Flow control module and method for liquid fuel burners and liquid atomizers
An improved apparatus is disclosed for controlling the flow of liquid fuel through a feed tube onto the convex exterior surface of an atomizer bulb of the Babington type. Liquid fuel is directed through an inlet conduit into a deaeration chamber having a suitable baffle for separating entrained air and dissipating dynamic flow effects. The inlet of the feed tube for the atomizer bulb is positioned at the lower end of the deaeration chamber so that as the chamber fills with liquid fuel, any air in the feed tube is quickly flushed. Between the inlet conduit and the inlet to the feed tube, a filter plug dampens flow pulsations in the liquid passing into the inlet. The upper end of the deaeration chamber is closed and provided with an inlet to a suction conduit. An adjustment is provided to permit variation of the flow through the suction conduit and, hence, variation of the flow over the atomization bulb. To provide a constant flow rate of atomized fuel leaving the aperture even as the temperature of the fuel varies, a temperature sensitive valve may be provided at the outlet of the pump with a suitable bypass to the sump or in the suction conduit or in both locations. Methods of delivering liquid fuel are disclosed.
