摘要:
A flexible hose liner is provided having a cylindrical body extending along a longitudinal axis from a first end to a second end. First and second sleeves form the cylindrical body by separate continuous ribbons having a plurality of convolutions formed in a helical pattern along the cylindrical body from the first end to the second end. A ring is formed in each revolution about the longitudinal axis of the continuous ribbon of the first and second sleeves. A plurality of rings form the cylindrical body, each ring has a first convolution and an ending convolution such that a mechanical connection is formed between the ending convolution of a preceding ring and the first convolution of a succeeding ring. The mechanical connection of the between the rings of the first sleeve being different from the mechanical connection of the rings of the second sleeve.
摘要:
A combination insulated flue and thermosyphon chimney having an inner flue conduit, a first liner member surrounding the conduit to form an air inner annulus therebetween, and a second liner member surrounding the first liner member to form an air outer annulus between the first and second liner. An insulation is connected to the inner fluid conduit to insulate the inner air annulus from the flue conduit. A shell member surrounds the insulation to separate the air inner annulus from the insulation. Brackets are provided to connect the shell member with the first liner, and the first liner with the second liner.
摘要:
Disclosed is an improved assembly of orifice chambers for reducing pressure of large gas flows effective to reduce noise of the gas flows and wear on orifice chambers by progressive pressure drops in the gas flows through successive orifice plates which are releasably secured, preferably by fillet welding, in each of the orifice chambers, removal of one or more orifice plates in an orifice chamber providing manway access to the next succeeding orifice chamber for inspection, repairs, and replacement of the orifice plates thereby reducing the manway opening or access to only one orifice chamber and eliminating separate access manways or manholes for each of the orifice chamber necessary for maintenance of the orifice chambers. Preferably, an internal shell providing an annular space with the body to which the orifice plates are connected is connected to the body by an annular ring and brace by fillet welding in compressions.

Flexible piping includes a first, spiral-wound band forming an inner winding and a second, spiral-wound band forming an outer winding in covering relationship over the inner winding. Inner and outer spiral-wound bands of insulating material are wound between the inner and outer windings and over the outer winding respectively. An insulating sleeve receives the spiral-wound inner and outer windings and the inner and outer insulating material bands. A method and a machine for forming the flexible piping are also disclosed.
摘要:
An emergency exhaust system (59) is provided for a mobile incineration system (10). A hinged gate (76) controls access to the emergency exhaust system (59), and operates only upon the sensing of a malfunction in one of a plurality of critical incineration system components (114, 36, 56) by sensors/relays (122-126). A malfunction as sensed by Sensors/relays (122-126) causes the power to be cut through switch (98) to the main incineration system components (114, 36, 56, 46, 116, 118, 22). In a preferred embodiment, the emergency exhaust system (59) comprises a plurality of water sprayers (64) to cool the volatile waste combustion products, and a granulated activated carbon column (68) to remove hazardous substances.

A heated vent cap assembly is provided which can be coupled to a pipe originating from a plumbing system within a building. A heating element is wound around an inner cylinder which is wrapped in a conductive foil and enveloped by a larger diameter outer cylinder which is lined with a reflective foil defining a void there between. The cylinders are secured at an upper end by an end cap and at a lower end by a lower end cap and a tether is tautly secured within the inner cylinder by a bridge in an opening of the end cap and a lower disk engaged with the lower end of the inner cylinder to support ice blocks formed therein. The heating cable generates heat, which is reflected by the reflective foil and absorbed by the conductive foil to prevent ice from forming on the inner surface of the inner cylinder.
摘要:
A housing of a device for the treatment of gases hotter than the ambient temperature, in particular flue gases, comprises an exterior frame made of supports. At the interior side of said frame an insulating wall is arranged which comprises an interior side metal sheet and an exterior side metal sheet, wherein insulating material having an extremely low heat conductivity is arranged between said metal sheets.
