660 MW机组增加0号高加项目技术经济性分析

Analysis of the Technical and Economic Properties of No.0 High Technology Project of a 660 MW Unit

为考查增加0号高压加热器项目在安徽某新建2×660 MW工程中的技术经济性,先拟定增加0号高加项目具体方案,然后通过投资回收期法计算表明,75%THA工况下发电标准煤耗降低0.88 g/(k W·h),50%THA工况发电标准煤耗降低0.73 g/(k W·h),每台机组年节约标煤2 243 t,每年节约标煤费用164万元,每台机组投资约600万元,按静态投资回收期计算不到4年就可收回投资,所以技术经济性良好.

In order to evaluate the technical and economic properties of No. 0 high project of a new 2 × 660 MW project of Anhui Province, a new 2 × 660 MW Engineering Project No. 0 high increase of specific program is firstly developed. The calculations achieved by using payback period method show that the standard coal consumption rate of power generation decreases by 0. 88 g/（ k W·h） and 0. 73 g/（ k W·h）,respectively,under 75% THA conditions and 50% THA. That is to say,for each unit,2 243 tons of standard coals are saved annually,namely,1 640 000 yuan of standard coals. An investment of 6 million yuan of a unit can be recovered in less than 4 years according to the calculation of the static payback period,showing that the project is highly technical and economic.
