Abstract
This invention is directed to a method and apparatus for improving fluid flow and gas mixing in boilers. More particularly, this invention pertains to a method and apparatus for improved fluid flow and gas mixing in kraft recovery boilers for increased energy efficiency, reduced TRS emissions and increased capacity. The method of introducing air into a boiler furnace comprises: (a) introducing air through at least one opening located on at least a first wall of the interior of the furnace; and (b) introducing air through at least one second opening located on a second wall of the interior of the furnace opposed to the first wall at the same, or different, elevations. The method of introducing air into a boiler furnace may also comprise: (a) introducing air into the furnace in the form of a first set of small and large jets originating from one wall of the interior of the furnace; and (b) introducing air into the furnace in the form of a second set of small and large jets originating from the wall of the interior of the furnace opposite the first wall. The locations of the sources of the first set of small and large jets may be placed so that they oppose the sources of the second se…
