    • The present invention relates to an isolated polypeptide having xylanase activity from Aspergillus fumigatus with a molecular weight of approximately 50 kDa by SDS-PAGE and homologous polypeptides thereof comprising an amino acid sequence having at least 95% identity with amino adds 20 to 397 of SEQ ID NO: 6; encoded by a polynucleotide comprising a nucleotide sequence having at least 95% identity with nucleotides 107 to 1415 of SEQ ID NO: 5: or encoded by a polynucleotide that hybridizes under high stringency conditions with (i) nucleotides 107 to 1415 of SEQ ID NO: 5, (ii) the cDNA sequence of (i), or (iii) a full-length complementary strand of (i) or (ii). The present invention also relates to a method for producing such polypeptides having xylanase activity comprising: (a) cultivating a wild-type Aspergillus fumigatus cell under conditions conducive for production of the polypeptide; and (b) recovering the polypeptide.

    • A static mixer is described in which rows of mixing plates are used in a combination with nozzles that are located with respect to the mixing plates in a manner that is designed to produce a high level of mixing without significantly impeding the flow of flue gas passing through the rows of mixer plates. In various embodiments, the static mixer includes rows of tilted plates, and the injection lance nozzles are positioned to align with row boundaries corresponding to the boundaries between consecutive rows of mixing plates. In some embodiments, there are N rows of mixing plates and N-1 rows of nozzles. In some embodiments the nozzles are positioned to coincide with the boundaries between rows. The mixer assembly including injection nozzles and/or lances can be implemented in a relatively compact manner allowing for it to be placed in a shorter length of flue than many other mixer assemblies.
    • 描述了一种静态混合器,其中混合板行与以相对于混合板定位的喷嘴组合使用,其设计成可以产生高水平的混合,而不会显着阻碍通过的烟道气的流动 搅拌板排。 在各种实施例中,静态混合器包括一排倾斜板,并且喷射喷枪喷嘴被定位成与对应于连续排混合板之间的边界的行边界对齐。 在一些实施例中,存在N排混合板和N-1排喷嘴。 在一些实施例中,喷嘴被定位成与行之间的边界重合。 包括注射喷嘴和/或喷枪的混合器组件可以以相对紧凑的方式实现,使其能够被放置在比许多其它混合器组件更短的烟道长度上。
