    • A (MRFC) solid fuel nozzle tip (12) that is particularly suited to being cooperatively associated with a pulverized solid fuel nozzle (34) of a firing system of the type employed in a pulverized solid fuel-fired furnace (10). The MRFC solid fuel nozzle tip (12) includes fuel air shroud means (46), primary air shroud means (48) located within the fuel air shroud means (46), fuel air shroud support means (50) operative for supporting the primary air shroud means (48) relative to the fuel air shroud means (46), and splitter plate means (52) mounted in supported relation within the primary air shroud means (48). The MRFC solid fuel nozzle tip (12) may be comprised of ceramics including silicon nitride, siliconized silicon carbide, mullite bonded silicon carbide alumina composite, and alumina zirconia composites.

    • Submerged combustion burners having a burner body (42) and a burner tip body (50) connected thereto. The burner body has an external conduit (44) and a first internal conduit (46) substantially concentric therewith. The external conduit and first internal conduit form an annulus (1) for passing a cooling fluid there between. A second internal conduit (48) 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 (70) and a crown (54) 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)和与其连接的燃烧器末端体(50)的浸没燃烧燃烧器。 燃烧器本体具有与其基本同心的外部导管(44)和第一内部导管(46)。 外部管道和第一内部导管形成用于在其间通过冷却流体的环形空间(1)。 与外部管道基本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。 燃烧器末端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体的内壁限定。 燃烧器末端体还具有连接内壁和外壁的外壁(70)和表冠(5​​4)。 冠包括至少一个足以增加表冠的表面积和抗疲劳性的物理卷积。
