RAPID ABSORPTION STEAM HUMIDIFYING SYSTEM

摘要

An improved apparatus for introducing steam into an airstream in a heating, ventilating and air conditioning 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 is forced into the return header under the influence of steam pressure and gravity. Both headers may further be inclined to improve drainage of condensation. The invention optionally may utilize fenders in conjunction with the steam dispersing structure to minimize heat transfer to the airstream.
