Abstract:
Post-combustion conditioning systems are described that include a flue gas conditioning device configured to condition an exhaust stream to produce a conditioned stream. First and second outlet ducts can be fluidly coupled to, and substantially supported by, the flue gas conditioning device. This advantageously can eliminate costly ductwork, reduce the space required, and reduce the pressure drop of the system. The first outlet duct can fluidly couple the flue gas conditioning device to an exhaust duct, such that the conditioned stream can flow from the first conditioning device via the first outlet duct.
Abstract:
A splitter plate arrangement is provided for controlling the flow of flue gas in a vertical stack. The splitter plate arrangement (100) is operable to control the flow of flue gas in a vertical stack (128) having an annular entry (130) communicated with two inlets (126A, 126B) which each communicate a respective one of the flue gas producers with the vertical stack (128). The inlets (126A, 126B) are both disposed on a common inlet axis which bisects the annular entry (130) into two bisected halves, the two inlets (126A, 126B) are oriented in opposition to one another such that the inlet flow (132) of flue gas through the inlet (126A) flows in a direction opposite to the inlet flow (134) of flue gas through the inlet (126B). The splitter plate arrangement (100) includes a first splitter plate (136) and a second splitter plate (138). The first splitter plate (136) extends radially inwardly from the inner surface of the vertical stack (128) at generally the midpoint MDOT of one bisected half of the annular entry (130) of the vertical stack on one respective side of the inlet axis (1A). The second splitter plate (138) extends radially inwardly from the inner surface of the vertical stack (128) at generally the midpoint MDOB of the other bisected half of the annular entry (130) of the vertical stack (128) on the other respective side of the inlet axis 1A.
Abstract:
The invention relates to a fume treatment device (10) for use in a chimney flue (3) of a boiler (2), said flue having a minimum project section (A). The device comprises a branch-off (32) that divides the flue (3) into a main duct (30) and a by-pass pipe (31 ), and a purifier assembly (11 ) positioned along said by-pass pipe (31 ). The branch-off (32) is static and the main duct (30) is completely open for passage therethrough during normal boiler operation.
Abstract:
Internal collars and external saddle taps can be used to install taps on a main duct in a manner that maintains duct section joint integrity. A saddle tap assembly may include an external slip tap, internal tap collar, a duct section, and adhesive. The external slip tap and the internal tap collar may each have a flange. The flanges may be curved. The flange of the internal collar may have a sheared portion permitting the flange of the internal collar to pass through an opening in a section of duct. The duct may have an opening with one or more notches. A method of installation can be more efficient and more cost-effective than prior solutions. An installation tool can be used for installing saddle tap assemblies while an adhesive cures.
Abstract:
A venting apparatus includes a projecting member with a projection base, and a mating socket member with a socket base, and first and second ducts in fluid communication with an appliance to vent emissions along an emission flow path. The projection base engages a first one, and the socket base engages a respective other one, of the first and second ducts. The projecting and socket members have default configurations. The projecting member is movable from the default configuration towards a deflected configuration, and biased for return therefrom. The first and second ducts are movable between sliding and locked configurations. In the sliding configuration, the projecting and socket members bear against one another, with the projecting member removed from the default configuration. In the locked configuration, the projecting member is in the default configuration, and secured to the socket member, such that the second duct securely engages the first duct.
Abstract:
A two-part clamp-connected chimney flue tee. The tee includes an elongated main section which is detachably connected to a transversely extending bull, or snout section. The main section has flue pipe connection ends and an oval cut-out portion in its sidewall, generally midway between the connection ends. The periphery of the cut-out includes an outwardly flaring flange, for mating with a corresponding contoured end of the bull section. Hooks are mounted on the inner sidewall of the main section, on opposing sides of the cut-out. Lever-actuated clamps, having a U-shaped locking member, are mounted on opposing inner portions of the sidewalls of the contoured end of the bull section. In mating the two sections, the bull section is press-fitted over the flange surrounding the cut-out. A locking member on one side of the contoured end is engaged with a respective hook. Then, the lever on the clamp is snapped toward the adjacent sidewall, into a locked position. The process is repeated for the locking member, the hook, and the lever on the other side of the conjunction, to secure the two sections firmly together.
Abstract:
The adjustable pipe fitting of the invention has double walls in accordance with Type B standards established by the American National Standards Institute and Underwriters Laboratories. In the preferred embodiment, the invention comprises a main conduit having three sections which are rotatably coupled together. A branch conduit is securely connected to the main conduit so that fluid communication exists between the branch and main conduits. The branch conduit also comprises three sections which are rotatably coupled together. The main conduit sections and the branch sections are coupled together at oblique angles relative to their respective longitudinal axes to provide a means for adjusting the fitting to accommodate connector pipes having various angles and orientations.
Abstract:
Eine Vorrichtung zum gasdichten Anschluß eines Abgasrohrs (22) an einem Anschlußstutzen (3). Die Vorrichtung weist einen Endabschnitt (18) auf, der mindestens eine ringförmige, radial nach innen ragende Dichtlippe (16) trägt. Deren Abstand von dem Stirnrand des Anschlußstutzens (3) ist so bemessen, daß die Dichtlippe bei ihrer elastischen Verformung durch Einschieben eines Abgasrohrs (22) auslenkbar ist, ohne in den Ringspalt (24) zwischen dem Abgasrohr und dem Anschlußstutzen zu gelangen. Dadurch wird ein das Einschieben des Abgasrohrs verhinderndes Einklemmen der Dichtlippe unterbunden (Fig. 2).
Abstract:
Ein Rohrleitungs-Formstück für Abgasanlagen für Brennwertgeräte weist einen Rohrgrundkörper (1) auf, der an seinem Austrittsende eine Rohranschlußmuffe (2) und an seinem anderen Ende sowie in seiner Seitenwand jeweils eine Anschlußöffnung (4,5) hat. Der Rohrgrundkörper (1) ist an den beiden Anschlußöffnungen (4, 5) jeweils mit Außengewinde (6) versehen. Ein Muffenanschlußstutzen (7) ist mittels eines Gewinderings (8) wahlweise mit einer der beiden Anschlußöffnungen (4, 5) verbindbar ist. Ein Verschlußstück (9, 9', 11) ist auf die jeweils andere Anschlußöffnung (5, 4) aufschraubbar. Das Verschlußstück ist beispielsweise ein geschlossener Deckel (9).
