摘要/Abstract

摘要： 联合循环电站采用的重型燃气轮机在启动以及低负荷阶段普遍存在冒黄烟现象，其中承担调峰工作的机组问题尤为突出。初步判断，冒黄烟是由于低负荷工况下烟气中NO₂含量升高所致。为进一步理清燃气轮机黄烟生成机理，有效地控制低负荷工况下烟气中NO₂含量，以GE公司6F.03燃机为研究对象，针对燃机启动阶段，采用现场烟气测试的方法对余热锅炉内部不同位置烟气成分进行监测，并对比分析黄烟生成的影响因素，最后从燃机侧和余热锅炉侧提出了重型燃气轮机抑制黄烟的对策及治理措施。

Abstract: The emission problem of yellow plume generally occurs at the combined cycle power plants where the heavy-duty gas turbines is installed and operated during the turbine start-up process or under low load conditions. It becomes even worse especially for those units actively participating the peak load regulation. It is found out that yellow plume is caused by the rising NO₂ concentration in flue gas. In order to further understand the formation mechanism of yellow plume in gas turbines for the purpose of more effective control on the content of NO₂ in flue gas under low load conditions, the authors took GE 6F.03 gas turbine as the research object and implemented the method of field flue gas testing by measuring the flue gas composition at different positions in the heat recovery steam generator (HRSG) at the start-up stage of gas turbine. Then the factors affecting yellow plume generation were analyzed and compared. Finally from the gas turbine side and the heat recovery steam generator (HRSG) side, the countermeasures and detailed control procedures for heavy gas turbine to suppress yellow plume are put forward.
