摘要
Abstract
The emission of NOx decreased obviously after the transformation with low NOx burner (LNB) for a 600 MW unit.However,there are some problems during the process in operation,such as overheating of the reheater,the high oxygen deviation and the high NOx emission under high power loads.The problems are discussed in this paper and some improvement measures are proposed to ensure the efficiency and safety of LNB.关键词
