中文摘要: 为了比较新建660 MW机组一次与二次再热机型优劣，以安徽某电厂二期扩建工程2×660 MW机组为对象，拟定方案1与方案2。通过技术经济性比较发现，方案1较方案2的总投资虽高约38 201万元，静态投资回收期为10.3a，但节煤效果更好，全厂每年可节约标煤约5.4万t（按假定的负荷模式运行），并减少二氧化碳排放约7万t。
Abstract:In order to compare the advantages and disadvantages of primary reheat model and secondary reheat model of newly-built 660 MW Unit,targeting at 2×660 MW Unit of a power plant in Anhui,scheme 1 and scheme 2 are proposed.Through technical and economic comparison,the total investment of scheme 1 is about 382.01 million yuan higher than that of scheme 2,and the static investment payback period is 10.3 years,but the coal saving effect of scheme 1 is better.The whole plant can save about 54 000 of standard coal every year (according to the assumed load mode) and reduce carbon dioxide emission by about 70 000 t.
