Abstract (en)

[origin: EP0915304A2] The triple-draft boiler has a guide plate (7) with legs (7) at both sides of the center vertical of the housing (4), at the center zone of the plate. The leg matches the shape of the housing, and has at least one row of space outflow openings (9) across the plate width (B). The outflow openings are slits with guide tabs (9'), angled downwards to extend into the back flow gap between the guide plate and the housing wall. At least one row of holes (8) is at the straight leg section (11) of the guide plate.
