An on-line low frequency microwave moisture measurement technique has been developed that is suited to both conventional coal applications and those that were previously too difficult. The wider range of application has been enabled through increased performance in dynamic range and accuracy. The performance enhancements have been achieved by utilizing recent advances in microwave technology in the 0.9-1.8 GHz frequency band intended for mobile communications applications. A commercial prototype low frequency moisture analyzer has been under development for the past two years. The main criteria in the design of the analyzer were: reduced hardware cost, increased accuracy and dynamic range of measurement, and an interactive user interface to simplify analyzer calibration and use. The first two commercial prototype analyzers were installed on the ship-loading conveyors at Dalrymple Bay Coal Terminal (Queensland, Australia) in early 2001 and monitor approximately 40 MT of shipped coal per year on conveyors carrying up to 10,000 tonne per hour. The performance and on-line calibration of these analyzers are described. |
