Abstract:
A burner assembly including a housing having an air inlet, a burner end having an opening, a longitudinal axis extending generally from the air inlet toward the burner end, a motor, an impeller mounted in the housing and being in fluid communication with the air inlet, operatively connected to the motor and adapted to direct air from the air inlet toward the burner end, a coal tube adapted to convey coal toward the burner end, a coal inlet adapted to convey coal to the coal tube, a first bluff body ring, a second bluff body ring and a third bluff body ring mounted at the burner end, a flame bridge disposed between the first bluff body ring and the second bluff body ring, and an igniter mounted in the burner end and being adapted to ignite the air and fuel mixture in the burner end to produce a main flame.
Abstract:
A dust collection assembly includes a primary collection assembly and a secondary collection assembly and may be connected to a source of gas having dust entrained therein. The primary collection assembly includes a primary duct having an inlet end and an outlet end. A first apparatus is mounted within the primary duct imparts a swirling motion to the gas which enters through the inlet end of the duct. A second apparatus is located downstream of the first apparatus for removing a portion of the dust entrained in the gas. The secondary collection assembly is in fluid communication with the outlet end of the primary collection assembly, and it includes a plurality of filter bags. The dust collection assembly also includes a fan that is in fluid communication with the secondary collection assembly.
Abstract:
A mixing tube assembly having an inlet end and an outlet end and being adapted for use in a burner assembly. The mixing tube assembly comprises a substantially cylindrical outer wall which defines an interior open space. The mixing tube assembly also comprises a turbulator that is disposed in the interior open space defined by the substantially cylindrical outer wall. A method for mixing fuel and air in a burner assembly comprising providing a mixing tube assembly. The preferred method also comprises conveying fuel and air from the inlet end of the mixing tube assembly to the outlet end of the mixing tube assembly.
Abstract:
A burner assembly including a housing having an air inlet and a burner end, a motor, and an impeller mounted in the housing. The impeller is in fluid communication with the air inlet, in mechanical communication with the motor, and adapted to direct air from the air inlet towards the burner end of the housing. The burner assembly also includes at least one pre-mix gas injection nozzle mounted in the housing. Each of the at least one pre-mix gas injection nozzle has at least one orifice adapted to direct gaseous fuel into the housing. The burner assembly further includes a spin vane comprising at least one spin vane blade. The spin vane is mounted in the burner end of the housing and adapted to direct the flow of air in the burner end. The burner assembly still further includes an igniter mounted in the burner end of the housing. The igniter is adapted to ignite the air and fuel mixture in the burner end of the housing to produce a main flame.

Abstract:
A wall forming system that uses a pair of panels in combination with a furring strip assembly and retainer The pair of panels are placed in spaced relation using the combination of the furring strip assembly and the retainer wherein the furring strip assembly holds the exterior of the panels while the retainer is disposed between the panels to hold them at a predetermined distance. By holding the panels at a predetermined distance concrete is poured within the cavity formed between the panels to create a wall.
Abstract:
A mixing section adapted for use in a burner assembly comprising a plurality of mixing tube assemblies each comprising a substantially cylindrical outer wall which defines an interior open space and a plurality of holes which are disposed adjacent to the inlet end of each of the mixing tube assemblies. Preferably, air is conveyed from the inlet end to the outlet end of the mixing tube assemblies, fuel is conveyed to the interior open space defined by the substantially cylindrical outer wall through the plurality of holes, each of the mixing tube assemblies separately mixes an amount of fuel and air, and the mixing section is adapted to produce a mixture of fuel and air. A method comprising conveying fuel and air from the inlet end of the mixing tube assembly to the outlet end of the mixing tube assembly and mixing gaseous fuel and air in the assembly.
Abstract:
A coupler 10 for coupling two conduits 12, 14 is disclosed. The coupler 10 includes a female open ended tubular member 16 and a male open ended tubular member 18. Each tubular member 16, 18 has a joint end 20 and a conduit connection end 22, 24 between which an axial flow path extends. The conduit connection end 22, 24 is for connecting the tubular member to an end of a conduit such as a drain pipe. The coupler 10 further includes a jointing arrangement 34 for connecting the joint ends 20 of the tubular members 16, 18 to each other. The arrangement 34 includes a coaxial spigot formation 26 at the joint end of the male tubular member 18, and a coaxial socket formation 28 at the joint end of the female tubular member 16. The spigot formation 26 is received in spigot-socket fashion within the socket formation 28. The jointing arrangement 34 permits angular and rotational movement of the two tubular members 16, 18 relative to each other. The coupler 10 also includes a securing arrangement that is a collar member extending over the socket member for mechanically holding the two tubular members 16, 18 to each other so that they cannot be separated.
