摘要
对基于某化工厂自备电厂两台25兆瓦抽汽发电汽轮机组抽汽、凝汽比例改变引起机组效率和供电标准煤耗变化等进行了定量分析,建立了数学模型,计算出对应的供电标准煤耗,并绘出性能曲线。根据机组计算结果,指出了影响机组运行经济技术指标的因素,提出了蒸汽系统设计、生产运行的优化方案。
The article emphatically gives a quantitative analysis of the generating unit efficiency and power supply standard coal consumption variation resulting from the extraction condensation ratio change of two 25Mw extraction turbine generating units in a certain chemical plant self-supply power plant and sets up a mathematic model.Corresponding power supply standard coal consumption is calculated based on this model and the characteristic curve is also drawn.In the light of the calculation results of the generating units,it points out the factors affecting the economic and technical indexes of the generating units’ operation and puts forward the optimization scheme for the steam system’s design and productive operation.
