    • Submerged combustion burners having a burner body and a burner tip body connected thereto. The burner body has an external conduit and a first internal conduit substantially concentric therewith. The external conduit and first internal conduit form an annulus for passing a cooling fluid there between. A second internal conduit substantially concentric with the external conduit forms a second annulus between the first and second internal conduits. A burner tip body is connected to the burner body at ends of the external and first internal conduits. The burner tip body includes a generally central flow passage for a combustible mixture, the flow passage defined by an inner wall of the burner tip body. The burner tip body further has an outer wall and a crown connecting the inner and outer walls. The crown includes at least one physical convolution sufficient to increase surface area and fatigue resistance of the crown.
    • 具有燃烧器主体(42)和连接到燃烧器主体(50)的浸入式燃烧器。 燃烧器本体具有外部导管(44)和与其基本同心的第一内部导管(46)。 外部导管和第一内部导管形成用于在其间传递冷却流体的环形空间(1)。 与外部导管大致同心的第二内部导管(48)在第一和第二内部导管之间形成第二环形空间。 燃烧器端部本体在外部和第一内部管道的端部连接到燃烧器本体。 燃烧器末端主体包括用于可燃混合物的大致中央的流动通道,该流动通道由燃烧器末端主体的内壁限定。 燃烧器头本体还具有连接内壁和外壁的外壁(70)和顶部(54)。 冠包括至少一个足以增加冠的表面积和抗疲劳性的物理卷积。
