This invention relates generally to heating equipment

of course, serves the function of directing the heated
air within the heat chamber 16 along the cylindrical
wall 14 so that an e?icient heat exchange is established
between the air and wall 14. A plurality of projections,
as at 40, are secured to the wall 14 on the inner surface
The projections 40 project radially inwardly
and are all aligned along the same horizontal plane. Sup
