What should I check on the Slaker on my shift rounds?

Some things to look for are:

  • Verify that the slaker temperature sensor is reading correctly. (We suggest you measure slurry temperature with a hand held Infrared (IR) Temperature Thermometer.
  • Look for product leaks from gaskets or rubber connections connecting different parts of the feed system.
  • Ensure correct flow through water lines to the slaker seals, wet scrubber and vibrating grit screen.
  • Look for quicklime buildup in/around quicklime inlet.
  • Slaked lime buildup at outlet or inside the vibrating grit screen.
  • Sufficient exhaust suction from the wet scrubber.
  • Check the HMI/DCS alarm history.
