The gas bubble generator is submerged within a large body of liquid and is attached to a stackpipe. The gas bubble generator comprises a first gas accumulation chamber, a second gas accumulation chamber and a stand pipe having a gas outlet through which gas exits the bubble generator. The gas bubble generator furth er comprises a continuous passageway between the second gas accumulation chambe r and the stand pipe through which gas can travel from the first and second ga s accumulation chambers to the gas outlet. The continuous passageway is absent a hydraulic braking orifice.</p> |
