摘　　要： 在余热双压发电系统中,压力式热力除氧器的除氧水箱兼做低压锅筒,中压系统做功工质取自低压系统,导致主、副汽参数存在复杂的内在耦合关系,使得主、副汽参数的调节存在相互干涉现象。明确主、副汽蒸汽之间存在最佳分配关系,是优化发电系统运行参数、提高系统发电效率的前提。以某余热发电系统为例,建立一定热源条件下余热锅炉主、副汽参数干涉模型,研究了主、副汽压力匹配对蒸汽参数、和效率的影响规律。论文的研究结果可以为余热发电双压锅炉主、副汽参数的运行优化提供指导。 In the waste beat double pressure power generation system, an oxygen removing water tank for a pressure type heat deaerator and a low-pressure boiler barre, and the medium pressure system works from the low voltage system, thus lead to the mutual interference phenomenon exist in main and vice steam parameters because of the internal complex coupling relation- ship between each other. The clear optimum energy distribution relationship between the main and auxiliary steam energy is the premise of optimizing the operation parameters and improving the efficiency of power generation system of power system. Take a waste heat power generation system as an example, the interference regularity of main and vice steam parameters matching for steam parameters, energy and energy efficiency was studied through establishing a Interference model of main and vice steam parameters under the condition of the waste heat holler. The guidance for optimizing operation of main and vice steam parameters in waste heat power generation boiler was provided by the research results in this pape.
