摘要
采用双方程湍流模型、概率密度函数(PDF)燃烧模型和离散坐标(DO)辐射模型,对采用高温空气燃烧技术的燃气热态试验炉炉内工况进行了非稳态数值模拟,预测热态试验炉运行时的炉内温度场、组分场和速度场,由数值模拟结果分析比较了不同喷口间距五喷口燃烧器对炉内工况的影响,为采用高温空气燃烧技术的燃气燃烧器设计提供参考。
By utilizing the k-ε turbulent equation model, probability density function (PDF) and discrete ordinate(DO) model, the unsteady combustion process in the gas-fired furnace using the HTAC technology is numerical simulated. The temperature, species and velocity distributions are predicted. The influence of the five-nozzle burns with different space length between central and surrounding nozzles on the process in the furnace is compared and analyzed. Thus provide some reference in the gas-fired HTAC burner designing.
