摘要
利用某电站锅炉的运行数据,建立了基于改进遗传算法的锅炉效率优化模型,显著改善了遗传算法的稳定性,应用该方法和模型对锅炉效率优化。计算分析表明:通过平均氧量、顶排二次风挡板开度和中排周界风挡板开度的调整,锅炉效率升高0.44%。
Based on the operation data of power plant boilers,the present study improves the classical genetic algorithm and establishs the model to optimize the efficiency of power plant boilers.This model significantly improve the calculation stability of the genetic algorithm.Through the adjustment in the mean oxygen,openness of secondary air damper at the top position and surrounding air damper in the middle position,the boiler efficiency is improved by 0.44%.
