GS-IRAT2000 kiln combustion temperature field infrared monitoring system is an equipment for monitoring the two-dimensional temperature field of kiln combustion. The system can not only realize the color video monitoring of combustion conditions in the kiln, but also synchronously detect the temperature of any area of interest in the field of view. It provides intuitive and reliable monitoring methods for industrial kilns to optimize combustion, save energy and reduce emissions, and improve combustion efficiency.
