AMETEK Land will present a paper illustrating how thermal imaging allows for the improved operation of biomass-fired boilers at the virtual 2021 International Biomass Conference & Expo (March 15-17, 2021).
Derek Stuart, Global Product Manager - Power, Combustion and Environmental at AMETEK Land, will look at how agricultural by-products, such as wood pellets, straw, and olive mill wastehave the potential to fuel a green power revolution. However, their combustion as fuel poses problems that are not present in traditional coal- or gas-fired boilers. This presentation examines the challenges and operational difficulties of utilising biomass fuels. It will also discuss how understanding the conditions inside the boiler is essential for efficient and safe operation.
Derek explains how a borescope thermal imager, such as AMETEK Land's new MWIR-B-640, can provide detailed information on the conditions within the boiler. The borescope's design allows users to position the imager outside the boiler with only a small penetration through the boiler wall. Air purging and water cooling protect the delicate optics from the harsh conditions, and an automated retraction system can withdraw the probe if either protection system should fail. This innovative borescope imager can look through luminous flames to measure the temperature of the grate and boiler tubes. This allows it to observe slag build-up on the boiler tubes and view the biomass fuel as it burns on a moving grate.
"Radiometric thermal imaging is an excellent tool that has many applications in the biomass sector," Derek explains. "A long-wavelength imager can monitor the temperature of stored biomass to detect the early stages of spontaneous combustion. I'm delighted to share this latest application for a mid-infrared imager with the audience and look forward to a lively discussion afterwards."
AMETEK Land offers a full range of temperature measurement and combustion monitoring solutions for the biomass industry.
AMETEK Land's new MWIR-B-640 borescope is a fully radiometric imager. This means it can determine the temperature throughout the entire field of view. The measured data can bestored and trended over a boiler's lifetime, providing a continuous record of the conditions within the boiler.
This innovative new borescope features advanced spectral filtering as well as a high thermal and spatial resolution to deliver clear live images of the boiler and fuel. It features more than 300,000 accurate point temperatures measuring in the ranges of 300-1200 °C (572-2192 °F) and 500-1800 °C (932-3272 °F).
The high-resolution image of the MWIR-B-640, combined with a 90° wide-angle field of view, allows multiple areas within the image to be measured simultaneously. With the wide-angle view into the boiler, image data can be viewed in real-time from the safety of the control room. With only a small opening in the wall, the MWIR-B-640 can accurately profile the temperature of the entire boiler without affecting the internal atmosphere or energy consumption.
