Coal Analyzer

The new Coal Quality Manager (CQM), an on-line coal analyzer, is designed to provide quality management for coal processing facilities, loadouts, terminals, and docks. It provides a full elemental analysis for coal for quality control. Every minute, information is provided on sulfur, ash, moisture, heating value, lb. SO₂/Mbtu, ash constituents and ash fusion. This data can be used by a mine or prep plant for loadout or contract monitoring, to blend varying grades of coal, to sort coal by quality, or to provide data on sulfur and SO₂. By precisely sorting or blending, coal operators can realize economic advantages while producing a consistent product.

The analyzer's modular design includes an input hopper, conveyor and flow control system. Additionally, a new spectrometer design allows minimal neutron source for high performance to provide low life cycle costs. Advanced Digital Signal Processing (DSP) electronics are integrated with a new spectral processor. And improved signal-to-noise ratio has been achieved by a new electronics package, and calibration is stable. This program can be used to analyze raw coal, clean coal, blended coal or refuse, no matter its type or rank. It also uses Prompt Gamma Neutron Activation Analysis (PGNAA).
