摘　　要：建立了电站锅炉传递分析模型。参照工程传递评价准则,提出了传递过程、流密度火、用阻等评价指标,并且定义了传递系数,完成了对100 MW机组锅炉的传递分析。通过与常规的传热及分析比较,认为传递分析可以提供新的技术评价信息,从而对能量传递过程有更完整和全面的动态分析。The exergy transfer analysis model for utility boilers has been estabished. In the light of 〈〈Exergy Evaluation Criterion In Engineering〉〉 , the evaluation principle for exergy transfer, exergy flux density, and exergy resistance etc. has been put forward, and the exergy transfer coefficient being defined, the exergy transfer analysis for boilers of 100 MW unit being completed. Through com- parision with the conventional heat transfer and excergy analysis, it is believed that the exergy transfer analysis can provide new information about technical evaluation,thereby,the energy transfer can have a more complete and comprehensive dynamic analysis.
