摘　　要：选取大型凝汽机组为主要研究对象,探讨不同负荷下初温、初压等主要运行参数变化对系统能耗的影响,以火电机组热经济性分析统一物理模型和数学模型为基础,建立初温、初压对煤耗影响的单因素扰动模型并对其进行定性分析。以求在热力系统能耗分析中,使计算过程更加快速、准确,计算模型可适应多种不同火电机组。Taking large condensing steam unit as the main studying object,impact of initial temperature and pressure on system energy consumption at different loads was discussed.The disturbance model about single influencing factor of initial temperature and pressure on coal consumption was built,based on the unified physical model and the mathematic model of heat-economic analysis for coal-fired power unit.It is hoped that calculation process is more rapid and accurate in analysis of thermal energy consumption,and the model can be suitable for various kinds of coal-fired power units.
