HEAT EXCHANGER FOR REMOVAL OF CONDENSATE FROM A STEAM DISPERSION SYSTEM

摘要

A steam dispersion apparatus includes a steam chamber communicating in an open-loop arrangement with a first steam source for supplying steam to the steam chamber. The steam chamber includes a steam dispersion location at which steam exits therefrom at generally atmospheric pressure. A heat exchanger communicates in a closed-loop arrangement with a second steam source for supplying steam to the heat exchanger at a pressure generally higher than atmospheric pressure. The heat exchanger is located at a location that is not directly exposed to the air to be humidified, the heat exchanger being in fluid communication with the steam chamber so as to contact condensate from the steam chamber. The heat exchanger converts condensate formed by the steam chamber back to steam when the condensate contacts the heat exchanger.

1. A steam dispersion system comprising:
a header having a header interior; a plurality of steam dispersion tubes for dispersing steam into air desired to be humidified, the steam dispersion tubes extending upwardly from a top side of the header and having tube interiors in fluid communication with the header interior; a heat exchanger positioned within the header interior that supplies heat for evaporating condensate within the header interior; and a piping arrangement that supplies steam having a first pressure to an interior of the heat exchanger and supplies steam having a second pressure to the header interior, the first pressure being higher than the second pressure.
