通过辐射能信号能够更加直接地反映燃料量或者燃烧品质的改变。采用基于辐射能信号的锅炉燃烧调节系统设计思想,通过对常用的几种锅炉燃料控制系统的分析比较,表明提出的以主蒸汽压力为主调参数、以炉膛总辐射能为副调参数的串级燃烧控制策略是可行的。仿真实验研究以及开原热电厂的实际控制效果证实了该方法的实用性和优越性。
The change in fuel quantity or combustion quality can be reflected more directly by the radiant energy signal. Adopting the design idea of boiler combustion control system based on radiant energy signal, the analysis and comparison of several commonly used boiler fuel control systems show that the proposed main steam pressure is the main tuning parameter, and the total radiant energy of furnace is the secondary tuning parameter Level combustion control strategy is feasible. The simulation experiment and the actual control effect of Kaiyuan Thermal Power Plant confirm the practicability and superiority of this method.
