1000MW超超临界机组双层等离子点火系统运行优化

Operation Optimization of Double Layer Plasma Ignition System of 1000 MW Ultra Supercritical Unit

介绍了双层等离子点火系统在1 000 MW超超临界锅炉的首次应用情况,分析了调试过程中的诸多措施。与常规油枪和单层等离子启动相比,双层等离子点火启动最经济,可实现锅炉无油点火启动,减少了点火初期排放大量烟尘对环境的污染。

The application of the double layer plasma ignition system on 1 000 MW ultra supercritical boiler was introduced in this paper,and various measures in the process of commission were analyzed. Compared with the conventional single layer plasma ignition and oil gun start,double layer plasma ignition was the most economical,and could realize the oil-free ignition start of boiler,reduce smoke pollution to the environment during the ignition stage.
