油舱蒸汽加热的计算与对比

Calculation and comparison of steam heating for oil tank

    摘要
  • 摘要:
      目的  为了设计和优化油舱的蒸汽加热系统，对油舱的蒸汽加热过程进行计算，
      方法  采用Flowmaster仿真计算方法与传统计算方法进行计算，并将计算结果进行对比分析，确认其计算结果的可信性。采用2种方法，分别考察环境温度、加热盘管长度、蒸汽流量、蒸汽温度及加热盘管传热系数对加热过程的影响。
      结果  计算结果表明，2种方法的计算误差在3%~7%左右，且通过计算发现，油舱蒸汽加热系统存在最优的加热盘管长度和蒸汽流量等设计参数。2种方法各有其长短，其中仿真计算适用于优化设计，而传统方法便于初步估算。采用2种方法结合的设计方法，可互补长短。
      结论  研究结果对油舱蒸汽加热系统的设计具有一定的参考价值。

     

    Abstract:
      Objectives   For the optimization of an oil tank steam heating system,
      Methods   the author used the Flowmaster simulation calculation method and tradition calculation method and made comparative analysis on the calculation results to verify the dependability of the calculation results. Two methods were used to examine how ambient temperature, heating coil pipe length, steam flow rate, steam temperature and heating coil pipe HTC(heat transfer coefficient) could affect the heating process.
      Results   the calculation results indicate that calculation error margin of the two methods is about 3%~7% and there are design parameters such as a heating coil pipe length and a steam flow rate in the design of the oil tank steam heating system. Both methods have advantages and disadvantages, where simulation calculation is suitable for optimization design while traditional calculation is favorable for preliminary estimation. Combination of the two methods can offset their disadvantages.
      Conclusions   The study result can be used as reference for design of oil tank steam heating system.
