LNG气化器是LNG接收站中除LNG储罐外单体投资最大、最重要的设备，对项目的安全生产起到关键作用，长期受制于国外公司，开展国内自主化成为当务之急。以大型LNG气化器为例，总结LNG装备自主化的技术路线与研究经验，为后续LNG设备或其他行业设备自主化项目提供参考。

LNG vaporizer is the second most important equipment with the second largest investment in LNG terminal,only next to LNG storage tank.It plays a key role in the safety production.The manufacture technology for LNG vaporizer has been subjected to foreign companies for a long time and it is necessary to develop China's independent technology.Taking large LNG vaporizer as example,this paper summarizes China's technical routines and research experiences for independent development of LNG equipment,and also provides references for China's independent development projects of subsequent LNG equipment or other industrial equipment.
