1000MW超超临界二次再热燃煤发电技术
Double-Reheat Coal-Fired Power Generation Technologies for 1000-MW Ultra-Supercritical Units
摘要
Abstract
To save primary energy,enhance environmental protection,reduce greenhouse gas emissions and improve the economic performance of power generation units,the Units 3 and 4 of Guodian Taizhou Power Plant Phase Ⅱ Project are independently developed,designed,manufactured and constructed as the demonstrative project of 1 000-MW ultra-supercritical coal-fired power generation technologies with double reheat cycles.This paper presents the general technical plans from the aspects of main parameter selection,boiler and steam turbine development,thermal system optimization,environmental protection technique integration and automatic control system development.The operation of the two units shows that the efficiency of the units have reached as high as 47.81％ and 47.95％ with the net coal consumption of 266.57 g/(kW· h) and 265.75 g/(kW· h) respectively.At the same time,the dust,SO2 and NOx emission concentrations have been reduced lower than 5 mg/m3,35 mg/m3 and 50 mg/m3 under the standard state,meeting and being better than the requirements of ultra-low emission.The successful commission and stable operation of the demonstrative project has laid solid foundation for the future development of clean coal-fired power generation technologies with higher parameters and better efficiency,accumulated valuable experience for the construction of the units of the same type and improved the competitiveness of China's coal-fired power generation technologies in the international market.关键词
