BOILER & FURNACE COMBUSTION IMAGING
The Opportunity The continued rise of worldwide electricity consumption has put an ever increasing demand on power generation facilities. With coal fired power plants, this demand results in challenges to increase production while minimizing environmental impact.
Optimizing the performance of the downtime. In addition, lance systems coal boiler can provide immediate typically operate blindly; attempting benefits and maximize the Rankine to uniformly target all boiler tubes for cycle efficiency. One common problem cleaning. It is possible to reduce the is the buildup of fly ash and soot furnace power to obtain a visual inspec- on the boiler tube surfaces which tion of some tubes, but the efficiency reduces the heat exchange efficiency. loss during this process is significant. These deposits (Slag) can be removed Properly tuning the combustion process with lances, and similar systems, but can help reduce the buildup of tube identifying when to implement this deposits, and can minimize emissions. action can be difficult to estimate and However, switching coal composition routine periodic lance operation can can further complicate the tuning cause thermal stress to boiler tubes, process, and lead to varying fouling of leading to failure and unscheduled the boiler tubes.
Our Solution Advanced Energy leverages more than 25 years of infrared thermal imaging experience to developing the BoilerSpection™ SD solutions specifically designed to address the monitoring of heat exchange tubes in coal fired boilers and furnaces. Using a custom narrowband 3.9μm filter and precision boroscope optics, we view through boiler flames and provide the clearest image of boiler tubes available. BoilerSpection™ systems provides a unique view into the boiler, allowing operators to have more precise control of their boiler. • Real time continuous monitoring. • World class uncooled VOx thermal • Professional thermal imaging Crisp, live images of boiler tubes imager with water cooled preci- software for historical trending allowing continuous monitoring sion boroscope optics for superior and statistical analysis.
