Study on power generation performance of sea water evaporation steam

Seawater with softening pretreatment was used as the medium for experiment evaporation, and the influence of influent water, influent water temperature and flue gas flow on the steam flow and evaporation rate is discussed in this paper. The results show that with the increase of water inflow, the evaporation rate decreases at the beginning and then increases. Steam flow increases with the increasing water inflow; the increase of influent temperature has great influence on the evaporation rate and steam flow, however, the evaporation rate hardly changes when the influent temperature reaches a certain value; Steam flow and evaporation rate increases with increasing flue gas flow, and increases slightly with increasing before reaching 90m³/h. The surface of the heating tube was analyzed by means of SEM and X-ray diffraction. These discussions and results has some guiding significance in designing evaporation equipment using softening pretreatment. (paper)
