NIR-Borescope Glass - Melt Tank Thermal Imaging System

AMETEK Land Fixed Thermal Imagers & Line Scanners - NIR-B Glass
A borescope thermal imaging camera, specifically developed to return precise temperature measurements in glass furnace applications.  
  • Overview +

    An application-specific version of AMETEK Land’s cutting-edge NIR-B thermal imaging camera, Near Infrared Borescope (NIR-B) Glass creates detailed, live radiometric images that accurately measure temperatures inside of a glass melt furnace.

    A significant improvement over traditional manual methods of furnace monitoring, NIR-B continuously measures temperatures across a high-resolution 324,000-pixel image -  giving real-time monitoring that ensures high product quality, helps detect furnace structural damage, and improves melt tank efficiency.

    Using our proven, short-wavelength NIR thermal imaging technology, the camera connects to a Windows PC running dedicated IMAGEPro processing software. This provides accurate data analysis, along with automated alarms and control for 24/7 monitoring.

    Optimised for measuring high temperatures between 1000 – 1800 °C (1832 – 3272 °F), NIR-B Glass is suitable for glass industry applications, including: float glass, container glass, borosilicate glass and fibre glass melt furnaces.

    Shooting an optical profile may take several hours to complete, are not continuous and unreliable due to user error, while visual cameras cannot provide temperature readings. By continuously monitoring optical profiles and any point within the image, NIR-B Glass enables furnace optimization and alarms to be set to detect air and glass leaks that affect the efficiency of the furnace. 

    Continuous, high-resolution measurement ensures real-time batch monitoring, flame optimisation and the data required to improve energy efficiency and maximise pull rates without degrading the refractory lifetime. Areas of Interest (AOI) can be user defined, while a digital input function enables measurement of port arch temperatures at the moment of reversal.

    Traditional thermal imagers require large openings in the refractory wall to enable viewing of the critical area. NIR-B Glass just needs a small diameter hole to accommodate the 90° field-of-view wide angle lens tip, minimising process disruption.

    SVA LogoDesigned to auto-retract and protect the thermal imager from damage by overheating in the event of loss of water flow, air pressure, electricity supply or high borescope tip temperature alarm. The system has an air reservoir (accumulator) to ensure full retraction in the event of loss

    The NIR-B Glass is AMETEK Land’s enhanced thermal imager for glass furnace applications.

    Adding thermal-imaging capabilities that enable operators to maintain an accurate visual of the entire glass-melt tank, as well as take temperature measurements at any point in the process and in any location within the tank, is invaluable. Find out more in the latest IEEE Engineering Brief ‘Thermal Imaging Enhances Today’s Complex Glass-melt Process’, sponsored by AMETEK Land, and understand how the NIR Borescope (NIR-b) delivers a new approach.  Read More >

    Application Note - Glass Tank Refractory MonitoringGLASS TANK REFRACTORY MONITORING
    The condition of glass furnace  Refractories is vitally important to safety and process efficiency, especially towards the end of the life of the tank. Deterioration of the refractories can increase fuel Costs, and may cause glass break-outs or refractory failure. Read More > Watch the video >

    Frequent, accurate measurements of the temperature profile are necessary to reduce stresses in the glass and to optimise the cooling rate over the entire process length. Read More >
