摘要
文章以330 MW循环流化床锅炉在AGC调峰运行的方式为依据,通过管路运送石灰石,从而达到炉内脱硫目的,以此分析影响脱硫效果的几大原因。建立闭环控制系统,将上传到环保局监控的实际数值作为可控测量值。在原调节器的基础上手工建立二级调节器,从而形成具有自纠缠、自平衡、自动寻优的超级调节器。在进行了不断优化后,发现在长期投运过程中,可以实现超低排放的目标,这样既节省了石料,又极大地提高了经济效益,充分证明了该方案的可行性,既完善了PID调节器的性能,又为实现其他设备的自动化控制提供了思路。
Based on the operation of 330 MW in AGC peak regulation of circulating fluidized bed boiler,limestone is transported through the pipeline to achieve the purpose of desulfurization in the furnace,so as to analyze several reasons affecting the desulfurization effect.Establish a closed-loop control system to upload the actual value uploaded to the Environmental Protection Bureau as a controllable measurement value.Build the secondary regulator manually based on the original regulator,so as to form a super regulator with selfentanglement,self-balance,and automatic optimization.After continuous optimization,found that in the process of long-term operation,can achieve the goal of ultra-low emissions,which saves stone,and greatly improve the economic benefits,fully proved that the scheme has a good feasibility,improve the performance of PID regulator,and for the automation control of other equipment provides ideas.
