Abstract: A condensing boiler condensate discharge device includes a hollow body having a peripheral wall, a first longitudinal end and a second longitudinal end. An inflow opening is provided in the peripheral wall and extends starting from the first longitudinal end in the direction of the second longitudinal end. A drain opening is provided in the peripheral wall. A separating wall is provided within the hollow body and extends from the first longitudinal end in the direction of the second longitudinal end and has a free end. The separating wall divides the hollow body into a condensate receiving channel, and a condensate discharge channel. The condensate receiving channel and the condensate discharge channel are flow-connected to each other via a passage. The drain opening and the inflow opening are arranged to be overlapping with an overlap length as viewed in the longitudinal direction.

Abstract: A heat exchanger tube of a heating boiler, comprising an outer tube, which may be flown through by exhaust gases from the boiler firing and which may be surrounded by boiler water on the outside, and a profiled insert inserted into the outer tube, which comprises ribs running in longitudinal direction of the outer tube to enlarge the inner surface of the outer tube and which is in thermally conductive contact with the outer tube, are to achieve that an even greater heat transfer capacity from the combustion gases to the boiler water in the heating boiler is enabled. A first longitudinal section of the outer tube is formed in a cylindrical, smooth-walled manner and a second longitudinal section of the outer tube has at least one cross-sectional narrowing element narrowing the flow cross section. The profiled insert extends exclusively over the first longitudinal section of the outer tube.
