摘要
推导了三压无再热的余热锅炉排气温度 t A2 的计算关系式 ,并探讨了各种因素对 t A2 的影响。在此基础上研究了余热锅炉的当量效率 ηh 与汽轮机循环有效效率 ηst之间的优化匹配关系。由此可以来优化选择汽轮机的主蒸汽、中压蒸汽与低压蒸汽的压力和温度参数。
In this paper,some equations for calculating the gas exhaust temperature from triple pressure non-reheat HRSG t A2 were derived,then the influences of many different factors on t A2 and the optimal matching relationship between the equi volant efficiency of HRSG η h and effective efficiency of steam turbine cycle η st were studied in detail,by which the optimal parameters of pressure and temperature of high pressure,medium pressure and low pressure steam for HRSG can be selected correspondingly.
