Abstract
A thermal processing plant having heating tubes that are arranged in a zigzag or undulating line in an oven chamber. Burners generate a gas stream which is directed against a wall of the oven opposite the wall in which the burners are positioned. The burners direct a gas stream at each of the wave or zigzag crests and in each of the wave or zigzag troughs. The thermal radiation of the oven wall and of the reaction zone (combustion heat) heats the heating tubes uniformly.
Claims9
A heating system comprising:
- a wall arrangement (2) that at least partially defines a heatable interior space (3),
- a plurality of heating tubes (4) disposed in said interior space (3) in parallel relation to each other for guiding a fluid to be heated;
- a plurality of burners (6) for heating the interior space (3), said burners being arranged perpendicular to said heating tubes (4) for directing heat toward a respective section (21) of said wall arrangement (2) opposite each burner (6), and
- said heating tubes (4) being arranged in a line (10) that has at least two sections (11, 12) that each open up away from the burners (6).
