摘要/Abstract

摘要： 锅炉热效率是评价机组运行经济性的重要指标。现有的锅炉热效率修正方法,不便于分析某因素变化对锅炉热效率的影响和运行中引起锅炉热效率降低的原因和部位。提出一种结合一阶泰勒公式并采用微分偏差修正锅炉各项损失及锅炉热效率的修正方法,并与GB 10184—88修正方法进行了比较和分析。通过对某1 025 t/h锅炉2个不同试验工况下锅炉各项损失及锅炉热效率的计算,表明微分偏差修正法修正后的各项损失及锅炉热效率与GB 10184—88修正后的数值差别较小,可以应用于工程实际。

Abstract: Boiler thermal efficiency is an important indicator to evaluate the economic efficiency of thermal power unit in operation. When a parameter changes, the existing correction method of boiler thermal efficiency is inconvenient to analyze its influence to the boiler thermal efficiency, and it is also inconvenient to analyze the reason and location which cause the reduction of the boiler thermal efficiency in operation. A new correction method which combined differential deviation method with first order Taylor formula was proposed to revise the various losses and boiler thermal efficiency, and comparison and analysis of correction calculation method were also conducted between the innovative correction method and the Chinese Utility Boiler Performance Test Code GB 10184—88. Taking a 1025 t/h boiler for example, various losses and boiler thermal efficiency were calculated under two different test conditions, The results show that the difference of the losses and boiler thermal efficiency calculated on differential modification method and GB 10184—88 codes is tiny after modification, so this method can be applied into the engineering practice.

Key words: boiler thermal efficiency, correction calculation, GB 10184—88 codes, economic diagnosis
