Abstract
A feed device for supplying solid urea granules into an ammonia generator arranged within or outside of an exhaust line for production of ammonia makes possible NOreduction with the catalytic purification of exhaust of an internal combustion engine, gas turbine, or a burner, whereby the solid urea granules are stored in a holding tank. No compressed air support for transporting and metering the urea granules is required and transporting and metering of the urea granules adapted to the ammonia specifications is possible. The feed device has a housing with an inlet for supplying the urea granules and internally, a motor-driven, rotating disk with at least one spiral-shaped acceleration channel, as well as an outlet leading outward, to which a tube leading to the ammonia generator is connected.
