Abstract:
A method of removing gas from a liquid, the method comprising:providing: a bubble capture chamber, an exhaust manifold, and a tapered extraction chamber extending from the bubble capture chamber towards the exhaust manifold, the tapered extraction chamber having walls that taper outwards with increasing distance from the bubble capture chamber; accumulating a bubble of gas in the bubble capture chamber; heating a portion of the liquid in the tapered extraction chamber to nucleate a bubble of vapor; heating the bubble of vapor to explosively expand the bubble of vapor into contact with the walls of the tapered extraction chamber and into contact with the bubble of gas to form a composite bubble, contact with the walls of the tapered extraction moving the composite bubble towards the exhaust manifold; and discontinuing heating of the composite bubble to condense the vapor in the composite bubble.
