    摘要: An improved burner and a method for combusting fuel in a burner used in furnaces such as those found in steam cracking. The burner includes a burner tube having a downstream end and an upstream end, the burner tube having a venturi therein; a fuel spud located adjacent the upstream end of the burner tube, for introducing fuel gas into the burner tube; a burner tip mounted on the downstream end of the burner tube adjacent a first opening in the furnace; at least one passageway having a first end and a second end adjacent the upstream end of the burner tube; means for drawing flue gas from the furnace, through the passageway, in response to an inspirating effect of uncombusted fuel gas exiting the fuel spud, the uncombusted fuel gas flowing through the burner tube from its upstream end towards its downstream end; and means for increasing the inspirating effect of uncombusted fuel gas exiting the fuel spud. The means for increasing the inspirating effect of uncombusted fuel gas exiting the fuel spud is effective to increase the amount of flue gas drawn from the furnace.

    摘要: A highly efficient vapor/liquid separation apparatus for treating a flow of vapor/liquid mixtures of hydrocarbons and steam comprises a substantially cylindrical vertical drum having an upper cap section, a middle section comprising a circular wall, a lower cap section, a tangential inlet to introduce hydrocarbon/steam mixtures, an overhead vapor outlet, and a bottom outlet for liquid. The vessel also comprises an annular structure located in the middle section, comprising i) an annular ceiling section extending from the circular wall and ii) a concentric internal vertical side wall to which the ceiling section extends. The annular structure blocks upward passage of vapor/liquid mixtures along the circular wall beyond the ceiling section, and surrounds an open core having sufficient cross-sectional area to permit vapor velocity low enough to avoid significant entrainment of liquid.
