The #1 boiler in the power center of Guangdong Petrochemical’s integration project was successfully ignited
Thread Content
On April 26, Boiler No. 1 in the power center of the Guangdong Petrochemical Integration Project, constructed by Huanqiu Company, was successfully ignited. This laid the foundation for subsequent pipeline purging and turbine commissioning, marking the transition of the power center from the construction phase to the production startup phase. The power center is the source of ultra-high pressure steam power for the entire project; it includes 4 high-temperature, ultra-high pressure gas boilers with a capacity of 450 tons per hour, as well as 3 turbine generator sets. It is equipped with environmental protection facilities for flue gas denitration to ensure ‘clean’ flue gas emissions, and it plays a key role in the operation and commissioning of the project.
The power center was overall contracted by Global Company’s PC department, with Global Guangdong Company and Global Jilin Chemical Construction carrying out the work jointly. Construction of the project officially began on March 15, 2020. The excavation of the chimney foundation took place on May 15, pile foundation construction was completed on July 10, and the installation phase started on September 14. It thus became the first key component of the entire project to commence on-site work after the outbreak of the COVID-19 pandemic, the first to have its steel structure installed, and the first to enter the full equipment installation stage. On March 6, 2021, the 150-meter chimney of the Power Center was successfully completed, becoming a new landmark for the entire plant. Once the boiler installation entered its full-scale phase, issues such as limited construction space, frequent concurrent tasks, numerous high-altitude operations, and the impact of the pandemic on material supply arose one after another, posing significant challenges to on-site construction. To ensure the efficient and orderly progress of the project, Global Company makes full use of the advantages of its \"headquarters-subsidiary\" structure, integrated resource management, and general contracting capabilities. It actively promotes the implementation of the \"six modernizations\" approach, adopting \"factory-prepared components and modular installation\" methods to effectively improve work efficiency on site. To address issues such as the close spacing of the boiler water wall tubes, the difficulty in welding them, and the tendency for deformation during lifting, Huanyu Company adopted ground-based alignment and welding methods, as well as lifting in batches, thereby reducing the need for work at heights and the number of crane shifts required. To ensure welding quality, Global Company has vigorously carried out special initiatives such as comprehensive inspections and rectifications, as well as a 100-day campaign focused on safety and quality. It has firmly established the principle that development must not come at the expense of safety, adhering to strict safety standards. The company takes both production and epidemic prevention measures seriously, formulates detailed emergency plans, organizes safety drills in advance, and conducts thorough inspections of key areas such as boiler pipes and sealing welds. Through daily, weekly, monthly inspections as well as specialized checks, the first-pass welding success rate has reached 99.22%. After more than a year of hard work, Boiler No. 1 passed its hydrostatic test on August 14, 2021, on the first attempt, and by October 31, all four boilers had completed their hydrostatic tests with high quality.
Boiler No. 1 passed its hydrostatic test successfully on August 14, 2021, and on October 31, all four boilers completed their hydrostatic tests with high quality. The boiler water pressure needs to be stabilized for half a year before ignition – what other tasks are there in between? ? ? ? ?

Going all out, heading towards 630 to feed materials and start the machine.
Can the pipeline purging and turbine startup be completed in two months? ? ?
Not necessarily; you can use the reverse driving method.
This is likely for the boilers across the entire plant; for the oil refining and chemical sectors, the boilers can first be used to produce steam for purging in Central Asia
Yes, the power island of the plant’s utility center.
