Sensor arrangement for spatial delimitation of the atmospheres in continuously operated industrial furnaces

摘要

The invention relates to a sensor arrangement for spatial delimitation of the atmospheres in continuously operated industrial furnaces, preferably in tunnel furnaces or continuous furnaces in the ceramics industry. The technical aim of the invention consists in developing a sensor arrangement for spatial delimitation of the atmospheres in continuously operated industrial furnaces which guarantees, irrespective of the changes in the atmospheres caused in terms of flow by the combustion and the car charge, a spatial delimitation, necessary for process management which is suitable for the quality, between oxidising and reducing atmospheres while observing the necessary process parameters, by selectively influencing the supply of the oxygen-containing carrier gas. According to the invention, the technical aim is achieved by known solids sensors being arranged in two cross-sections which spatially delimit the transition region between oxidising and reducing atmospheres. The cross-sections are in this case preferably arranged in the region of the burning zone.
