海洋热能转换

海洋热能转换是一种将热能转化为电能的技术。最适合用于海洋表层水温较高的热带和亚热带地区。该技术的一个特点是能够全天候进行稳定的电力供应。因此,它非常适合满足基本负载需求。


此外,用于发电的深海水可以用于二次应用,可以促进当地工业和偏远岛屿社区的地方经济。

OTEC process

OTEC系统由蒸发器、冷凝器、涡轮机、发电机和泵等部件组成。该系统利用温暖表层海水和深层海水(取自深度6001000米)之间的温差来发电。具有低沸点的工作流体吸收蒸发器中温暖表层海水的热量而蒸发,蒸汽驱动涡轮机,涡轮机又驱动发电机发电。然后蒸汽通过冷凝器,将热能转移到寒冷的海水中,使蒸汽还原为液态。

为了最大限度地提高该过程中每个部分的效率,从进水到热交换、发电和排水,该系统依赖于集成的控制和监测系统、性能管理软件、安全仪表、无线通信和各种传感器。优化整个系统会使运行稳定并提高发电效率。

概述:

Okinawa Prefecture is promoting clean energy with the aim of becoming a low-carbon society in the 21st century. Ocean thermal energy conversion (OTEC) technology is particularly well suited for this purpose, and is expected to both reduce the environmental impact that power generation has in the prefecture and lessen the prefecture's dependence on imported fossil fuels.

概述:

Facing serious environmental problems for the whole earth, clean energy using solar, wind, geothermal, tidal, etc... to reduce CO2 emissions is an inevitable matter. Renewable energy providers need economical/reliable/efficient solutions. Yokogawa provides a reliable data acquisition system with high accuracy for measurement and control instruments.
