The invention discloses an FSRU regasification device multiple heating system which comprises a liquefied natural gas storage bin, a buffer tank, an evaporator, a steam/ethylene glycol heat exchanger, a closed heating system, a waste heat recovery heating system, a central cooling water heating system, an open seawater heating system and an air heating system. The waste heat recovery heating system and the central cooling water heating system make full use of waste gas and waste heat of a generator on the ship and heat dissipation of mechanical equipment, the use efficiency of energy in the ship is remarkably improved, fuel is saved, pollutant emission is reduced, meanwhile, the air heating system can be alternately used with the open type seawater system along with seasonal changes, and the energy-saving and environment-friendly effects are achieved. Regasification heating is completed through the air heating system, the pollution influence on the marine environment is avoided, a proper heating mode can be selected according to different factors such as different places of actual projects, local environments (seawater, air temperature and the like), local laws and regulations, output capacity and the like, and the flexibility of project operation is improved.
本发明公开了一种FSRU再气化装置多重加热系统,包括液化天然气储存仓、缓冲罐、蒸发器、蒸汽/乙二醇换热器、闭式加热系统、废热回收加热系统、中央冷却水加热系统、开式海水加热系统以及空气加热系统,本发明通过废热回收加热系统和中央冷却水加热系统充分利用船上发电机废气废热和机械设备散热,显著提高了船舶内部能源的使用效率,节约燃料使用,降低污染排放,同时空气加热系统也能随着季节变化和开式海水系统交替使用,通过空气加热系统完成再气化加热,避免对海洋环境的污染影响,本发明可根据实际项目所在地不同、当地环境(海水、气温等)、当地法规和外输能力等不同因素选择合适的加热模式,提升项目运行的灵活性。
