Glass furnace technology for reduced emissions based on advanced control and monitoring

Abstract

This paper reports an advanced furnace viewing sensor for regenerative U-flamed glass furnaces, which is demonstrated in a 40 t /d pull furnace of tableware glass burning thick fuel oil. The system processes digitized images from the combustion Chamber a n d uses information related to the geometric features of the flame for monitoring furnace Performance. The procedure is shown t o be able to reduce NOₓ, levels by u p to 20 %, by means of adequate control of the fuel atomization air.
