1000MW超超临界二次再热燃煤发电示范工程总体设计方案
General Design of 1000-MW Ultra-Supercritical Double-Reheat Demonstration Power Plant
摘要
Abstract
In order to promote the energy saving and emission reduction,the Guodian Taizhou Power Plant Phase Ⅱ Project is built as the demonstration project of 1000-MW ultra-supercritical double-reheat coal-fired power generation units.In combination with the current technical levels of domestic coal-fired power plants and based on the comparison and analysis of foreign double-reheat coal-fired power generation units,this paper elaborates the selections of steam parameters and main equipments,the thermal system design,the auxiliary equipment selection and the air pollutant prevention design,etc.The practical operation of the demonstration project shows that the net coal consumption of the two units of this project has reached 266.57 g/(kW· h) and 265.75 g/(kW· h) respectively,while the dust,SO2 and NOx emission concentrations are lower than 5 mg/m3,35 mg/m3 and 50 mg/m3 respectively in standard state,indicating that the project has played a good referential and demonstrative role for the efficient and clean coal-fired power generation construction.关键词
