en.Wedoany.com Reported - In the central control rooms of waste incineration power plants, operators long faced issues with drastic fluctuations in the calorific value of incoming waste and unstable combustion conditions. This not only led to fluctuations in steam output and reduced power generation efficiency but also risked causing instantaneous exceedances of pollutant emission standards. In a medium-sized incineration plant, operators had to manually intervene in the combustion process hundreds of times daily on average.
Now, a domestically developed system is changing this situation. China Everbright Environment has successfully developed the Adaptive Intelligent Combustion Control System (ACC), equipping waste incineration equipment with a precise and efficient "AI brain," achieving a shift from "manual experience-based operation" to "artificial intelligence precise control." After multiple iterations, this technology has been applied at scale across dozens of projects and over a hundred incineration lines under Everbright Environment.
The Guangdong Boluo Waste-to-Energy Plant is the first demonstration project for Everbright Environment's ACC system. Before the system was deployed, operators manually intervened in the combustion process hundreds of times daily, with on-duty personnel required to monitor the central control room throughout their shifts. After deployment, the frequency of manual intervention was reduced by over 97%, achieving normalized 72-hour unattended operation and setting an industry record of 192 hours of continuous automatic operation, with process parameter curves remaining stable and continuous.
The core technology of this system lies in three innovations: First, precise intelligent sensing technology, which employs specialized radar detection equipment in the high-temperature core zone of the incinerator to achieve non-contact measurement with 0.1‰ accuracy, providing a basis for precise feeding. Second, big data predictive regulation, which leverages massive operational data to build intelligent analysis models, anticipates fluctuations in waste calorific value in advance, and automatically adjusts air intake volume and grate speed accordingly. Third, fully automated collaborative control of the entire process, which uses intelligent algorithms to coordinate and regulate multiple stages such as feeding, grate operation, and ventilation air distribution, ensuring stable combustion and compliant flue gas emissions.
To date, the ACC system has been applied across dozens of projects and over a hundred incineration lines under Everbright Environment, adaptable to the full range of its self-developed grate furnace types with capacities from 300 to 1,000 tons/day. Following system deployment, the automatic control utilization rate for feeding and grate operation has increased, boiler load fluctuations are stably controlled, the frequency of instantaneous carbon monoxide exceedances has significantly decreased, and the loss on ignition of slag is stably maintained at a low level. The system effectively reduces reliance on manual labor, becoming a core support for cost reduction and efficiency enhancement in waste incineration plants.
Facing new challenges as the industry expands towards "solid waste+" and multi-fuel co-combustion, the ACC system continues to iterate and upgrade, progressing from the automatic control foundation of version 1.0, through the practical experience accumulation of version 2.0, to version 3.0 which builds comprehensive perception with "3D radar + image recognition," continuously solving problems under extreme operating conditions.
Currently, this technology has obtained 44 authorized intellectual property rights, including 8 invention patents. The key technology has been incorporated into the national standard "Technical Standard for Municipal Solid Waste Incineration Treatment and Energy Utilization Engineering." Using the ACC system as a fulcrum, Everbright Environment is driving the intelligent upgrade of the environmental protection industry and will continue to deepen the integrated innovation of "AI + Environmental Protection" in the future, expanding the application scenarios of artificial intelligence across the entire solid waste treatment chain.
