简要分析华能玉环电厂4×1000MW超超临界燃煤发电机组及其控制特点,指出超超临界直流锅炉调节的关键是控制燃水比,阐述了超超临界燃煤发电机组的燃水比控制策略,并针对调试、投产后燃水比控制出现的问题提出了解决方法,取得了良好的控制效果。
The 4 × 1000MW ultra-supercritical coal-fired generating units in Huaneng Yuhuan Power Plant and its control characteristics are briefly analyzed. It is pointed out that the key point for the regulation of ultra-supercritical once-through boilers is to control the ratio of water to fuel, and the control strategy for the ratio of fuel to water in ultra-supercritical coal-fired generating units , And put forward a solution to the problems that occur after the commissioning and commissioning of the fuel-water ratio control, and achieved good control effects.
