摘要
长期以来 ,锅炉运行经济性的评价是以设计值、运行经验值或统计值作为基准值 ,这些值往往不一致 ,而本文是用变工况热力计算确定运行参数基准值来对锅炉进行经济性评价的。同时 ,本文提出在准确计算基准值的基础上 ,通过对电站锅炉运行经济性指标的偏差分析来确定各经济性指标的变化对热损失和锅炉效率的影响程度。
For a long time,while judging the economy of the boiler operation,the design value,the operation value or the statistical value is regard as the datum.Because these values are not conformity,in this paper,the operation parameter datum is determined by the thermal calculation under different loads,then evaluate the boiler operation economy.At the same time,on the basis of calculating the datum accurately,by the analysis of the thermal deviation of the boiler operation economic thermal marks,it has been determined how the changes of economy marks effect the thermal loss and the boiler efficiency.
