蒸汽质量两相流测量

A boiler operator had the quality setting at 72%. Apart from trusting the boiler manufacturer’s specifications, the only way of checking the boiler outlet quality was the traditional laborious manual method of periodically comparing the boiler inlet and outlet water sample relative salinities.

锅炉操作员将出口蒸汽的质量设定为72%。除了相信锅炉制造商的规格外，检查锅炉出口蒸汽质量的唯一方法是传统的人工方法，即定期比较锅炉进出口水样的相对盐度。

As with many industrial processes that use saturated steam flow as a thermal energy transmission method, too low a steam quality produces an inefficient process, and too high a steam quality can cause scale deposits on the pipeline. For an efficient scale free operation it is important to keep the desired steam quality. And for that an inline steam quality meter is desired.

与许多使用饱和蒸汽流作为热能传输方法的工业过程一样，太低的蒸汽质量会产生低效的过程，太高的蒸汽质量会导致管道上的水垢沉积。为了实现高效的无垢操作，保持所需的蒸汽质量是很重要的。为此，需要一个在线蒸汽质量计。

Figure 1. 4" VorTek VorCone Meter

The boiler operator installed a 4” saturated steam VorTek VorCone meter, see Figure 1. The 4”VorTek VorCone meter immediately showed a steady quality prediction of 73%, i.e. just 1% from the expected nominal 72%.

锅炉操作员安装了一个4英寸VORTEK饱和蒸汽VORCONE流量计，见图1。VorTek VorCone仪表立即稳定显示出73%的质量预测，即仅比预期的名义72%低1%。
