Abstract
A low pressure atomizer is used for the atomization of liquids, such as atomization of fuels found in industrial burners. An atomizer body has an atomizing chamber therein and an annular liquid conduit having an annular diffusion member therein. The diffusion member is shaped to direct liquid passing thereby and into the atomizing chamber and forces the liquid to enter the chamber adjacent the walls thereof. The atomizer body has a first annular gas conduit and a tangential gas port connected between the annular gas conduit and the liquid conduit so that the gas impinges tangentially against the liquid to shear and rotate the liquid entering the atomization chamber. A second annular gas conduit has an angled open into the atomizing chamber to further shear the liquid and gas mixture in the atomizer chamber so that a low pressure atomizer atomizes a liquid with low pressure gas streams. A plurality of tangential gas ports connect the gas conduit to the atomizing chamber with the tangential ports being generally perpendicular to the gas conduit.
