摘要
对燃煤机组进行深度调峰和灵活性改造,提高电网对可再生能源的消纳能力,落实绿色发展政策,是我国火电机组的发展方向。脱硝系统在所有环保设备中的控制难度和对下游设备的安全隐患最大。针对脱硝系统,从设计和设备选型角度出发,对工艺、控制、烟温提升等方面改进优化探讨,涉及流场、氨空混合系统、CEMS仪表测量及配置、烟气旁路注入结构及挡板门叶片形式、烟温测点等方面,为各电厂提供改造思路。最终实现机组深度调峰安全、稳定、经济运行。
In order to enhance the consumption capacity of renewable energy and implement the policy of environmental development,carrying out the transformation of flexibility and deep peaking on coal-fired power plants has became a trend in the future.Among all the environmental protections,denitration system is the most difficult to control.In this study,different design optimization measures and equipments selection from the point of technology,auto-control and the gas temperature improvements are discussed firstly,including flow field,ammonia and air mixing system,CEMS system,the gas bypass and so on.which is able to provide ideas for power plants.
