摘要
研究了联合循环条件下双压无再热非补燃和补燃式余热锅炉的当量效率、蒸汽轮机循环有效效率和联合循环热效率之间的优化匹配关系,由此来进行蒸汽高低压力参数选择与机组的优化匹配,确定了最佳参数。并在此基础上阐述了余热锅炉补燃对联合循环热效率的影响。
Analysis double pressure non reheat with afterburning and non afterburning HRSG to optimize the matching relation between the equivalent efficiency of the HRSG, steam turbine cycle efficiency effectively and combined cycle thermal efficiency under the condition of the combined cycle, thereout select to optimize the matching relation between high and low steam pressure parameter and unit, make sure the best parameter, on this basis elaborate the influence of the afterburning HRSG to the combined cycle thermal efficiency.
