The air-cooled dry-type slag discharge machine "smart slag discharge" collects operating condition data inside the slag hopper through the introduction of optimized video surveillance image recognition, 3D material level recognition, thermal imaging temperature field recognition and other technical means. Simultaneously connect the intelligent recognition control system for operating parameters and couple it with the boiler combustion optimization system. Through "smart slag discharge", the intelligent opening and closing of the dry slag mechanism can be achieved, automatically adapting to the current operating conditions, improving operational safety, reliability, economy, and environmental protection, and enhancing the digital and intelligent development of power plant auxiliary equipment.
