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 slightly 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 set of small and large jets, with small jets opposing large jets, and vice versa. The sizes of the jets may be regulated by varying opening size, number of openings in groups of openings, air pressure upstream of the openings, or combinations thereof.

Abstract: This invention improves gas mixing and combustion, gaseous fluid flow and control of the char bed in recovery boilers burning black liquor or soda liquor, requires fewer primary air ports than conventional methods and can reduce capital and operating costs. Some primary air is introduced as powerful principal jets, from two opposing so-called active furnace walls. All or most of the remainder of the primary air is introduced as smaller jets, called scavenging jets, which prevent char from accumulating in the furnace corners and, in some cases, between the principal jets and are in the same plane as the principal jets. The momentum flux of each of the principal jets is approximately double or more than double that of each scavenging jet. Some of the primary air may be introduced as central jets, from the remaining two furnace walls and located in the same plane as the other ports, or on a second, somewhat higher plane. The momentum flux of the central jets is less than that of the principal jets.

Abstract: This invention improves fluid flow, gas mixing and combustion in the furnaces of recovery boilers which burn liquor from various pulping processes, namely, the kraft process, the soda process, the sodium-based sulphite process, the closed-cycle CTMP (chemical, thermal, mechanical pulp) process, the magnesium-based sulphite process and the ammonium-based sulphite process, which are employed in the manufacture of pulp and paper, and in the furnaces of boilers burning biomass, wood waste or other solid fuel. The invention improves the operation of new or retrofitted boilers in several ways and can reduce both the capital and operating costs. One embodiment comprises introducing a portion of the combustion air, and/or recycled flue gas, at any elevation in the furnace, from two opposing walls only, as jets arranged in a partially-interlaced manner, with the jets oriented in a more or less common plane which is inclined. The partially-interlaced jets can be applied as primary air to improve performance and reduce capital costs.
