摘　　要：针对锅炉燃烧控制对象的大滞后特性,提出基于辐射能信号的燃烧控制系统优化方案。该方案利用红外辐射能信号快速反应炉内热量的特点,将其作为提前反馈量,接入DCS锅炉主控模块中,克服燃料侧干扰引起的锅炉主蒸汽压力及流量的波动,保证汽机运行的稳定性。通过闭环控制实施对燃烧的优化,能够提高机组的负荷响应能力。To deal with the large time delay of the object under boiler combustion control, the combustion control system optimization scheme based on radiant energy signal is put forward： the infrared radiant energy signal which can quickly reveal the heat within the furnace is used as the ahead feedback value and imported to the DCS, then the vi- bration of the main steam pressure and flow caused by disturbance on the fuel side can be overcome to ensure the sta- ble operation of the steam turbine. The load response capability of the unit can be improved through combustion optimization realized by closed loop control.
