摘要
为了对比研究350MW级超临界热电联产汽轮机抽凝机型与NCB机型的经济性,对该级汽轮机的两种机型进行热平衡方案计算,考察了典型纯凝与供热工况下两种机型的热耗率。结果表明NCB机型在供热工况下的供热能力及发电热耗率显著优于抽凝机型。
To contrast and investigate the Economy of extraction condensing and NCB-type 350 MW supercritical pressure cogeneration turbine, two kinds of turbine heat balance are calculated. The heating condition and the typical condensing heat consumption rate of the two type turbine are studied. The results indicate that heating capacity and power generation heat rate of NCB-type turbine under heating conditions is significantly better than extraction condensing turbine.
