At 20:18 on July 1st, the No. 3 unit of the Guangdong Guoyue Shaoguan Comprehensive Utilization Power Generation Expansion Project, which was undertaken and tested by the Debugging Institute affiliated to the company, successfully passed the 168 - hour full - load trial operation. This milestone event marks the official completion and commissioning of the first (set) demonstration project in China‘s energy sector in this phase. The project adopts the world‘s largest single - unit capacity "700MW ultra - supercritical circulating fluidized bed boiler" technology, which has the advantages of efficient and clean utilization of inferior fuels and ultra - low emissions. Its successful commissioning is of great significance for promoting the optimization of the local energy structure and boosting the sustainable economic development.​
The total investment of the Guangdong Guoyue Shaoguan Comprehensive Utilization Power Generation Expansion Project reaches 3.01934 billion yuan. The construction content includes 1 × 700MW high - efficiency ultra - supercritical circulating fluidized bed coal - fired generating unit, as well as supporting auxiliary, public and environmental protection projects, etc. The project is located in the reserved development land of the existing factory area of Guoyue (Shaoguan) Power Co., Ltd. at No. 33 Yuanxiang Road, Dongguan (Shaoguan) Zhenjiang Industrial Transfer Park, Shaoguan City, Guangdong Province, covering an area of 16.87hm². The commissioning of this project will effectively improve the power supply capacity of Guangdong Province and northern Guangdong, and at the same time provide stable energy support for the Shaoguan data center cluster, a national hub node of the national integrated computing power network in the Guangdong - Hong Kong - Macao Greater Bay Area.​
In terms of technological innovation, the "700MW ultra - supercritical circulating fluidized bed boiler" technology adopted in this project is at the world‘s leading level. Through four core technologies: ultra - low emission at the furnace outlet, no external bed design, series hydrodynamic system and water wall water supply protection system, it realizes the efficient and clean utilization of inferior fuels and meets the strict requirements of ultra - low emissions. Compared with units of the same capacity, the boiler thermal efficiency of this project is higher, which can save 5 grams of standard coal consumption per kilowatt - hour, greatly improving energy utilization efficiency and reducing operating costs.​
In terms of environmental protection, the project strictly complies with the relevant regulations of national and Guangdong Provincial ecological environmental protection, ensuring that the construction and operation meet the requirements of Shaoguan‘s high - quality green development. The project has no new production wastewater discharge. The flue gas of the 700MW high - efficiency ultra - supercritical circulating fluidized bed boiler complies with the standard limit requirements for coal - fired boilers in Table 1 of the "Emission Standards for Air Pollutants from Thermal Power Plants" (GB13223 - 2011). The emission concentrations of soot, sulfur dioxide and nitrogen oxides meet the ultra - low emission requirements, making a positive contribution to local environmental protection.​
In terms of economic benefits, after the project is put into operation, the annual output value is expected to reach 2.5 billion yuan, with about 300 new jobs created and annual tax revenue of about 80 million yuan, which will strongly promote local economic growth and drive the improvement of employment and tax revenue. At the same time, the project uses the abundant local gangue resources mixed with raw coal for power generation, which not only realizes the comprehensive utilization of resources, but also solves the pollution problem of gangue, with significant environmental and social benefits.​
The Debugging Institute has played a key role in the project construction. The project department responsible for the sub - system and complete set debugging of Unit 3 adheres to the concept of "debugging integration, scientific management, stable operation upon commissioning, and continuous service", takes refined debugging as the core, standardized operation as the starting point, and high - standard start - up as the guarantee, and has achieved the goal of "high - standard debugging, high - quality acceptance, and high - level commissioning". During the whole set of start - up process, the project department strictly implemented various debugging specifications and requirements, closely cooperated with various co - construction units, made every effort to do a good job in safety supervision, closely monitored the unit operation, and orderly promoted various tests to ensure the stable operation of all systems and equipment of the unit and the excellent performance of main operating parameters.​
In the future, the Guangdong Guoyue Shaoguan Comprehensive Utilization Power Generation Expansion Project will continue to play its positive role in energy supply, environmental protection and economic development, injecting strong impetus into promoting the sustainable development of the local area and even Guangdong Province. With the stable operation of the project, its advanced technology and management experience will also provide valuable reference for the development of the national energy sector.
