In glass manufacturing, traditionally under port firing systems are utilized in end fired furnaces. Such set-ups provide operational flexibility in terms of adjusting combustion conditions to meet fuel consumption and NOx emission targets. Furnace designs incorporating underport firing systems have been investigated extensively by in-situ measurements and numerical simulations. Adapting the knowhow on designing and operating the underport firing systems to side fired float furnaces that are commonly equipped with side through port systems appear to be promising to develop energy efficient and low emission furnace designs. Accordingly, in recent years there is a rise in number of float furnaces commissioned that utilize under port firing systems, however, only a very limited number of detailed investigations of such systems has been reported.
In this paper, it is aimed to evaluate the performance of under port firing system in side fired float furnaces. Firstly, numerical simulations are carried out for a traditional float furnace with a pull rate of 725 tons per day to obtain optimum conditions for fuel consumption and NOx emissions. Then, the same case is examined for the similar furnace with an underport firing system. Effects of burner angle and burner height are also studied within this framework. It has been seen that similar energy efficiency results could be obtained with the optimized cases. Detailed results of the study will be presented in the paper.
