FUEL INJECTOR FOR A LIQUID FUEL BURNER

摘要

A fuel injector for a liquid fuel burner that provides for large turn-down ratios and low firing rates. The fuel injector has a fast acting valve to provide a pulsed flow of fuel from a fuel supply and a nozzle coupled to the valve for receiving and atomizing the pulsed flow of fuel. The pulse of atomizing fuel is injected into the throat of a burner. A fuel controller coupled to the fuel supply and the fuel injector governs the rate of fuel delivery by controlling the duration and frequency of an opening period of the fast acting valve.
