In 2011 we proposed that the Hβ lines are formed in a Failed Radiatively Accelerated Dusty Outflow (FRADO). In this paper we investigate this mechanism in more detail. We calculated the motion of dusty clouds taking into account the dust evaporation which arises when they are additionally illuminated by the central source. Our model explains the location and extension of the Broad Line Region as well as its large turbulent motion superimposed on Keplerian rotation. However, an enhancement of the dust opacity or additional mechanisms are necessary to push the material high enough above the disk.
