High-Temperature Boiler Camera Systems


Application Highlights
Portable and fixed Lenox FireSight Boiler Camera Systems enable power generation plants to increase boiler efficiency and reduce shut downs and maintenance costs. By viewing directly inside a boiler you can:

   • Monitor the fire line position and complete burn cycle.
   • Prevent overheat situations near tube walls or refractory
   • Optimize fuel/air ratios by viewing burner performance
   • Monitor the conveyance of materials on the grate
   • View into the ash hopper to look for bridging

Typical locations for installing fixed Lenox FireSight® Boiler Cameras in a stoker fired boiler:

  1. One FireSight Camera System – (Direct 60° or 90° FOV) installed through an available port (above the burners) in the nose arch section of boiler. - or -
  2. One FireSight Camera System – (Direct 90° FOV) installed through door viewing upstream the grate. - or -
  3. One FireSight Camera System – (Right Angle 55° FOV) installed through an available port or door located above burners.
  4. An additional FireSight Camera System – (Direct 60° or 90° FOV) can be installed through the door to view down into the ash hopper to look for bridging.

with extreme durability, higher resolution, a time-tested cooling system, a longer warranty, and a much lower
average cost to operate.

Fixed and portable Lenox FireSight Boiler Camera Systems aredesigned for applications up to 3000°F (1649ºC) and require a boiler wall penetration of only 2-3/8 in. (61mm). With its small size, the system will normally fit between boiler tubes and can often be used with existing wall penetrations. Lenox FireSight Systems consist of a high- resolution (540 line), color CCD camera and sophisticated light volume control, a Lenox exclusive that allows an operator to remotely adjust the amount of light transmitted to the camera eliminating the flaring / blooming common with other systems. Quartz optics, another Lenox exclusive, are used and can withstand temperatures up to 1200°F (649°C) higher than the glass lens used in other systems. The compressed air-cooling system provides reliable performance while using considerably less air than competing systems. The fixed system Wall Box mounting assembly provides a protective housing forthe system and serves as the primary coolant shroud.

Optional fixed system accessories include an Automatic Retract System that automatically pulls the Lenox boiler camera back should a loss of cooling occur, preventing possible over -temperature damage to the furnace lens assembly; a high efficiency compressed Air Filter System for removing oil, water and particulates providing clean air to the FireSight system insuring trouble- free performance and a clear view of the combustion. It uses a self–purging coalescing filter and a pressure differential switch, which may be wired to an alarm, letting the operator know when its time to change the filter elements. Flat CRT or Flat LCD monitors and a Digital Video Recorder are also available.
