According to the characteristics of spray combustion in the oil-burned boiler equipped with Venrnturi Burner and based on the simulation results of internal and external aerodynamic field under cold condirntion and gas-phase combustion field employed EBU model, the numerical simulation of the gas-liquid twornphase flow and combustion in the outlet of venturi burner are presented. Distributions of pressure, velocity, rntemperature and ingredient concentration in chamber are provided. By theoretical analysis and contrast with rnthe experimental results about Venturi Burner, the models, numerical methods and the numerical results rngiven in this paper are credible. The numerical results can be used to guide the further design and operation rnof this type oil-burned boiler.%针对选配文丘利型油燃烧器的燃油锅炉中液雾燃烧的特点，在冷态等温流场数值模拟结果及rnEBU-Arrhenius模型模拟气相燃烧所得结果的基础上，数值模拟了单只文丘利油燃烧器出口的气液两相rn流动与燃烧，给出了流场中的速度场、温度场以及浓度场的分布信息，这些结论可为该型燃油锅炉的进rn一步设计和运行以及燃烧室的布置提供有益的依据。
