Abstract:
The improved inshot burner cluster apparatus of the present invention functions to provide combustion of a gaseous fuel and air mixture which is injected through an aperture in the inlet plate into the combustion compartment of a heat exchanger, and includes a burner cluster which may have a selected multiplicity of burners formed from an interjoined upper half shell and a lower half shell. The modular, and essentially clam-shell, form of construction allows for ease of forming the burner elements by embossing the sheet metal half shells, for example using a progressive type of punch press die which can thereafter cut-off any number of burners to form a burner cluster.
Abstract:
Gas injection pipe for a sequential burner in gas variable-power boilers. An array of gas injectors which are located on the injection pipe may each be plugged by a corresponding valve which is mounted on the free end of a rigid blade transversely extending through an internal chamber of the injection pipe. A rotating shaft which is stepwise driven is provided at right angles to each blade with recesses which are angularly offset on the shaft. Each blade is provided with a stud which is located in a corresponding recess when the latter is in its upward position. The stud lifts up the blade when the shaft is rotated on purpose to open the valve.
Abstract:
A handy torch comprises a tank, a first valve mechanism, a second valve mechanism, a burner having a nozzle and an air-intake opening. A pipe connects the second valve mechanism with the burner. The first valve mechanism includes a first valve body having a cylindrical inner wall with a female thread and a valve seat, an actuating member having a male thread screwed with the female thread of the first valve body, a disc, a resilient O-ring disposed between the valve seat and the disc. The O-ring is designed such that the gas flowing from an entrance of the first valve mechanism can be controlled by the O-ring in cooperation with the disc and the valve seat. A suction material connects the male thread of the actuating member with the gas in the tank. The second valve mechanism includes a second valve body having a passage and a through-hole with a female thread, and a needle having a male thread screwed with the female thread of the second valve body for controlling the gas flowing through the passage. A gas adjusting dial member is fixed to the needle. The torch comprises further a piezo-electric unit having an ignition button, an air adjuster and an air control lever. A casing houses therein at least partly the tank and others and has a gripped portion. The gas adjusting dial member, the air control lever and the ignition button are arranged near the gripped portion. The nozzle is inclined outwardly at an angle of 30-75 degree in respect to the longitudinal direction of the torch.
Abstract:
A dual gas supply blow torch has two gas inlets and a gas outlet for connection to a nozzle; a mixing and control valve operated by a single control device is interposed between the inlets and the outlet and this comprises a core axially displaceable in a bore provided with valve seatings. For each gas inlet the core has a valve formed by an annular elastic sealing joint engageable with a corresponding seating, and an escape passage is provided having a cross-section which can be varied by elastic deformation of the sealing joint in order to control the gas flow. At least one of the two valves has means for proportioning the gas flow rates.
Abstract:
An improved burner assembly for a water heater includes a gas supply tube with a uniquely constructed end portion for mounting the burner support bracket and burner. The end portion is partially flattened on its top surface and includes an attached gas discharge orifice. The burner supply bracket is attached directly to the end portion or is otherwise supported on the end portion so that gas passing through the discharge orifice appropriately mixes with air for combustion by the burner supported by the bracket.
Abstract:
The following specification describes a plural chamber gas cooking grill burner formed of two sheet metal shells with external reinforcing rods extending between the chambers and removably supporting the burner in a grill.
Abstract:
A high capacity, quiet burner for a hot air heating system for use in heating the top and bottom ends of a plastic coated carton, or the like, and which has a tubular burner body provided with a chamber therein which is open at an outlet end and enclosed at an inlet end. A burner nozzle is mounted in the burner body chamber adjacent the inlet end, and a mixture of primary air and fuel is conveyed into the burner nozzle and ignited by a spark plug. Secondary air under pressure is conveyed into the burner body chamber, for flow around the burner nozzle for heating the secondary air and for mixing the secondary air with combustion gases formed by the combustion of the mixture of primary air and fuel in the burner nozzle, and for subsequent discharge through the outlet end of the burner body chamber onto a carton end to be heated. The burner nozzle is provided with a screen pack for dividing the primary air and gas mixture into fine segments, and with a fiberglass filter means for reducing fluid flow noises. A perforated plate is also provided in the burner nozzle, and it co-acts with the screen pack for further reducing the noise level during the combustion process, as well as aiding in a uniform and stable combustion.
Abstract:
Cooperating die structure is disclosed for making the inlet end of a tubular burner construction. The inlet end is shaped by using a pair of dies which form a pair of spaced gripping parts respectively interconnected together at opposed ends thereof by substantially C-shaped resilient parts.
Abstract:
The gas welding and cutting torch comprises an elongated handle having a handle body. The handle body contains axially directed bores which are coupled to a gas supply by means of replaceable conduit pieces. The outlet end of each conduit piece that projects into the bore is shaped into a valve seat and is controlled by a conical sealing disc. The sealing disc is seated in a cage which is integral with a guiding member of a movable valve stem. The valve stem is arranged for axial movement within the bore; the guiding member of the valve stem has a threaded peripheral portion which is in engagement with a coaxially arranged hand control ring. The hand control ring is disposed in a recess intersecting the bore, and drives the valve stem and thus the sealing disc back and forth against the valve seat. The valve stem is provided with a central longitudinal passage for passing through the gas from the valve seat to a replaceable welding nozzle. The guiding member of the valve stem is sealed at each side of the recess and is spring loaded to avoid the backlash in the driving thread.
