摘要
基于热力系统的分析计算方法,对1 000 MW超超临界机组应用补汽调节技术的设计方案以及经济性收益作了详细的论述及分析。结果表明:通过采用补汽调节技术,可使机组在额定负荷时主汽压力达到额定值,机组热耗降低约26kJ/(kW·h),经济性效果明显。
Based on the analytical calculation method for thermal system, detail calculation and analysis were conducted to the economy and design of a 1 000 MW ultra supercritical unit with additional steam control technology. Results show that after application of this technology, the pressure of main steam can reach the rated value and the unit heat consumption has been reduced by 26 kJ/（kW.h）, indicating obvious economy benefit.
