Fuel distributor/flameholder for a duct burner
This paper discusses equal length, radially oriented, transverse spraybars for distributing fuel into a stream of gas flowing in a cylindrical duct burner and stabilizing a resulting combustion reaction. It comprises an elongated tapered portion extending into the gas stream to a central, coaxial pilot region therewithin, the tapered portion having a flow profile diminishing directly with respect to inward radial displacement, a tip portion, disposed radially inward of the tapered portion and within the pilot region, the tip portion having a transversely flared flow profile to induce turbulence in a portion of the gas stream flowing through the pilot region for holding the combustion reaction to the spraybar, and means for selectively and independently discharging fuel into the gas stream from the tip and tapered portions of the spraybar.
