In this paper, Monte-Carlo Method is used for the calculation of heat transfer in the radiation chamber of a crude oil cylindrical tubular heater with multiple burners. Soave model is used for the calculation of phase equilibrium of the crude oil containing water flowing tnrough the radiation tubes. The flow of combustion gas in the radiation chamber is assumed to be piston type. The calculation results are compared with operation data. The relative errors are as follows: effective heat capacity of the radiation chamber 2.1%, average heat flux of the radiation tubes 7.5%, flow gas temperature at the top of the chamber 7.8%, evaporation fraction of the crude oil 14.8%, and the inlet pressure of crude oil 25%.

由于炼油厂的圆筒炉一般都是多火嘴的,所以我们在对单火咀圆筒炉的传热进行研究的基础上,又对多火嘴圆筒炉炉膛的温度、热强度分布及管内压降进行了进一步的探讨和计算。辐射部分仍然采用Monte—Carlo法、三维柱坐标系进行计算,对流部分则改用元体平衡法进行计算。烟气流动仍近似假设为活塞流。
