'ac*roun (cont+) Prob,em escription 

The existing &easure&ent point ,at the 'ridge 3all leads to i&precise reading" This forces operating the furnaces at higher excess oxygen to ensure co&plete co&'ustion at the expense of ther&al efficiency"

The proposed &odification is to opti&i)e the co&'ustion via installation of Tuna'le iode Laser Spectroscopy ,TLS analy)ers in all !*2 and !*+ furnaces as per the follo3ing setup#
