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.
