中文摘要: 对现有常规热电联供方案进行了研究,发现其在较低电负荷或较大热负荷时,增加了节流损失、回热系统损失和余速损失。提出并研究了在低压缸进汽支管上配置调节阀的"虚拟"切缸方案以缓解上述损失。通过一次及二次再热机组实例进行了计算定量分析,结果表明,"虚拟"切缸方案机组经济性更优。
Abstract:By studying the existing conventional combined heat and power scheme,the throttling loss,regeneration system loss and exhaust loss are increased at lower power load or greater heat load.The scheme that valve arranged on the inlet branch of the low pressure casing was researched to alleviate the above losses.Examples of single reheat unit and the double reheat unit were analyzed and this scheme was more efficient.
