To improve boiler ' s reliability and economy performance , this paper based on the studies of present utility boiler operation and management was mainly focused on the following several aspects : 1 . build up efficiency calculation model and discuss the method to optimize the boiler performance for the purpose of raising accuracy of efficiency analysis 本文根据对国内外电站锅炉运行、管理的现状及其现有问题的研究,在提高锅炉运行可靠性和经济性方面做了以下工作: ( 1 )建立锅炉效率计算的数学模型,研究热效率的计算方法,提高其分析的准确性。
It is concluded that the categories of sootblowing income and cost on different heating surface are not all the same . the method to calculate accurately the income and cost is studied . the magnitude of all income and cost categories is calculated and compared by calculating the boiler performance change with the clean factor 研究每种成本和收益的精确计算方法,并以北仑发电厂1 #锅炉为研究对象,通过计算清洁因子对锅炉性能的影响,以统一标准比较各种吹灰收益和成本的大小。
And the law gained from differential calculus is coincident well with the calculated result . grounded upon the research on the sootblower operation , the effect on all kinds of boiler performance of ash fouling on heating surface is analyzed roundly . and the sootblowing income is divided into five categories 在现有吹灰器研究和运行水平的基础上,全面分析电站锅炉各部位受热面灰污对锅炉各方面性能的影响,将电站锅炉吹灰的收益和成本各归纳为五类,得出不同受热面吹灰的收益和成本不尽相同的结论。
