基于灰色关联的油田锅炉节能运行综合评价
|
摘要
锅炉在油田中是主要的耗能设备,为提高其能源利用效率,对油田锅炉节能运行进行综合评价有着重要意义,传统的评价方法是将锅炉各评价指标视为同等权重下的定性分析。本文打破传统评价方法,收集某油田企业5个单位在用的68台油田锅炉运行数据,运用改进熵权法得出各评价指标权重大小,结果由大到小依次为:炉体表面温度、排烟温度、过剩空气系数、热效率、负荷率;综合运用熵权法与灰色关联分析法,计算出锅炉的关联度,判断锅炉的运行状态,定量分析油田锅炉的节能效果,对节能降耗工作具有一定的借鉴作用。
Boiler is one kind of major energy consumption equipment in oil field development.In order to increase energy utilization efficiency of boiler,it is important to make a comprehensive evaluation on energy-saving operation of boiler.Traditional evaluation method is qualitative,in which all indexes are considered to have an equal weight.Proposed is a new quantitative analysis to replace the qualitative evaluation.Based on operating data from 68 boilers operating in an oilfield,applied is the improved entropy method to obtain the weight of all evaluation indexes in a descending order:boiler body surface temperature,exhaust fume temperature,excessive air coefficient,thermal efficiency and load rate.The entropy method is combined together with the gray correlation analysis to calculate the correlation degree of boilers,showed are the operating states of each boiler and analyzed is the energy-saving effect of oilfield boilers quantitatively,which is referable for energy-saving and consumption reduction in the oilfield.
