以300 MW机组为例,建立由太阳能、生物质能组成的辅助热源作用于燃煤机组回热系统加热器汽侧的(火用)损矩阵模型,利用该模型分析原机组回热系统中各加热器的节能潜力,确定辅助热源的高效引入位置,研究新能源辅助燃煤混合发电系统的汽轮机(火用)效率、标准煤耗率降低量等热力性能指标.结果表明:5#低加、2#高加是节能潜力最大的加热器,100％负荷下混合发电系统的经济效益最好,辅助热源作用于2#高加混合发电系统的经济性优于5#低加,并随分流系数增大,热力性能指标均升高;当分流系数增至完全排挤汽轮机抽汽各指标最大值时,全厂及汽轮机(火用)效率提高率分别达6.31％、6.71％,标准煤耗率降低量达17.87 g/kWh.
