The construction of the 1,320 MW (2x660 MW) Liaocheng Xiangguang ultra-supercritical (USC) coal-fired CHP project has started in Liaocheng, in the Shandong Province (China). The project is developed by a consortium comprising Harbin Power Group, Shandong Energy Group and Xinfengxiang Group. The thermal efficiency of the plant will be 61.8%, and the average annual coal consumption for power generation should reach 235 g /kWh. The project is expected to generate 6.6 TWh/year of electricity and 11.4 PJ/year of heat.
The project has three outstanding advantages: first, it is the world's first 600,000-kilowatt cogeneration project integrating ultra-supercritical, secondary reheat and other internationally advanced technologies.Second, the ultra-low energy consumption, an additional investment of 500 million yuan than the original plan, the use of secondary reheat technology, the thermal efficiency of the plant 61.81%, the comprehensive annual coal consumption of 235 grams/KWH can be significantly reduced coal consumption;Third, ultra-clean emissions. After the completion and operation of the project, the emissions of dust, sulfur dioxide and nitrogen oxides will be reduced by 40%, 42.86% and 30%, respectively, compared with those approved by the project eia, which are all better than the national standards for the limits of special emissions of air pollutants.
According to the Chinese National Bureau of Statistics, the share of coal in China’s primary consumption decreased by 1.5 percentage point in 2019 to 57.7%. China’s objective was to reduce coal’s share below 58% in 2020. China’s coal consumption and total energy consumption increased by 1% and 3.3%, respectively, in 2019. China’s NDC set the objective of achieving a peak CO2 reduction around 2030, or earlier if possible; lowering CO2 per unit of GDP by 40% to 45% from 2005 levels; and increasing the share of non-fossil fuels in primary energy consumption to around 20%.
