SYSTEMS AND METHODS FOR CONTROLLING NON-CONDENSABLE GASES

摘要

Methods and systems for diffusing non-condensable gas are described. In an embodiment, a gas diffusion apparatus may be used to reduce non-condensable gas located adjacent to a condensation surface of a heat transfer system. The non-condensable gas may impede condensation at the condensation surface. The gas diffusion apparatus may include a plurality of blades arranged around a hub that is perpendicular to the condensation surface. The plurality of blades may rotate in a plane that is parallel or substantially parallel to the condensation surface. As the blades rotate, they generate gas flow that moves the non-condensable gas away from the condensation surface and imparts momentum on the vapor molecules heading toward the condensation surface. The blades may also contact the non-condensable gas layer and push them away from the condensation surface.

1. A vapor condensation system comprising:
a condensation surface configured to facilitate condensation of vapor thereon; and a gas diffusion apparatus comprising a plurality of blades configured to rotate in a plane that is perpendicular to a hub, the gas diffusion apparatus being arranged such that the hub is perpendicular to the condensation surface, wherein rotation of the plurality of blades is configured to promote condensation of vapor on the condensation surface by reducing an amount of non-condensable gas located adjacent to the condensation surface that impedes condensation of the vapor.
