Rapid absorption steam humidifying system

摘要

An improved apparatus for introducing steam into an airstream in an HVAC system includes a supply header, steam dispersing structure and structure for collecting condensation from the steam dispersing structure. The supply header is adapted for connection to a source of steam and is preferably elevated with respect to the return header, so that condensation in the supply header and steam dispersing structure is forced into the return header under the influence of steam pressure and gravity. One embodiment of the invention presents a pair of streamlined jackets on one or more of the dispersion tubes that reduce heat loss to the air stream, thereby reducing the amount of condensate that is formed. The jackets are streamlined to minimize turbulence and static pressure loss.
