Overview

 

NDTV-1 priscop furnace flame television system is applicable to coal, oil, gas flame surveillance. The flames are directly displayed on the screen for operation observation and combustion timely adjustment. It can effectively prevent boiler furnace explosion. The flame burning in the furnace can be truly observed by which using high temperature probe and the sapphire special ceramic materials.This equipment is designed small in size, wide field of view, less consumptionof air, strong interference capability, resistance to high temperature, resistance to corrosion. And the pictures are clear.

Principle

 

NDTV-1 priscop furnace flame television system, electric propulsion will be through optical probe into the furnace, two goals images through image lens, aperture, filter, formed in the image plane of the camera away from the observation hole CCD target level, minimizing the thermal radiation into the camera, the optical signal CCD camera will be converted into a video signal, the control room via video cables to the monitor, the monitor displayed on flame Dynamic Image. Pressure switches used to detect the pressure of the cooling wind, fine thermocouple temperature probe detected when the pressure below the set value or ultra-high temperature probe, the probe will automatically exit

Product Features

 

multiple probe swirl and cooling, cold wind to breeze. The pressure in the cooling wind very low (≥ 245 Pa) circumstances can guarantee camera probe on the temperature at 50 ° C, and cold wind source can be sent or fan the flame detector wind cooling wind. Instrumentation and unnecessary use of compressed air.
 camera lens probe without coking phenomenon occurred in the forefront of the probe design Purge Wind in the establishment of the scientific premise of the mathematical model, using computer optimized design and test laboratory wind characteristics and practical application test. Purge wind that is cold wind.
 probe Overheating, when the cooling wind suppress probe can automatically withdraw from the furnace; can manually into a state of emergency, retreat.
 furnace wall installation of welded connections, perspective and access to probe the length of the furnace there will be major adjustments cushion to ensure that the center of the screen to avoid caused as a result of improper installation deviated from the image center phenomenon.
 imaging group by sapphire lens made by the special structure of the lens made of high temperature ceramics, in order to ensure camera probe in the high temperature environment, the result of the probe to avoid frequent Over-temperature furnace to withdraw from the phenomenon.
 probe microscope with aperture of the device or aperture adjustment, adjustable image shades to monitor the brightness of images suitable to facilitate observation.
 camera using anti-corrosion cover double stainless steel, laminated in which the cooling wind, are all part of Interface Design sealed structure; plug used waterproof; probe for stainless steel tube; local control box protection rating for IP65. All-weather so that the system can work.
 use of screen / switches, monitors, the two images can be achieved at the same time, also can be displayed.
 power systems, such as die Fault Alarm System
