摘　　要：通过辅助汽水流量对发电标准煤耗率影响的强度矩阵,可以方便地分析各股辅助汽水流量的变化对煤耗率的影响程度,克服了传统算法繁杂、易错的弊病,为计算程序的编制提供了依据,也为火电机组节能降耗的分析工作提供了一种新的工具。以某再热机组为例,对强度矩阵的应用作了较为详尽的阐述,为正确运用强度矩阵提供了参考。Through the intensity matrix of the influence of the auxiliary steam-water on coal consumption, the influence of the auxiliary steam-water on coal consumption can be analyzed easily, which can overcome complexity and fallibility of traditional methods, offer basis to general thermal dynamic calculation program, and provide a new method to the analysis and calculation of the energy saving and consumption deduction for the coal fired power unit. Taking the reheat turbine as the example, this paper discusses the application of the intensity matrix in details, gives a reference to the intensity matrix utilization.
