Abstract

A heating configuration for a drier, particularly for a laundry drier, has a burner with a burner head, a first heating channel with an inlet opening and an outlet opening, and a second heating channel with an inlet opening and an outlet opening. The cross-sectional area of the second heating channel is greater than the cross-sectional area of the first heating channel. The burner head projects into the inlet opening of the first heating channel and the outlet opening of the first heating channel projects into the inlet opening of the second heating channel. The first heating channel is disposed in the lower section of the second heating channel so that a uniform temperature distribution is achieved in the second heating channel.
