Definitions

  • This invention relates to gas burner assemblies, especially but not necessarily exclusively for use in boilers intended for domestic heating and/or hot water systems.
  • Different kinds of boiler are available and in use today. They include free standing boilers, wall hung boilers and back boiler units which are incorporated with gas fires, as well as other kinds.
  • a boiler it is usual for a boiler to include a gas burner assembly which comprises a burner, a control arrangement, and a manifold interconnecting the burner and the control arrangement for conducting gas to the burner from the control arrangement, the control arrangement including means to control the supply of gas to the burner.
  • a burner assembly of the form initially described In the prior art assemblies the manifold takes the form of a rigid pipe which is bent to the required shape, having regard to the desired relative positioning of the control arrangement and burner in the completed assembly, and this pipe is provided with the necessary drillings and tappings for the gas connections.
  • a mounting or flange plate is welded to the pipe at a position intermediate its ends and in the finished boiler this plate is located at the interface between respective compartments defined within the boiler casing.
  • the burners are made as complete prefabricated units dependent upon the particular design and kind of boiler as well as its heat output rating.
  • control arrangement is at least for the most part pre-assembled into a finished unit ready for incorporation into the burner assembly and made in accordance with the type of control with which the boiler is to be equipped.
  • an auxiliary pilot burner with its associated ignition device and pilot flame sensor probe (if provided), has to be mounted on or in the vicinity of the main burner, and the necessary gas and electrical connections have to be made with the control arrangement.
  • the present invention addresses the aforementioned problem and whereas the gas burner assembly specifically described hereinafter and illustrated in the accompanying drawing embodies several novel features each of significant benefit in itself, when incorporated together in a single embodiment these features combine to ensure great versatility in the basic design whereby the assembly can be adapted so as to be dedicated to a given boiler at only a late stage in the manufacturing process.
  • several boilers can be made having different burner assembles, but which assemblies share common basic components capable of being assembled together in different ways and adapted to receive further modules selected from a limited range in order to tailor the assembly according to the particular needs of that boiler into which it is to be fitted.
  • a gas burner assembly comprising a burner (1), a control arrangement (3) for controlling the gas flow to the burner, and a manifold (2) interconnecting the burner and control arrangement for conducting gas to the burner from the control arrangement,
  • the manifold (2) comprises a member defining a plurality of non-communicating conduits providing a main gas passage for conveying gas to the burner (1), and a further gas passage isolated from the main gas passage for conducting gas to a pilot burner (5), and that the manifold (2) has means for connecting the manifold to the burner and/or to the control arrangement in any selected one of a plurality of positions relative thereto.
  • the composite manifold eliminates the need for respective pipes connecting the main and pilot burners.
  • the manifold member can be conveniently made as an extrusion or as a casting. Additional channels, either open or closed, may be provided in the manifold member and serve as cable ducts for electrical wiring connected to a pilot ignition device and a pilot flame detector/monitor.
  • the manifold member comprises at one end a connection flange having openings which communicate with the respective gas passageways.
  • This connection flange is secured by suitable mechanical fastening means, such as a quick release coupling, to a face of the control arrangement body, which face has gas ports located therein to register with the gas openings of the flange.
  • the connection flange and the corresponding face of the control body are so arranged that the manifold member can be turned through 180° and the necessary gas connections are still maintained.
  • the connection flange may have two pilot gas openings located uniformly either side of the main gas opening so that one of the openings will register with the pilot gas port and the other opening will be sealed closed when the flange is fastened to the control body. It will be understood that this feature enables the control arrangement to be reversed, whereby the configuration of the burner assembly may be chosen to suit a given boiler.
  • the manifold member is secured to the burner, and the manifold member may carry a gas injector nozzle for delivering gas from the main manifold passage into a main burner inlet shroud which also acts to connect the burner to the manifold member.
  • the manifold member may be fitted with a pilot gas injector nozzle to deliver gas from the pilot gas passageway, e.g. into an air mixing tube leading to the pilot gas burner.
  • the burner is connected to the manifold by means permitting the angular disposition of the manifold with respect to a substantially horizontal axis determined by the burner to be selected.
  • the correct disposition of a gas burner is fixed and predetermined by the burner design.

  • the means connecting the burner to the manifold comprises a cylindrical part, so that the angle of the manifold may be selected to have any value within the range of 0 to 360°.
  • the connecting part is provided by an inlet shroud of the burner, in which case a main injector nozzle fitted to the manifold may be positioned to direct the jet of gas along the tube axis, which is coincident with and serves to define said substantially horizontal axis.
  • the manifold is also equipped with an injector for delivering gas to a pilot burner as mentioned above, a series of connection points for this injector may be included in the manifold at locations set by predetermined angular dispositions for the manifold, the injector being applied at the appropriate connection point when it has been decided which angular disposition the manifold is to take.
  • the attachment of the main gas inlet shroud to the manifold can be achieved by a suitable means which will enable the angular disposition of the manifold to be easily adjusted to that required and then firmly secured or locked to prevent undesirable subsequent relative movements.
  • control arrangement comprises a body, and at least one prefabricated and fully assembled valve module mounted on the body as a unit for controlling flow of gas through a passage formed in the body and connecting gas inlet and exit ports.
  • one valve module controls flow of gas from a gas inlet port of the body to a port which is connected to a pilot burner, and a second valve module controls flow of gas through a passage leading to a gas outlet port which is connected to the manifold for delivering gas to the main burner.
  • the valve modules are self-contained devices which can easily be secured to the body by a suitable mechanical connection or direct coupling and this assembly operation can be quickly and conveniently completed by unskilled personnel. Once fitted the valve modules can only be disassembled with the use of a tool.
  • the or each valve module is selected from a range of modules which may include, for example solenoid valves, modulation valves and manually operable, e.g. manual preset flame failure, valves.

  • Another module which can be carried on the body of the control arrangement is a spark generating device and once again the necessary electrical connections to this device may be made through the body with contacts being provided on the respective parts and arranged to be brought automatically into correct cooperation when the spark generator is mounted in position.
  • the appropriate modules can be selected and be readily attached to the body at any convenient stage in the boiler manufacturing process, whereby the arrangement is adapted to meet the requirements of the control programme for the particular boiler being made. No special skills are required, the modules being prefabricated as complete, self-contained units.
  • the body itself provides the necessary gas flow passages between the gas ports and the electrical connections between the electrical contacts, but it does not itself incorporate any of the control parts until it is equipped with selected modules.
  • the body could be modified to include a gas cock for isolating the valve modules and other parts of the burner assembly from the gas supply, e.g. during periods of maintenance.
  • valves capable of receiving different types of actuator for operating the valve.
