海水开架式气化器（Open Rack Vaporizer，ORV）和浸没燃烧式气化器（Submerged Combustion Vaporizer，SCV）是LNG接收站LNG气化的重要设备。ORV运行成本远低于SCV，但在冬季海水入口温度较低时，ORV操作负荷受到限制。对海水入口温度2～6 ℃时ORV的运行情况进行测试，提出了ORV达到最大操作负荷的判定标准。通过Origin软件对海水入口温度、海水出口温度、LNG流量运行数据进行拟合，得到了ORV最大允许LNG流量函数式，可以较精确地计算不同海水入口温度下ORV能够处理的最大LNG流量。利用该函数式，结合某LNG接收站2015-2016年冬季外输量，得出了ORV和SCV运行模式优化方案。通过最大程度利用ORV进行气化外输， LNG接收站冬季气化成本节约达到1 070×104元。
