Abstract:
A condensing boiler (1) comprises a heat exchanger (5) having a cylindrical first heat exchange wall (6) surrounded by an outer water chamber (10). A plug (17) extends into the first heat exchange wall (6) and forms a combustion chamber (22) and an annular downwardly extending flue gas passageway (23) for accommodating flue gases from the combustion chamber (22). The plug (17) comprises an outer shell (18) which forms a second heat exchange wall (19) and an inner cylindrical shell (35) which forms with the outer shell (18) an inner water chamber (36). A connecting pipe (46) connects the inner water chamber (36) to the outer water chamber (10) so that water flows in series through the inner water chamber (36) and the outer water chamber (10) from a return water inlet (42) in the inner water chamber (36) to a flow water outlet (16) from the outer water chamber (10).
Abstract:
A heat exchanger (10) comprises a front wall (20) and a back wall (30) to form a space (40) for a flue gas, and a front channel (60) and a back channel (70) formed in the front wall (20) and the back wall (30), respectively, in which a fluid is to flow. The heat exchanger (10) is configured such that the fluid in the front and back channels (60, 70) can exchange heat with the flue gas, in use. The entire back wall (30) extends along a first plane (P1). The front wall (20) includes a lower portion (22) and an upper portion (24). The lower portion (22) extends upwardly along the back wall (30). The upper portion (24) extends upwardly from the upper end of the lower portion (22) and extends outwardly away from the back wall (30) so as to form a combustion space (42) of a flammable gas between the upper portion (24) and the back wall (30). The heat exchanger (10) is further configured such that the volume flow rate and/or mass flow rate of the fluid in the front channel (60) is greater than the back channel (70), in use.

Abstract:
The heat exchanger comprises at least one gas flow channel, at least one water flow channel, and a metal wall delimiting the gas flow channel from the water flow channel. The at least one water flow channel comprises a number of consecutive parallel straight segments. Two consecutive parallel straight segments are separated by a wall and by a U-turn comprising an upstream section and a downstream section. The upstream and the downstream sections are defined as the sections of the U-turn delimited on the one hand by the plane of the wall separating the two consecutive parallel straight segments; and on the other hand by the plane through the end section of the wall separating the two consecutive parallel straight segments, the plane which is parallel with the width direction of the water flow channel and which is perpendicular to the plane of the wall separating the two consecutive parallel straight segments. In at least two U-turns the upstream section has a volume that is at least 20% lower than the volume of the downstream section.
