摘要

针对某电厂两台燃煤机组煤耗数据偏差较大问题

对两台机组发电、供电煤耗进行对比评估。通过查验机组运行参数、入炉煤煤质数据、灰渣可燃物、掺配方案、机组指标统计表等数据

基于能耗指标数据

采用耗差法对煤耗影响因素进行分析

同时采用正平衡修正法对供电煤耗数据进行分析和修正计算

最后得出相关结论。

Abstract

In view of the large deviation of the coal consumption data between two coal-fired units in a power plant

coal consumption of the two coal-fired units is compared and evaluated. Through checking the relevant historical data such as operating parameters of the units

data of fired coal properties

ash and slag combustibles

blending schemes

units’ index statistical tables

etc.

consumption difference method is used to investigate the factors which impact coal consumption based on energy consumption index data. At the same time

positive balance revised method is used to analyze and correct the coal consumption data. At last the relevant conclusions are drawn.
