摘　　要：全面定性分析系统不明泄漏对煤耗指标计算的影响,指出综合考虑系统不明泄漏对汽轮机热耗率、锅炉效率和管道效率三者的影响,能够最大限度的弱化试验人员通过主观分配系统不明泄漏在炉侧分配比例的方式"主导"煤耗计算结果,有利于常规热力性能试验中客观评价机组能耗水平。实例验证了方法的可行性。A comprehensively qualitative analysis of the unaccounted - for leakage of system used in the coal consumption calculation is given. It is pointed out that comprehensively analyzing the effect to heat rate, boiler efficiency and pump efficiency caused by the unidentified leakage of system, can weaken the coal consumption calculation result to the maximum limit, which is dominated by testing engineer subjectively assigning the distribution proportion of the unidentified leakage of system. It is beneficial to the objective evaluation of energy consumption in the thermal performance conventional test. An example shows that it is feasible.
