卧式氨储罐储氨量计算

The ammonia storage content calculation of horizontal liquid ammonia tank

为准确计算燃煤电厂卧式氨储罐的储氨量,通过分析氨的气-液两相转化规律、氨储罐内气相压力变化规律以及液态氨密度变化规律,提出了通过氨储罐内温度、压力和液氨液位来计算氨储量的方法。现场应用表明,该方法能较准确地计算出氨储罐的储氨量、一段时间内的氨消耗量以及卸氨量等。

In order to accurately calculate the ammonia storage content of horizontal liquid ammonia tank,this paper analyzed the gas-liquid transformation rule of ammonia and the changing rules of gas phase pressure and liquid ammonia density in liquid ammonia tank,and proposed a calculation method of ammonia storage content according to the temperature,pressure and liquid ammonia level in liquid ammonia tank. The field application indicated that this method could accurately calculate the ammonia storage content of liquid ammonia tank,the consumption and unloading capacity of ammonia over a period of time,etc.
