热水天然气换热器是保证燃机天然气入口温度的重要设备,该设备长期依赖进口。为保证项目的使用要求,大连派思燃气系统有限公司根据GE规范自主开发设计制造了热水天然气换热器,实现了国产化。但投入运行后发现,该热水天然气换热器的水侧出口的回水温度偏高。因此必须对换热器的结构进行改进。
Hot water natural gas heat exchanger is to ensure that gas turbine inlet gas temperature important equipment, the device has long been dependent on imports. To ensure the use of the project requirements, Dalian Paisi Gas Systems Co., Ltd. independently developed according to GE specifications design and manufacture of hot water natural gas heat exchanger, to achieve the localization. However, after putting it into operation, it was found that the return water temperature at the water side outlet of the hot natural gas heat exchanger is high. Therefore, the structure of the heat exchanger must be improved.
