Abstract
Heating device for the heating and gasification of urea or an urea solution, particularly for internal combustion engines, wherein said heating device is designed for installation in a gas line extending in a direction of flow and wherein said heating device has at least two gas-permeable heating surfaces that are spaced apart from each other in the direction of flow and that define a heating chamber. In order to create an improved heating device for stable urea gasification in an exhaust gas line that guarantees a uniform temperature distribution in the heating room as well as a quick response time, according to the invention an inlet opening is provided that discharges into the heating chamber between the at least two heating surfaces and through which the urea or urea solutions can be fed into the heating chamber.
