System for optimizing oxygen in a boiler

摘要

A method and apparatus for controlling a parameter associated with operation of a fossil fuel fired power generating unit. An optimizer determines optimal setpoint values for manipulated variables used to operate the power generating unit by accessing a model that predicts a parameter sensed by a plurality of sensors. The optimizer uses the model to minimize a cost valve of a cost function while observing at least one constraint associated with operation of the power generating unit.
