Abstract
A device for producing ammonia from urea pellets includes a pellet dispensing device, a pellet accelerator, a pellet shooting channel, and an ammonia reactor having a chamber or zone for shooting in urea pellets and a pellet deflector arranged on an end of the shooting path. The device further includes a urea pellet evaporation device and a hydrolytic catalytic converter. The urea pellets are removed from the reservoir in a regulated number/quantity by a dispensing device and transported to the accelerating device, where the pellets are moved from the pellet shooting channel into the ammonia reactor, where they are broken down into small pieces by impacting a pellet deflector at the end of the shooting path. The pieces are converted into a gas mixture containing ammonia and isocyanic acid by means of a urea evaporation device. The isocyanic acid is subsequently converted into ammonia and carbon dioxide.
