摘要
提出把遗传算法引入四角切圆煤粉锅炉燃烧的控制系统中,并采用了炉膛温度分布作为中间参量,以优化温度分布作为基本控制目标,在炉膛燃烧数学模型上进行仿真模拟。结果表明,采用炉膛温度分布为中间参量的遗传算法控制系统可以有效克服燃料发热量变化对炉内燃烧过程的影响,获得燃料量和风量控制指令以适应负荷的变化,并能给出个燃烧器故障情况下的识别和控制动作。
The genetic algorithm is introduced into an optimal control method for pulverized coal combustion in corner-fired boilers.The three-dimensional temperature distribution in furnace is used as an intermediate quantity,and its optimization is taken as a basic aim.The simulation has been done on a furnace combustion model.The results show that the control system with this algorithm can effectively overcome the impact of heat value variation of fuel on the combustion process,get the control signals of the fuel quantity and airflow rate to fit the change of load level,and identify and give control action under the failure of individual burner condition.
