摘要

提出了一种利用混沌优化算法分析入炉煤元素和低位发热量的实时软测量技术

该技术可通过实时采集主机、磨煤机、空气预热器等设备的运行参数

在线计算得到入炉煤元素成分和低位发热量

该方法对煤质初始值的选择无依赖性

适合工程应用。采用该技术计算得到的结果不仅可以用于锅炉优化运行

而且可以用于计算发、供电煤耗

以供节能调度、煤场管理等系统使用。

Abstract

A real-time soft-sensing technique using chaos optimization algorithm to analyze element contents and net calorific value of burning coal in utility boilers was proposed.On the basis of collecting real time operation parameters of boiler

turbine

mill

air preheater and other devices

this technology can online calculate the chemical composition and low heating value of the coal.Moreover

this calculation method has no dependence on selection of coal quality's initial value

which is suitable to engineering application.The results can be used to optimize the boiler operation

or to calculate the power consumption for the energy saving scheduling system and coal pit management system.
