LNG浸没燃烧式气化器结构及运行特性数值模拟
Numerical simulation of the structure and operating characteristics of the LNG submerged combustion vaporizer
摘要
Abstract
Objective The submerged combustion vaporizer(SCV)is the core heat transfer equipment in the liquefied natural gas(LNG)industry chain.By optimizing performance configuration and operating parameters of SCV,its operating characteristics are studied.Method By using means of numerical simulation,this paper systematically compared the six configurations including systematic/staggered arrangement serpentine tubes and single-hole/double-hole/three-hole flue gas distributors,and studied the impact rule on heat transfer characteristics of inlet parameters of LNG in a staggered arrangement double-hole configuration and fuel gas parameter.Result It was found that the SCV with a staggered arrangement double-hole configuration had the best heat transfer performance.The results showed that the overall heat transfer performance of SCV increased with the increase of LNG inlet flow rate,LNG inlet pressure,flue gas apparent velocity and double-hole flue gas inlet temperature.Conclusion The gas-liquid two phase heat transfer process of SCV can be effectively improved by changing the serpentine tube and flue gas distribution outlet configurations.The research results may provide dual references for the optimal structures and reasonable operating control of domesticating SCV.关键词
