Lenox remote viewing systems allow operators to view flame in petrochemical heaters in real time

Lenox Instrument Company's FireSight High-Temperature Remote Viewing System continuously and safely permits viewing of the flame quality and impingement if present on the tube walls of petrochemical process heaters. The FireSight System allows an operator to view the flame in real time in order to tune the furnace to eliminate this hazardous and potentially catastrophic condition. FireSight also provides an economical means to speed light off and reduce NOx emissions by permitting color video monitoring of combustion and process control in boilers, furnaces, kilns and incinerators.

Capable of operating trouble-free in temperatures up to 3,000 F (air-cooled model) or 4,250 F (water-cooled), the FireSight system is ideal for use in power plants, refineries, petrochemical and chemical plants, steel mills, paper mills, glass plants, cement kilns, and incinerators. FireSight systems are used to speed light-off, evaluate flame quality, determine status of igniters, and view flame impingement, NOx emissions and smoke. Firesight economically contributes to overall plant safety and efficiency at an excellent value. In power generation applications, for example, using FireSight systems typically reduces fuel consumption by as much as 2% and pollution by as much as 20 to 30%.

FireSight systems provide the highest image clarity in the industry. The Light Volume Control feature, a Lenox exclusive, allows the operator to easily adjust the amount of light transmitted to the camera, ensuring a high-quality image from initial light-off to maximum load. The system also features quartz optics that can withstand temperatures up to 1,200 F higher than the glass lenses used in other systems.

The furnace lens is an air-cooled periscope, ranging from 12 inches to 12 feet in length.  (The lens relies on a minimal amount of plant air for cooling.)  Furnace lenses can be supplied with a wide variety of directions and fields of view to match the specific application requirements.

The FireSight viewing system requires a boiler wall penetration of only 2-3/8 inches. With its small size, the system will normally fit in existing openings in boiler tubes and wall penetrations. The system's wall box supplies a protective housing and mounting for the camera and serves as the primary coolant shroud. The FireSight's compact CCD camera is an industrial surveillance camera designed for reliability and long life. The monitor is normally mounted in the control room providing the operator with a continuous, real-time image of the combustion chamber.
