Abstract
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.
