Nantong Cement SCR Denitrification Transformation Project Put into Operation!

of Nantong Cement Technology Department is mainly responsible for the promotion of technical transformation projects and equipment maintenance of Nantong Cement Plant, and the Party Branch has always stood on the front line of production guarantee and technological innovation. In 2025, facing the increasingly stringent environmental protection requirements of the state, the Party branch of Nantong Cement Technology Department took the SCR denitrification transformation project of kiln tail flue gas as the key technical transformation task of the year, gave full play to the role of the Battle Fortress, led the whole process of the project with the mode of "Party building plus", and led all members of the Party branch to face difficulties and concentrate on tackling difficulties. This hard task with complex technology and urgent construction period has been completed safely and successfully, and the professional responsibility of the technical department has been demonstrated in the main battlefield of technological transformation.

Party branch personally took the lead, coordinated the overall situation, held several special branch committees and Party congresses successively, unified ideas, gathered consensus, deeply studied and comprehended the spirit of General Secretary Xi Jinping's important expositions on the construction of ecological civilization, conveyed and implemented the deployment requirements of the Party committees at higher levels on green development, and promoted the construction of ecological civilization. Guiding all Party members to understand and devote themselves to the project construction from a political point of view has laid a solid ideological and organizational foundation for the smooth start and promotion of the project.

, the Party branch secretary serves as the group leader, and technical backbone Party members of various specialties are transferred to form the" SCR Project Party Member Tackling Team "to strengthen the" backbone "for tackling key problems. The group implements weekly meeting and monthly summary system, which becomes the "core center" of project technical decision-making, resource coordination and problem solving. Branch secretaries insist on commanding ahead, go deep into the construction site regularly, grasp the first-hand situation in time, coordinate and solve more than ten difficult problems across departments and specialties, and ensure the efficient operation of the command system.

In view of the key areas such as process optimization, equipment installation, civil construction and safety supervision, the Party branch has precisely set up a "demonstration post for Party members", requiring Party members to "show their identity, responsibilities and commitments". Under the leadership of Party members in demonstration posts, the working standards of all links have been strictly implemented, and the responsibility has been implemented to the "last meter". During the peak period of equipment installation, Party members in demonstration posts took the lead in giving up holiday breaks and sticking to the site in shifts day and night to ensure the progress and quality of installation. A

special "safety supervision group" with Party members and security officers as the core has been set up to formulate a special safety management plan. The supervisory group carried out dozens of routine inspections and special inspections, organized 12 special safety training and disclosure sessions, investigated and rectified more than 50 potential safety hazards, realized "zero accidents, zero casualties" throughout the project construction, and built a solid safety barrier for the smooth completion of the project.

role models drive benchmarking.". A "vanguard list of Party members" was set up at the construction site to publicize and commend the advanced figures and deeds emerging in overcoming difficulties in real time. Comrade Huo Yansheng, a Party member, creatively proposed a streamlined operation scheme for the production of SCR middle box and reactor, which effectively overcame the limitations of the site and saved the construction period by 7 days. Lou Fangjin, a Party member safety officer, investigated the hidden dangers of high-altitude operations with a "golden eye" and effectively avoided possible safety accidents. The deeds of these examples have greatly stimulated the enthusiasm of all the participants.

Draw on the wisdom of the masses. Actively carry out the "I offer a policy for emission reduction" campaign, widely solicit the opinions and suggestions of front-line workers, especially Party members and technicians, and receive and adopt more than 30 rationalization proposals. This not only optimizes the technical scheme, but also creates a strong atmosphere of "everyone cares about the project, everyone participates in the project", forming a strong joint force of collective efforts to overcome the difficulties.

Clean escort clean atmosphere. Integrity construction will be carried out throughout the project, and the branch committee will participate in the acceptance of key nodes throughout the project. To formulate and strictly implement the List of Project Integrity Risk provention and control, strengthen the sense of discipline and discipline of all project personnel through honest and clean government talks and warning education, ensure the operation of the project in the sunshine, and achieve the goal of "high quality of the project and excellent cadres".

Party members are brave in innovation in actual combat, and put forward a number of optimization suggestions with significant benefits: the process transformation of SCR ash conveying system avoids the risk of equipment accidents; the improvement of flue gas pipeline valves for waste heat power generation reduces air leakage and heat loss; the optimization of compressed air pipeline laying effectively prevents filter bags from pasting. These technical highlights not only solve practical problems, but also enhance the technical content of the project. At the same time, the standardized work flow of "Party building + project" formed by the project provides replicable management experience for the follow-up major technological transformation projects. After the project is put into operation, all indicators meet the national ultra-low emission standards after third-party testing, and it is estimated that about 800 tons of nitrogen oxides can be reduced annually, with great environmental benefits. Through the successful practice of SCR denitrification project, the Party branch

of Nantong Cement Technology Department has proved the feasibility and effectiveness of ensuring high-quality development with high-quality party building. In the next step, the branch will continue to summarize and promote the working mode of "Party building + project tackling", constantly improve the long-term mechanism of deep integration of Party building and business, and contribute more to the company's new journey of "strengthening reform and achieving goals".
