Abstract:
A container of water is subject to reduced air pressure to induce an inflow of air through conduits extending from the exterior of the container to a point below the level of the water in the container. Air entering through these conduits bubbles up through the water. The size of the bubbles is controlled by the ports at which the air moving in the conduits enters the water. The blower providing the reduced pressure delivers the moisture-ladened air from the bubbles to the intake of another blower providing combustion air for a burner installation. The minute quantities of vapor-ladened air are mixed in that blower, or in the blower intake chamber, with the remainder of the incoming combustion air. The supply of vapor is related to the firing rate in the burner by associating the burner control with the off-on condition of a valve in at least one of a plurality of air conduits of the container.
