摘要
为了提高特殊汽轮机组的整体经济性水平,以55 MW级垃圾焚烧发电汽轮机组为研究对象,采用提高主汽压力和抽汽再热循环的措施,定性研究了不同再热汽源抽汽点的位置、再热温度和再热压力对机组经济性的影响,计算了不同方案下的热力性能。结果表明:提高主汽压力并采用抽汽再热循环可大幅提高机组的经济性水平;在相同锅炉吸热量下,方案3和方案4的机组出力比方案1分别高5.46%和6.61%,方案4的机组出力比方案3高1.15%。
In order to improve the overall economic level of special steam turbine units,taking a 55 MW level waste incineration power generation steam turbine unit as the research object,by increasing the main steam pressure and the extraction reheat cycle,the effects of the location of different reheat steam source extraction points,reheat temperature and reheat pressure on the economic performance were qualitatively studied,and thermal performance under different schemes was calculated.Results show that increasing the main steam pressure and adopting the extraction reheat cycle can significantly improve the economic level of the unit.Under the same boiler heat absorption,the unit output of scheme 3 and scheme 4 is 5.46%and 6.61%higher than that of scheme 1,respectively.The unit output of scheme 4 is 1.15%higher than that of scheme 3.
