Abstract

Abstract:

In the process of oil and gas field production, as well as in the gathering and transportation phases, the water jacket furnace coil serves as a crucial component for natural gas heating, playing a significant role in both heating and energy support. However, the presence of fine grit within the water jacket furnace coils can result in erosion damage that is challenging to predict. Therefore, it is essential to understand the factors influencing the erosion of water jacket furnace coils and to establish an effective predictive model. This study employs computational fluid dynamics (CFD) simulations and sensitivity analyses to investigate the effects of temperature, pressure, gas flow rate, particle diameter, bend diameter, and curvature radius on the erosion of water jacket furnace coils. The results indicate that the gas flow rate, particle diameter, bend diameter, and curvature radius are the primary factors affecting erosion. Consequently, a comprehensive erosion prediction model is developed, providing a scientific basis for equipment maintenance and safety management. The findings of this study offer a vital reference for addressing the erosion issues associated with water jacket furnace coils and hold practical significance in engineering applications.

摘要：

在油气田生产和集输过程中，水套炉盘管作为天然气加热系统的关键设备，承担着重要的热能供应与保障作用。然而，水套炉盘管内部的细小颗粒易引发冲蚀损伤，且该过程难以提前预测。因此，了解影响水套炉盘管冲蚀的因素并建立有效的预测模型至关重要。采用计算流体动力学（CFD）数值模拟并结合敏感性分析方法，研究了温度、压力、气体流速、颗粒直径、弯管直径和曲率半径等因素对水套炉盘管冲蚀的影响。结果表明，气体流速、颗粒直径、弯管直径和曲率半径是影响冲蚀的主要因素。建立的综合冲蚀预测模型，为水套炉盘管的维护和安全管理提供了科学依据，具有工程实践意义。
