Burner frequency dependent oscillation investigation behavior procedure uses sound absorbent chambers with acoustically matched connections and modulated fuel inputs

摘要

A burner (13, 14, 15) frequency dependent oscillation investigation behavior procedure uses a sound absorbent burner chamber (2) and prechamber (7) with acoustically matched connections (24, 25) and impresses phase and amplitude offset modulations on the fuel flow (19, 20) for measurement of the modulation of the exhaust gas mass flow (6). Includes INDEPENDENT CLAIMs for equipment using the procedure.
