Huaze Aluminum Power's ultra-low emission retrofit project successfully put into operation

Recently, the successful start-up of Unit 3 of Shanxi Huaze Aluminum Power Co., Ltd. was successfully completed and put into operation. This signifies the successful completion of the ultra-low emission retrofit project for this unit. After the transformation, sulfur dioxide emissions were lower than 35 mg/m3, nitrogen oxides were lower than 50 mg/m3, dust content was less than 5 mg/m3, and all met the Shanxi provincial emission standards.

The 2×300 MW generating unit ultra-low emission engineering project is a key project for the implementation of ultra-low emission requirements of coal-fired generating units in Shanxi Province by Huaze Aluminum to carry out air pollution control projects. The total investment of the project is 160 million yuan, which is the company’s active social performance. The important manifestation of responsibility.

According to the person in charge of the company, in accordance with the government's guidance on encouraging third parties to govern, the two units of Huaze Aluminium Electric Co., Ltd. entrusted Harbin Boiler Factory Co., Ltd. with a BOT model to carry out ultra-low emission reforms. The reconstruction projects include seven sub-items of low-nitrogen combustion reformation, denitrification reformation, dry-type electrostatic precipitator reformation, reformed one-in-one wind turbine reformation, desulphurization reformation, increase of wet electrostatic precipitator, and expansion of ammonia area.

The ultra-low emission reform program for Unit 3 was officially started on August 23 last year. During the transformation, Huaze Aluminum Power established a project working group and compiled the construction plan, design plan, equipment and materials for each sub-item. Plan; conscientiously implement the project's overall network plan and set 35 goals.

In terms of quality management, the company rigorously reviewed the details of the construction unit's construction qualifications, special workers' certificates, inspections and inspections of construction machinery and equipment, etc. The construction plan was carefully examined and approved, and the supervision side station system for concealed works and key parts of the project was strictly implemented, and the project was executed conscientiously. The four-inspection system for acceptance inspection has a total of 319 inspection and approval batches, 295 sub-projects, 128 sub-projects and 39 unit projects. The acceptance rate of project quality is 100%, and the excellent and good rate is 95%. aims.

In terms of security and civilized control, the company has compiled the “Safety Management Approach for Ultra-low Emissions Projects” and the “Management Measures for the Comprehensive Assessment of Safe and Civilized Construction of Ultra-low Emissions Renovation Projects”. The management personnel implement one post with double responsibility and perform on-site inspections on a weekly basis. A security regular meeting is held once a week. During the construction process, the company promptly organized a special program review meeting for sub-projects such as demolition projects, anti-corrosion projects, and high-altitude lifting operations with major safety hazards, and set up full-time safety guards on-site monitoring according to the project management requirements for each type of operation. The construction personnel performed the safety technology disclosure prior to the commencement of work and seriously implemented various safety control facilities and measures.

In the process of intense construction, the company’s participating units have been co-ordinated, carefully deployed, carefully organized, seized with favorable opportunities, ensured the orderly progress of the project, and successfully completed the established goals of progress, quality, and safety control.
