Operation optimization of new plasma ignition system of 1000MW ultra supercritical boiler

Abstract

Abstract: The structure features and the technical principle of the new plasma ignition system were introduced. According to the application of the system in the 1000MW ultra supercritical boiler of Guangdong Yudean Jinghai Power Generation Company Limited, the problems occurred in commissioning were analyzed. By the continual readjustment in practical operation, the operation parameter optimization scheme of the plasma ignition system was summarized. Thus, the arc interrupting phenomenon of the boiler plasma ignition system had been controlled effectively; and the safety of the boiler in start up, shutdown and normal operation was improved.

Key words: 1000MW ultra supercritical boiler, plasma ignition, operation optimization
