Datang Dongying Power Generation Project
Datang Dongying Power Generation Project Phase I built two million-kilowatt ultra-supercritical coal-fired power generation units with a total investment of 9.154 billion yuan. It is a key energy project in "Shandong Peninsula Blue Economic Zone Development Plan" and "Yellow River Delta High-Efficiency Ecological Economic Zone Development Plan".
Datang Dongying Power Generation Project is featured by high parameters, large capacity, and new technology. It adopts a number of integrated innovative technologies for the first time in the world and is the first case in China. The designed power supply coal consumption is 258.72 g/kWh, the plant power consumption rate is 3.88%, and the plant thermal efficiency is 49.4 %, the best among 1,000MW thermal power units in the same period. The steam turbine uses single-axis, six-cylinder six-exhaust, with an ultra-long axis of 59.627 meters. Compared with traditional five-cylinder four-exhaust 1,000MW steam turbine, it effectively reduces the heat loss. The boiler adopts domestically advanced ultra-supercritical secondary reheating tower furnace with an efficiency of 94.9%; seawater desalination technology is applied, which can save more than 2 million tons of fresh water each year. The project simultaneously constructs environmental protection facilities such as desulfurization, denitrification, ash removal, dust removal, and sewage treatment facilities with sulfur dioxide, nitrogen oxides, smoke and dust emission concentration and other indicators reaching the design value, lower than the national ultra-low emission standards. It also achieved zero discharge of wastewater, setting a precedent for 1,000MW secondary reheat coal-fired power plant with higher energy efficiency and environmental protection.
