Problems solved by technology
[0002] The natural gas gasification skid is usually equipped with an electric heating liquid natural gas (LNG) vaporizer and a gaseous natural gas (BOG) heat exchanger respectively. Placing two electric heating heat exchange equipment on one gasification skid not only increases the area of the gasification skid, At the same time, the floor area of the station building is increased, and two electric heaters are used, which not only consumes a lot of power, but also increases the operating cost

Description
(1) Technical field [0001] The invention relates to gasification application equipment for a natural gas station, in particular to a natural gas gasification heat exchanger for single-coil dual-use electric heating. (2) Background technology [0002] The natural gas gasification skid is usually equipped with an electric heating liquid natural gas (LNG) vaporizer and a gaseous natural gas (BOG) heat exchanger respectively. Placing two electric heating heat exchange equipment on one gasification skid not only increases the area of the gasification skid, At the same time, the floor area of the station building is increased, and two electric heaters are used, which not only consumes a lot of power, but also increases the operating cost. (3) Contents of the invention [0003] The object of the present invention is to solve the above existing problems and provide a single-coil dual-use electric heating natural gas gasification heat exchanger. In the case of using an electri...
