Batch sulfurmeter installation and testing at the Paradise Coal Preparation Plant

A prototype instrument developed by Science Applications, Inc., for online measurement of the sulfur content of coal has been installed at TVA's Paradise Coal Preparation Plant. This batch sulfurmeter analyzes coal using the principles of prompt neutron activation analysis and has the capability of returning an as-received sulfur value after a 100-second analysis time. The instrument operates in a continuous batch mode with approximately a 6-minute cycle time under normal operating conditions. This paper primarily discusses installation, startup, and early testing experience for the sulfurmeter. 12 references, 13 figures, 6 tables.
