Abstract
A CO controller is used in a boiler (e.g. those that are used in power generation), which has a theoretical maximum thermal efficiency when the combustion is exactly stoichiometric. The objective is to control excess oxygen (XSO2) so that the CO will be continually on the “knee” of the CO vs. XSO2 curve.
