    摘要: On décrit un élément de remplissage en forme de selle (10) destiné à être utilisé dans une tour vapeur/liquide, ledit remplissage comprenant un corps arqué doté de part et d'autre de brides verticales (12, 13) généralement parallèles. Le corps arqué comporte une pluralité d'éléments arqués à nervures intérieures (16) et extérieures (18) alternantes, généralement parallèles, s'étendant transversalement entre les brides. Le procédé de fabrication de l'élément de remplissage consiste à refendre une feuille de métal plane afin de former des éléments à nervures, à replier la feuille pour former les brides verticales et les éléments arqués à nervures, et ensuite à leur conférer la forme arquée du remplissage.

    摘要: Improved gas burner apparatus and methods of burning fuel gas-air mixtures are provided whereby flue gases having low NO X contents are formed. The burner apparatus includes a refractory burner tile (30) having an air discharge opening (34) therein and a wall (36) surrounding the opening which extends into the furnace space and provides a mixing zone therein. At least one passage (54) is formed in the burner tile which opens into the mixing zone and fuel gas is jetted through the passage whereby flue gases are drawn therethrough and a fuel gas-flue gases mixture is discharged into the mixing zone. The fuel gas-flue gases mixture is swirled in the mixing zone and mixes with air therein, and the resulting mixture is discharged and burned in a primary reaction zone in the furnace space.

    摘要: An improved mist eliminator (20) for use in a column for removing liquid from a gas stream. The mist eliminatorcom- prises a plurality of spaced apart chevron-type baffle members, the baffle members defining a plurality of gas flow paths therebetween and transversely disposed to the axis of the column. The upstream leading edges of the chevron-type baffle members present a plurality of downwardly extending drainage teeth (42) thereon to promote the rapid drainage of coalescent liquid from the chevron-type baffle members thereby increasing the critial or maximum allowable velocity of the gas stream and the gas capacity of the chevron-type baffle members and decreasing the pressure drop across the mist eliminator.
