Recently, the energy-saving and low-carbon renovation has been successfully carried out for the Unit#7 of Zouxian 1000MW Coal-fired Power Plant by SEPCO1, and the Unit has been put into operation. Till now, the Unit has run smoothly and recorded excellent vibration parameters of each bearing bush. The safety management, quality control, construction schedule, epidemic prevention and control of the project have gained the full recognition by the Owner. It is reported that the technical renovation of Unit#7 in Zouxian 1000MW Coal-fired Power Plant is the first one of projects requiring renovations in respect of energy-saving and low-carbon, flexibility and heating supply, which are to be implemented by Shandong Branch of China Huadian Corporation Ltd. in 2022. There are three main lines in the work,i.e. the flow path retrofitting of steam turbine, the optimization of boiler combustion equipment, flow field of flue gas and air system and the modification of DCS, which includes 1596 standard items, 107 special projects, and 42 technical renovation items. The completion of the renovation work not only greatly improves the clean production capacity of the 1000MW units, but also has attached great significance to taking aim at the dual-carbon goal and exploring the path of high-quality development of existing 1000MW coal power units. According to the analysis on current operation data, after the renovation of Unit 7, the coal consumption of power supply can be reduced by more than 20g/kW·h, about 100,000 tons of standard coal can be saved every year, and 262,000 tons of carbon dioxide emission can be reduced. All the indexes on energy consumption and environmental protection have reached the leading level in China. |
