COMBINED HEAT EXCHANGING AND FLUID MIXING APPARATUS

摘要

The combined heat exchanging and fluid mixing apparatus comprises a first conduit (44) for guiding a cool fluid through the first conduit and a second conduit (55) for guiding a hot gas through the second conduit. A heat conductive element (2) is arranged between the first conduit (44) and the second conduit (55) for transferring heat from the hot gas to the cool fluid. The heat conductive element has a length defining a maximum longitudinal extension (22) for a heat exchanging process in the apparatus. The apparatus further comprises a third conduit (45) for guiding an exhaust fluid. The third conduit (45) comprises an exhaust fluid inlet (46) for introducing an exhaust fluid into the apparatus for mixing of the exhaust fluid with the hot gas and for a chemical reaction of the so formed exhaust fluid/hot gas mixture in the second conduit (55). The third conduit (45) is provided with more than one openings (21) passing the exhaust fluid into the second conduit (55). The more than one openings are arranged within the maximum longitudinal extension (22) for a heat exchanging process in the apparatus and at substantially a same longitudinal position with respect to the second conduit (55).
