| 内容記述 | The moisture droplets entrained by steam from a boiler steam drum bring some trouble or damage to instruments and machines which are driven by steam. To avoid them, it is necessary to raise steam purity. To find the definite effects of evaporating steam velocity and vertical distance between water surface and a sampling port on steam purity, experiments were carried out on four different stages of steam velocity and on seven different stages of vertical distance respectively. Results are shown as follows. Steam velocity and vertical distance, relating to each other, have some influences on steam purity. Increase of vertical distance makes gravity separation effective and the effect becomes remarkable as steam velocity increases. With increase of steam velocity, the swelling caused by void becomes higher, surface waves become violent and lift force to the moisture droplets increases and mean diameter of the entrained droplets becomes large. As a result, at a low zone of the vertical distance steam purity decreases because many large droplets arrive, but at an adequate high zone of it gravity separation is accomplished effectively because the droplets become heavy, and it has a good effect on steam purification. However, if vertical distance increases too much and passing area for the steam decreases, steam velocity is increased and accordingly lift force to the droplets is increased. Consequently the effect of gravity separation on small droplets will be minimized. | |||||
