摘　　要：介绍了玻璃纤维窑炉空气助燃火焰空间三维数学模型的建立,其中气相流动模型由标准k-ε湍流模型组成,化学反应模型使用有限速率/涡耗散模型,辐射传热模型使用离散坐标模型。以某玻纤厂年产2,万,t玻璃纤维的熔窑为研究对象,用CFD软件模拟燃烧空间内气体的流动、温度分布和压力分布状况。通过模拟结果与现场实测数据进行比较,该数学模型能够比较客观地反映单元玻璃窑炉富氧燃烧空间的温度场、速度场和压力场的分布规律。A three-dimensional mathematical model of the combustion space of air-fuel fiberglass furnace was established,which consisted of a gas flow model in form of standard k-ε model,a chemical reaction model in form of eddy-dissipation model and a radiation model in form of discrete ordinates model.With a 20000 t/y fiberglass furnace as the studying object,the gas flow and the distribution of temperature and pressure fields in the combustion space were simulated using CFD software.By comparing the simulation results and the on-site measurements,it can be suggested that the mathematical model can objectively reflect the real distribution of the temperature field,velocity field and pressure field of the unit melter for producing glass fiber.
