An improved apparatus and method for delivering liquid are disclosed for use in fuel burners or atomizers of the type which comprise a hollow atomizer bulb having a convex exterior surface which tapers toward a small aperture through which high pressure gas if forced to atomize liquid as it flows in a thin film over the bulb. To provide thinner films when lower atomization rates are desired and thicker films when higher atomization rates are desired, a feed tube is positioned above the atomizer bulb with its discharge opening oriented so that the vertical distance from its front edge to the surface of the bulb is from 1.5 to 2.0 times the vertical distance of its rear edge to the surface of the bulb. In another embodiment the discharge opening of the feed tube is elongated and has a major axis oriented transversely to the axis of the spray leaving the aperture.
