Distribution device for secondary air in a heating apparatus

摘要

The invention describes a distribution device (30) for secondary air in a heating installation (1) having a supply air-regulating device (19), having a combustion chamber (2) and outflow openings for secondary air which open into the upper part of said combustion chamber, are connected to a secondary-air duct and are arranged in the combustion chamber (2) in the region of the top edge (20), assigned to an upper side of a door arrangement (12), of a door cutout (21) of the heating installation (1), the distribution device (30) being arranged on a floor plate and/or grating plate (8) of the combustion chamber (2) at least in the region of the door cutout (21). The said device has a partition wall (37) which is situated at a distance from the inner side of the door facing the combustion chamber, extends in the direction of the top edge (20) of the door cutout (21) and forms an air-distributing duct (36) between the inner side of the door and the partition wall (37), which air-distributing duct is connected to the combustion chamber (2) in the region of the floor plate and/or grating plate (8) via an opening (54). The partition wall (37) is arranged, via vertical supporting elements (57), with a bottom edge (53) facing the grating plate (8) at a distance above a floor guide plate (38) in the vertical direction and is connected to the latter. The floor guide plate (38) extends from the grating plate (8) of the heating installation (1) in the direction of its cover plate and is inclined with respect to the outer casing, a distance between this floor guide plate (38) and the door arrangement (12) with ...
