METHOD AND MEANS FOR MEASURING THE OXYGEN CONTENT OF FLUE GAS IN A BOILER

摘要

The oxygen content in a flue gas generated in a furnace of a boiler having pressurized areas and employed for controlling the air/fuel ratio at burners of the furnace as a function of the measured flue gas oxygen content is measured. This measurement is carried out by at least one high-temperature oxygen-measuring probe located within the furnace itself and/or adjacent a furnace outlet of the furnace.
