  1. CQMCoal Quality Manager

  2. CQM • Sample-fed analyzer with a capacity of 0 to 30-tph or 20 to 70-tph • Replaces the 1812C chute analyzer • Design of the analysis zone was optimized for coal • Half the source strength of the 1812C with the same or better performance. • Material flow control designed into the unit • Smaller foot print • Moisture gauge is built into the unit • The CQM is a stand-alone unit

  19. CQM Electrical Specifications

  20. CQM and Sampling System Require Interfacing • Required signals from Sampler to CQM • Exit chute plugged (24 VDC dry contact) • Exit belt stopped (24 VDC dry contact) • Required signals from CQM to Sampling System • Analyzer Ready Signal (5-30VDC or 110VAC dry contact) • Input Hopper Overflow (5-30VDC or 110VAC dry contact) • CQM Motor on (5-30VDC or 110VAC dry contact) • All field connections are laid out on page 9 and 10 of the CQM site prep document.

  21. CQM – Flow Control • The flow control through the CQM is controlled by our PLC • Coal enters our hopper from a sampling system • The coal level is read by a Ramsey level sensor • When the coal goes above the set point, the CQM belt will turn on, and control the level accordingly

  22. Analyzer Location Issues • CQM • Since it requires a sample stream, it’s preferred to integrate it with an existing sampling system • Has to be somewhere where the topsize does not exceed 3 inches • Requires about 8-10 feet of vertical clearance • Need to allow for • electronics doors opening • source cask placement nearby • Liner removal • Level sensor at top of input hopper • Optimal flow is 3 tph to 15 tph • Would like sample increments no less often than every 2 minutes • Ideally want it as close as possible to the process being controlled
