    • Heating means for a drier comprising a first heating channel 3 and a second heating channel 4 each having an inlet portion with an inlet opening 6, 10 and an outlet portion with an outlet opening 7, 11, and a burner 1 projecting into the first heating channel 3 via the inlet opening 6 thereof and having a burner head 2 disposed in the first heating channel 3. The cross-sectional area of the second heating channel 4 is greater than that of the first heating channel 3 and the outlet portion of the first heating channel 3 projects into the inlet portion of the second heating channel 4 wherein the first heating channel 3 is offset towards a lower side of the second heating channel 4. There may be a flow guide means 15 provided in an upper part of the first heating channel 3 formed by an inwardly deformed portion 16 of the wall of the first heating channel 3. The burner head 2 may be arranged in a lower part of the first heating channel 3. There may be a deflecting channel 5, comprising an inclined surface, connected with the outlet opening 11 of the second heating channel 4 arranged to upwardly deflect gases. There may be an air conveying means 22 provided downstream of the outlet opening 11 of the second heating channel 4.

The flow guide means 15 may be formed by an inwardly deformed portion 16 of the wall of the first heating channel 3. The first heating channel 3 may be offset towards a lower side of the second heating channel 4. The burner head 2 may be arranged in a lower part of the first heating channel 3.
