Co-generation of Electricity and Desalted Water by Gas Turbine MHTGR

摘要

The shortage of water resources and their imbalanced distribution have become one of the main bottleneck problems which inhibit China's sustainable development. Seawater desalination will be an effective measure to alleviate the shortage of water resource in coastal areas. Mass production of desalted water needs cheep energy. Nuclear energy may be a good selection for this purpose. The gas turbine Modular High Temperature Gas-cooled Reactor (MHTGR) system can be coupled with the seawater desalination system without affecting the electrical generation. The removal heat can be used to produce desalted water because its thermal parameters can meet the requirement for the low-temperature multi-effect distillation (LT-MED) of seawater desalination. The co-generation of electricity and seawater desalination by gas turbine MHTGR is an economical and feasible technique to alleviate the shortage of energy and water supply. This combined cycle can provide an effective technical support for China's sustainable development.
