Numerical simulation of combustion space in oxygen-fuel fiberglass furnace

This paper establishes a three-dimensional mathematical model of glass furnace combustion space, according to the practical situation of a fiberglass furnace whose production is up to 20,000 ton per year by use of Fluent, analyzes the defects in the combustion space, and improves the furnace structure. The results show that the relative average error between measurement data and simulation value on crown is 8.70% and on glass-molten surface is 2.32%; the flow field distribution is not uniform in the place of guns 3, 4 which cause the large thermal load; after improvement, it can keep the reasonable temperature field, reduce the thermal load on crown and improve the flow field distribution.
