摘要
分别采用传统[火用]分析法和先进[火用]分析法对某300 MW供热组进行了分析,计算了各部件的[火用]损、[火用]效率、[火用]损率、内源[火用]损、外源[火用]损、可避免[火用]损等参数,比较了各部件的可避免内源[火用]损率,并且研究了[火用]损在部件内部的分布。结果表明:通过采用先进[火用]分析法,得出供热机组的改进顺序依次为汽轮机、低压加热器、锅炉、凝汽器。采用先进[火用]分析法有利于结合具体部件设计供热机组的改进方法,减小系统[火用]损。
Analyses were conducted on a 300 MW heating unit through the traditional exergy analysis method and the advanced exergy analysis method,respectively,and following parameters of each component were calculated,such as exergy loss,exergy efficiency,exergy loss ratio,internal source exergy loss,external source exergy loss,avoidable exergy loss,etc.The avoidable internal source exergy loss rates of all components were compared,while the distribution of exergy loss within the component was researched.Results show that,by adopting the advanced exergy analysis method,the components of the heating unit for improvement are in order as follows:steam turbine,low-pressure heater,boiler,condenser.With the advanced exergy analysis method,it is helpful to design the improvement scheme based on the specific component,and reduce the exergy loss of the system.
