水作为工质和载体进入发电厂,经过一系列的用水过程最后损失一部分并被排放掉。它作为工质吸收燃料的热量,然后由发电机变为电能输出。在发电的其他环节也离不开水,各转动设备和凝汽器的冷却用水,作为载体的锅炉排灰用水,以及绿化用水,生活区的用水等。以上各种用途的水会有不同的水质要求,经过不同的途径使用后,常会混入各种杂质使水质发生变化,形成电厂复杂的用水系统。本论文主要研究分析了火力发电行业用水特点、定额编制原则、方法及取水定额确定。
Water enters the power plant as a working fluid and carrier and eventually loses part of it through a series of water processes and is discharged. It absorbs the heat of the fuel as a working fluid and is then converted by the generator into electrical energy. Other aspects of power generation are inseparable from the water, the cooling water of the rotating equipment and the condenser, the boiler ash discharge water as a carrier, the greening water and the water of the living area. The above various uses of water will have different water quality requirements, after different ways to use, often mixed with various impurities to make the water quality changes, the formation of complex power plant water system. This paper mainly studies and analyzes the characteristics of thermal power industry water use, the principle and method of quota establishment and water quota determination.
