title = "Observer-Based Fuel Control Using Oxygen Measurement",
abstract = "This report describes an attempt to improve the existing control af coal mills used at the Danish power plant Nordjyllandsv{\ae}rket Unit 3. The coal mills are not equipped with coal flow sensors; thus an observer-based approach is investigated. A nonlinear differential equation model of the boiler is constructed and validated against data obtained at the plant. A Kalman filter based on measurements of combustion air flow led into the furnace and oxygen concentration in the flue gas is designed to estimate the actual coal flow. With this estimate, it becomes possible to close an inner loop around the coal mill itself.",
