Regional Contained Landfill – Gas Flare Blower Investigation (August 19, 2009)

  • A landfill gas flare system blower was reported as operating with excessive vibration.
  • VESCO performed a Mechanical Integrity Inspection and found numerous issues with the fan bearings, remote lubrication system, blower housing drains and the drive system.
  • VESCO replaced the blower bearings, leveled and laser aligned the blower to the blower housing, modified the remote lubrication system to mitigate observed failure mode, restored the blower housing drain system with recommendations to modify the standard operating procedure to preclude ingestion of condensed landfill gas condensate and recommended belt upgrade.
  • The landfill gas system testing and servicing company has asked VESCO to look at additional systems for vibration-related issues.
