Abstract: To localize the core design and manufacturing technologies of LNG large - scale ORV and solve the existing technological problems, heat transfer mechanism of high-effective LNG heat-exchanging tube was brought under numerical simulation. LNG large-scale ORV was localized on the basis of research and development of the key manufacturing technology. The equipment was satisfactory for industrial application. The operational results indicated that sea water distribution formed a uniform and stable film on the tube surface. The surface coating of the gasifier has a high-strength combination without any coating coming off. ORV gasification capacity satisfies the process requirements with all the data reaching the standards. The equipment is in stable operation. No leakage, distortion or vibration took place in the operational process. Industrial operation of LNG ORV is in line with the relative technological requirements.
