such as fuels, food products, and pharmaceuticals. This is because organic compounds exhibit strong and distinct responses in NIR spectra, making them significantly easier to analyze than inorganic minerals with rigid crystal structures. In coal applications, both the inorganic ash content and the organic components—particularly carbon and moisture—are critical parameters. For this reason, NIR represents the most suitable analytical technique for coal and has been extensively validated through laboratory testing.
At present, PGNAA systems are used in mining operations; however, their limited measurement accuracy has prevented the successful implementation of any online solution for gasifier control in power plants. SpectraFlow is currently the only online analyzer on the market capable of determining the chemical composition of the gasifier feed in real time.
