Abstract

A device (1) for evaporating a urea-water solution, having a delivery duct (2) for the urea-water solution, said delivery duct extending through at least a first zone (3) and a second zone (4) for the introduction of heat energy, wherein the zones can be heated separately from one another, and, in the second zone (4), the delivery duct (2) initially has a meandering profile (7) in a second inlet region (6), and thereafter has a rectilinear profile (8). Also proposed is a method in which the urea-water solution is pre-heated in the first zone (3) to a temperature in the range from 100°C to 150°C, and is evaporated in the second zone (4) at a temperature in the range from 420°C to 490°C. In particular, the tendency for such an exhaust-gas-external evaporator for a urea-water solution to become blocked is significantly reduced in this way. Fig. 1
