    Abstract: Die Erfindung umfasst einen Kombinationsbrenner für die Vergasung staubförmiger Brennstoffe mit einem freien Sauerstoff enthaltenden Oxidationsmittel bei Umgebungs- oder höheren Drücken, sowie Temperaturen zwischen 800-1800 o C, wobei die Zündvorrichtung des Pilotbrenners mit Flammüberwachung und der Staubbrenner als Kombinationsbrenner integriert sind und alle Betriebskanäle voneinander getrennt bis zum Brennermund geführt und die von den Kanälen geführten Medien erst am Brennermund gemischt werden. Bei Demontage des Pilotbrenners können die auf seiner Hülle befestigten Wirbelkörper (14) in der Hauptbrenneroxydationsmittel-Zuführung (17) schnell und einfach gewechselt werden und somit die Hauptbrennerflamme optimal an die Reaktionsraumkontur des Reaktors angepasst werden.

    Abstract: A fuel head assembly (120) for a pulverized coal nozzle includes removeable back cover (123) that may be removed substantially horizontally to allow access to liners (141,143,145) inside of the fuel head assembly (120) for servicing. This may be used in places where there access from above the fuel head assembly (120) is restricted. The liners (141,143,145) are constructed of a wear-resistant material and include curved vanes (131,133) for more evenly distributing pulverized solid fuel particles, and for reducing erosion of the fuel head assembly (120).

    Abstract: A head assembly 52, 152 for a pulverized coal nozzle includes removeable wear-resistant inserts having vanes 54, 151, 153. The vanes 54, 151, 153 may be flat or curved to direct a stream of air and pulverized solid fuel particles from the inlet port 60, 160 toward the outlet port 62, 162. The curved vanes 151, 153 curve in two dimensions to evenly distribute the stream of air and pulverized solid fuel away from the outer surfaces reducing wear and corrosion. The pipe elbow has a removable cover 70, 170 that allows for easy access. The vanes are attached to a wear-resistant replaceable liner 185 thus allowing them to be easily removed and replaced. The wear-resistant liner 185 may be made from several parts 187, 189 for ease of removal and replacement.

    Abstract: 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.
