摘要:
The invention relates to a shielding device which is intended to be placed onto the end of a gas-discharge pipe of a heating appliance and which has the purpose of shielding the gas-discharge pipe from rain and wind. To this end, the shielding device comprises a covering member which extends at a distance over a gas-conducting pipe (20). A shielding pipe (10) is arranged coaxially with the gas-conducting pipe (20), between the covering member and the gas-conducting pipe (20). A water-discharge opening (23) is defined between the gas-conducting pipe (20) and the shielding pipe (10). The shielding device further comprises a water-discharge member (30) which is situated between the gas-conducting pipe (20) and the gas-discharge pipe. An annular water-discharge opening (40) is defined between the gas-conducting pipe (20) and the water-discharge member (30). A covering cap (50) extends over the annular opening (40).

摘要:
Chimney, comprising a transport shaft (3) for waste gases which can be mounted protruding through a roof and which can be connected to an end shaft (1), mountable on top of the roof, being in communication with the open air at its top end, in which furthermore the diameter of the end shaft is larger than the diameter of the transport shaft, and comprising means with which the end shaft can be secured in such a way that the end shaft with its bottom end extends to a lower level than the top end of the transport shaft, so that the transport shaft protrudes into the end shaft.

Cheminée comportant des conduites de fumée concentriques (2, 4, 6) pour évacuer des gaz brûlés de différentes sources, le canal central (2) évacuant de préférence le gaz à la température la plus élevée, ladite cheminée possédant un capuchon (12) protégeant toutes les conduites de fumée.
摘要:
A chimney turncap is provided with interior lower drains (14) for guiding condensed water to a collector tray (6) located in the warm zone of the chimney top, whereby the water disappears by evaporation. The hood portion (8) is a semitubular element having a vane (16) placed so as to make the hood assume a position transversely to the wind, whereby the smoke leaves the hood crosswise through the opposite open ends thereof; in this manner the space underneath the hood member is shielded from the direct influence of the wind, such that sufficient heat can be retained for said evaporation. For the same purpose the hood even acts as a reflector for heat radiation from the chimney.

Ein Vorrichtung zum Abscheiden von Flüssigkeit im Innenbereich eines im wesentlichen vertikalen Rohrabschnitts (10a), insbesondere eines Fortluft- oder Abgasrohres (10), umfasst eine wendelartige Abscheidestruktur (16) mit einer Vielzahl von Wendelabschnitten (18), die entlang einer zumindest geometrischen Wendelachse (20) angeordnet sind, wobei jeweils zwei benachbarte Wendelabschnitte (18) in unterschiedlichen Drehwinkellagen zur Wendelachse (20) angeordnet sind. Jeweils zwei benachbarte Wendelabschnitte (18) sind derart miteinander verbunden, dass zwischen zwei Wendelabschnitten (18) wenigstens eine radial verlaufende Wendelkante (24) ausgebildet ist und die Abscheidestruktur (16) als durchgehende Abscheidewendel (26) mit einer Abscheideoberfläche (28) ausgebildet ist. Außerdem ist ein Rohr zum Abführen von Fortluft oder Abgas angegeben, bei dem im Innenbereich eines Rohrabschnitts (10a) eine solche Vorrichtung (14) zum Abscheiden von Flüssigkeiten angeordnet ist.
摘要:
An exhaust fan assembly is provided for expelling contaminated air from a building. The assembly includes a plenum, a fan assembly attached to the plenum, and a windband mounted on top of the fan assembly. The fan assembly is constructed of cylindrical outer and inner walls which define a bearing chamber and surrounding annular space. A fan driven by a shaft extending downward from the bearing chamber draws exhaust air from the plenum and blows it up through the annular space to a nozzle at the top of the fan assembly.
