| titleOfInvention | SMOKE GAS CHANNEL FOR GRAND BOILER WITH A DEVICE FOR FEEDING AMMONIA IN THE FLUE GAS FLOW |
| abstract | Ammonia gas is introduced by means of a feeding device into the flue gas duct of a large boiler, for example of a power station, having a flow cross-section of at least 3 m<2>, into the flue gas stream flowing through the flue gas duct at a flow velocity of 10 to 30 m/s for a subsequent reduction, in particular a selective catalytic reduction, of the nitrogen oxides contained in the flue gas to nitrogen and water at a temperature of 300 to 450 DEG C. Hitherto, an ammonia/air mixture has been introduced through nozzles distributed over the cross-section of the flue gas duct at about the flow velocity of the flue gas, a distribution grid being provided downstream thereof, if desired. In order to effect the ammonia feed with higher operational reliability and lower energy consumption and to achieve a perfect and more complete mixing over a comparatively short mixing length, it is provided that the feeding device has jet pipes 7, ending in the direction of the flue gas flow in the flue gas duct 1, for feeding flue gas under pressure at a rate of 1 to 5 % by volume of the flue gas stream and at a flow velocity of at least 80 m/s at the jet pipe end, the jet pipes being connected to a flue gas compressor (2) which draws the flue gas from the flue gas duct via a flue gas branch line (3) and draws the ammonia gas. <IMAGE> |
