摘要
为提高循环流化床炉内脱硫效率以减小床温波动,采用反馈控制的脱硫燃烧系统,并针对其床温波动大的问题,加入床温变化率和炉内CaO含量以对其进行优化,得到基于前馈-反馈的优化控制系统。经对比仿真后,与实测数据相比,该优化控制系统能快速降低炉膛出口SO2的含量及其波动性,且可有效控制床温变化,改善床温波动,验证了该优化控制系统的脱硫效果好、成本低。
In order to improve the desulfurization efficiency and reduce bed temperature fluctuations in circulating fluidized bed furnaces,this paper first adopts a feedback controlled desulfurization combustion system.In response to the problems of large bed temperature fluctuations,the bed temperature change rate and CaO content in the furnace are added to optimize it,and a feedforward feedback based optimization control system is obtained.After comparative simulation,compared with the measured data,the optimized control system can quickly reduce the SO2 content and its fluctuation at the furnace outlet,and effectively control the bed temperature change,improve the bed temperature fluctuation,and verify the good desulfurization effect and low cost of the optimized control system.
