Recovering Steam Clouds and Waste Heat | TLV - A Steam

When used in heating processes, steam loses its latent heat energy and condenses. The resultant condensate is usually over 100°C [212°F], and may contain as much as 30% of the heat energy originally held by steam. When flash steam from condensate is vented to atmosphere, this valuable heat energy, much of which can be recoverable, goes to waste.

A heat pump is a device that can increase the temperature of a waste-heat source to a temperature where the waste heat becomes useful. The waste heat can then replace purchased energy and reduce energy costs. However, the increase in temperature is not achieved without cost. A heat pump requires an external mechanical- or thermal-energy source.
