摘　　要：以安徽新建某电厂2×660 MW机组为对象,分析了设置邻机蒸汽加热项目功能与特点,提出了邻机蒸汽加热项目设计方案。此项目实施后2台机组初投资增加90万元,每年2台机组综合节省费用20.76万元,按照贷款利率7.05%计算,项目投资回收期在8年以内,小于10年,项目可行。In order to demonstrate the technical economy of 660 MW unit adjacent unit steam heating project, taking 2×660 MW Unit of a newly built power plant in Anhui Province as the object, the function and benefits of setting adjacent steam heating project are analyzed, and the design scheme of adjacent steam heating project is proposed. After the implementation of the project, the initial investment of two units increases by 900 000 yuan, and the comprehensive cost saving of two units is 207 600 yuan per year, according to the loan interest rate of 7.05% calculation, the payback period of the project is within 8 years, less than 10 years, the project is feasible.
