Air supply device for heating device, has outflow openings for supplying primary and secondary air and formed on two regions of outer surface of nozzle-shaped shaft, respectively, and common supply channel arranged within combustion chamber
The device has outflow openings (5) for supplying primary and secondary air and formed on two regions of an outer surface (7) of a nozzle-shaped shaft (6), respectively. The openings are attached to a secondary combustion chamber (4). A common supply channel for supplying the primary and secondary air is arranged within a primary combustion chamber (3), and an air guiding channel is arranged on a base (8) of the primary chamber. The openings are formed as longitudinal slots that are formed around a longitudinal axis of the shaft. The outer surface is surrounded by a heat shield.
