At 13:50 on October 30, Unit 1 of the Biomass Cogeneration Demonstration Project in Zhaodong City, Heilongjiang Province, invested and constructed by China Energy Construction and undertaken by China Energy Construction Longjiang Energy Construction, was successfully connected to the grid for power generation, and the system of the unit was running smoothly and the parameters of each index were excellent. This is the first biomass project invested and constructed by China Energy Construction.
Zhaodong is located in Heilongjiang Province, south of the "ice city" Harbin, north of the "oil city" Daqing, is China's rare "cold black soil" green agricultural area. Zhaodong biomass cogeneration demonstration project is one of the "top 100 projects" in Heilongjiang Province, with a planned total investment of about 740 million yuan, two new 40 MW high temperature and ultra-high pressure primary reheat units, each unit is equipped with a 130-ton circulating fluidized bed boiler and a 40 MW suction condenser steam turbine power generation and heating unit, the fuel is mainly straw briquettes, which is the largest biomass cogeneration project of the same type in China. Longjiang Energy Construction is responsible for the construction, installation and construction of its construction and installation of the A lot - power plant area, the project Unit 1 was successfully connected to the grid to generate electricity, which is another green "straw" worked hard by Longjiang Energy in the alpine zone.
Rise to the occasion and secure nodes
Since the official construction of the Zhaodong biomass project, it has been affected by unfavorable factors such as the epidemic, typhoons, late arrival of equipment, and equipment defects. The project leadership team actively carried out psychological counseling work for the construction personnel, and at the same time strictly grasped the construction period to ensure the efficient performance of the project. The project leader goes deep into the front line every day to understand and grasp the progress of the project, and most of the problems that occur on the site are dealt with at the first time, and the remaining problems are solved at the weekly coordination meeting or special meeting.
In the process of blowing pipes, the main person in charge of the project adheres to the post to ensure that the node is completed on schedule and the shift system is implemented. Once, at 2:00 a.m., Sun Guoliang and Ni Jihui, who had just returned to the dormitory, received an emergency call from the sewage well that the amount of water was inverted due to the leakage of the valve, and immediately drove back to the scene to deal with the problem. At the same time, Yan Zhaoliang led the electrical team, and Liu Guojun led the steam engine team to actively organize drainage repairs, and did not return home until 4 a.m.
Affected by the epidemic, piling work was only started in mid-March this year, during which it was affected by the typhoon, causing a large area of water on the site, resulting in the inability to formally form the road in the factory, which caused great difficulties for mechanical entry and prefabricated pile entry. In this regard, the project department planned the piling route in advance and prepared the pile to facilitate the construction of the piling machine. Faced with a compact construction plan, the project department required the pile machine to work twice and arranged for the project department personnel to take turns on night shifts to catch up with the construction progress.
"Our employees are very much aware of the overall situation," Sun Guoliang said emotionally. "Each construction period node is completed on schedule, which is inseparable from the efforts of everyone in our team." The saline and alkali geology of the project department is easy to make the bearing capacity of the pile machine float greatly, resulting in difficult construction on site. Therefore, the project department adopts the method of measuring the height of each pile, records the pressure gauge reading of the pile machine and converts it into the bearing capacity of the pile machine, and after many on-site tests, improves the problem that the pressure stabilization time of the bearing capacity of the pile machine of the original plant is too long. On the basis of ensuring safety and quality control, Zhaodong Project Department has ensured and promoted the smooth realization of the construction period of important nodes.
Strive for excellence, and create fine products
From material entry testing, preparation work before construction, to all aspects of safe construction, and then to the smooth completion of each construction period node, a group of people in the project department strengthened the standardization leadership, focused on the requirements of quality engineering creation, and strived to create a modern construction site with reasonable planning, efficient and economical, digital and green integration, providing strong support for the construction of project quality projects.
Since the beginning of this year, the project has begun to operate and debug various equipment and systems, and the project leader often works until late at night, and the phone calls are answered all night long. In the face of the municipal water plant's water production standards, Sun Guoliang personally operated every time from sampling to sampling, and went to the water plant many times to negotiate until the chemical water successfully produced qualified water to ensure the normal operation of the boiler.
In addition, the project adopts the semi-dry desulfurization device of the circulating fluidized bed boiler, the high-efficiency bag filter, the low-nitrogen combustion technology, and the sncr denitrification process system for flue gas denitrification; in order to further reduce the environmental pollution caused by dust and noise in the factory area, the project also greens the plant area, and plants a large number of trees around the newly added structures to achieve the purpose of dust prevention, noise reduction and landscaping environment; the ash slag generated by the project will be fully utilized, including as raw materials for the production of cement and building materials, as agricultural fertilizer, etc. The concept of fine construction and green construction is vividly reflected here, and it also lays the foundation for the creation of high-quality projects.
Strengthen control and ensure safety
The project department conscientiously implements the "twelve in place", "334 project", "three-year rectification" and hidden danger investigation and judgment standards for the safety management of China Energy Construction, and with the joint efforts of all personnel, the safe production is maintained in a good situation of controllable, controllable and controllable, and there have been zero safety production accidents since the start of the project. Project manager Lin Chunqing performs one post and two responsibilities, personally leads the team to carry out safety inspections, rectifies the problems that can be rectified immediately, and issues rectification notices and require temporary protective measures for problems that cannot be rectified immediately. The Safety Supervision Department arranges special personnel to track rectification until the acceptance is qualified, and the main leaders and safety management personnel of the project department take turns to participate in the Monday safety meeting and the pre-shift meeting, summarize and deploy the weekly safety, conduct a hazard analysis of each day's operation, and formulate effective prevention and control measures for the identified risks.
"Our project has always been based on the construction goal of striving for high-quality projects, and has promoted the construction of the project in an efficient and orderly manner through model guidance, p6 project progress control, bim modeling, and smart safety." Lin Chunqing introduced. The project department uses the intelligent safety management system in combination with the general contracting unit, adopts face recognition, real-name system management of construction personnel, checks the personal information of the operators, etc., to achieve intelligent identity verification of personnel, and at the same time realizes the dynamic management of construction operations through video surveillance, AI violation recognition, tower crane monitoring and anti-collision system, etc., and uses advanced scientific and technological means to create a modern site management model to escort the completion of various production goals.
