Patent ID: 8033531

Claim:
An apparatus for mixing a liquid with a large gas stream flowing in a gas duct, comprising: at least one metering lance having at least two atomizer nozzles for supplying the liquid to the gas stream, wherein an axis of each of said at least two nozzles is disposed at an angle relative to a direction of flow of the gas stream, and wherein said atomizer nozzles are inclined in opposite directions relative to one another to form an atomizer angle; and at least one disk-shaped mixer element associated with and spaced relative to said at least two atomizer nozzles, wherein said mixer element is disposed at an angle relative to the direction of flow of the gas stream , further wherein flow eddies are adapted to form at said at least one mixer element, further wherein at least a portion of the liquid is adapted to enter the flow eddies, further wherein atomization is effected in such a way that volatilized gaseous portions contained in nozzle streams respectively exiting said atomizer nozzles enter said flow eddies, while non-volatilized droplet portions, due to their inertia and said atomizer angle, do not enter said flow eddies in the vicinity of said at least one mixer element, wherein said atomizer nozzles, relative to said gas stream, are disposed downstream or upstream of said at least one mixer element.
