<p>A process for snow melting but useful elsewhere, accomplished by an air/water interface and a water/snow interface. Water is sprayed into a stream of hot air, which is blown onto the snow. The small particles of water are intimately involved with the air molecules and the heat of the air is absorbed by the water droplets, the air giving up its heat to a very large extent. Next, the droplets are combined into larger drops, and then allowed to drop onto the snow. Water, being much heavier than air is much better at absorbing and carrying heat. The heat of the hot air is thus transferred to the snow causing it to melt by using hot water as a heat transfer medium. If the some of the water turns to steam and condenses back into water the effect is further enhanced by about ten times.</p> |
