Preliminary Study on Application of Infrared Thermal Imaging Technology in Combustion Control of Coal-fired Boilers

Abstract

Abstract The principle of infrared thermal imaging is briefly described. According to the actual situation of the boiler and the investment cost, the location and quantity of the infrared cameras are analyzed, it is reasonable to set up an infrared camera on both sides of the end of the boiler grate for combustion monitoring. In addition, the thermal image of coal combustion in the boiler furnace monitored by the infrared cameras are analyzed and researched. It is concluded that the infrared thermal imaging technology can be applied to the combustion monitoring of coal-fired boilers, which is beneficial to saving coal, energy saving and environmental protection.
