Abstract

An analytical investigation was conducted to examine how the mass flow is distributed into multiple flow circuits with partial contractions in flow passages. It is usually considered by conventional practices in fuel supply system of gas turbines that the fuel flow distribution in multiple fuel circuits is determined by the opening area of staging valves. This study extends this conventional concept by considering the coupled effect of staging valves with burner nozzles. A two-branch flow system was demonstrated to illustrate how the mass flow is distributed by the opening of staging valves and burner nozzles, and vice versa, i.e., how the staging valve opening scenario should be implemented to satisfy a prescribed flow split schedule. The concept accounting for the coupled effect was then applied to the fuel supply system of an industrial gas turbine combustor with multiple burner nozzles to design an opening scenario of the fuel staging valves.
