摘要
文章对湖南省主要火电机组脱硫及脱硝自动控制系统的投运情况进行了全面调查,对其中最重要的脱硫吸收塔浆液pH值和脱硝氨气流量两个自动控制系统的控制策略进行了分析,指出了多数机组脱硫及脱硝自动控制系统中存在自动投运情况不佳、部分测点准确度较低、设备状况不理想、有设计缺陷等主要问题,并提出了有针对性的建议。
An investigation of FGD and denitration auto-control system for the main thermal power units in Hunan Province has been carried out in this paper, the control strategy of slurry pH control system of absorption tower and denitration ammonia flow control system has been analyzed. It has discovered that the problems existing in many units such as： the bad auto-control situation, the low control accuracy, the bad equipment condition, and some design defects. For these problems, some pertinent recommendations are proposed in this paper.
