FireSight® Air-cooled Systems
for applications to 3000°F
The FireSight viewing system requires a boiler
wall penetration of only 2-3/8 in. With its small size, the system
will normally fit between boiler tubes and can often be used with
existing wall penetrations.
FireSight systems provide the highest image clarity in the industry.
The Light Volume Control feature, a Lenox exclusive, consists of
a remote-controlled motorized iris and spot filter located in the
furnace lens. With the Light Volume Control, an operator can easily
adjust the amount of light transmitted to the camera, eliminating
the flaring common with other systems and ensuring a high-quality
image from initial light off to maximum load.
FireSight also has a proven record of reliable performance that
is unmatched by any other system available today. Lenox manufactures
all critical components, including the grinding and polishing the
lenses in the company's own optical shop. The system features quartz
optics that withstand temperatures up to 1200°F 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 rugged furnace lens/periscope assembly
has been proven reliable in hundreds of applications and, in fact,
tests show it will survive far longer than competing systems in
the event of a coolant interruption.

System Components
The wall box supplies a protective housing and mounting for the
system and serves as the primary coolant shroud. The furnace lens
is an air-cooled periscope, ranging from 12 in. to 12 ft. in length
that is rated for operation in temperatures up to 3000°F. Furnace
lenses can be supplied with a wide variety of directions and fields
of view to match the specific application requirements. An air-cooled
camera housing provides a controlled environment for the closed
circuit TV camera. By adjusting the amount of light transmitted
to the camera, the Light Volume Control insures a high-quality image.
The compact camera is an industrial surveillance camera designed
for reliability and long life. An integral compressed air system
supplies clean air for cooling and particulate removal from the
lens. The monitor is normally mounted in the control room providing
the operator with a continuous, real-time image of the combustion
chamber.
