Definitions
- This invention relates to radiant tube space heating appliances of the kind comprising a radiation tube or duct, commonly suspended overhead in the space to be heated, a fan or other pump for inducing flow of gases along the duct in use, and one or more fluid fuelled burner assemblies, typically gas fired and automatically controlled, for feeding hot gases into said flow. Radiant heat is emitted from the duct surface and this is commonly directed and concentrated, e.g. in a downward direction, by reflectors mounted adjacent to the duct. Said appliances are hereinafter referred to as "radiant tube heating appliances”.
- the object of the invention is to provide a radiant tube heating appliance which is reliable and efficient in operation, and which gives improved performance and output.
- a radiant tube heating appliance as hereinbefore defined including a burner assembly comprising a burner head extending from a control and fuel mixing unit of the assembly to project laterally inwardly of the radiation duct into the path of flow therethrough in use and defining a fuel mix passage leading to a burner mouth defined by a front wall of the head angled to face downstream of said path of flow whereby the mix is operatively discharged along said flow for combustion in the duct immediately downstream of the head; characterised in that the burner mouth is an elongated slot whose major dimension extends longitudinally of the head in its direction of projection into the duct and whose minor dimension lies widthwise of the head viewed in a plane normal to the axis of the flow path and with the overall width of the head within the duct being little greater than the width of said mouth so that obstruction to flow in the duct past the head is minimized.
- This arrangement has the effect of concentrating the flow of mix issuing from the mouth in use towards the distal end of the slot remote from the mixing unit so that more combustion takes place adjacent to a circumferential zone of the duct wall at the side opposite to said mixing unit to increase radiant heat output from that zone which will be operatively mounted to face e.g. downwardly or otherwise towards the parts of the space where most heat is required.
- said burner mouth will include a honeycomb or other matrix, e.g. formed from corrugated or other strip stainless steel or other metal, to prevent burning back into the head and smooth and further direct the outflow of mix therefrom.
- a honeycomb or other matrix e.g. formed from corrugated or other strip stainless steel or other metal
- the mixing unit includes connections for feeding gas fuel and combustion air to the fuel mix passage of the head which are positioned at or towards the rear and upstream facing wall thereof so that the inflows into the head for mixing therein are further concentrated in the direction of said distal end of the slot.
- the proportions of the slot forming the burner mouth will have a major dimension: minor dimension ratio of at least 2.8:1.
- the heating appliance may include a plurality of said burner assemblies spaced at intervals along a common radiation duct.
- Said assemblies may be disposed in series along a single duct length or may act in parallel in limbs of a branched duct and they may all be controlled in common or may have a degree of independent control dependent on requirements for the particular installation.
- the radiant tube space heating appliance of this example is an installation for heating a large space such as a factory building or public hall; the overall installation is generally conventional comprising branched runs of radiation duct being circular section tube 10 mounted overhead, e.g. near roof or ceiling level and provided with reflectors 12 for directing and concentrating the emitted radiant heat downwards in known manner.
- Hot gases provided by burner assemblies 14 at spaced intervals along each branch are drawn through the tube 10 by a common exhaust fan 16 leading to a discharge flue 18.
- Fan 16 is automatically controlled in known manner to maintain negative pressure in the system of tube 10 i.e. a degree of depression below the ambient atmosphere pressure and the gas flow in the various branches may be further regulated and balanced by manual or automatic dampers (not shown) in known manner.
- burner assemblies 14 will now be described in greater detail with reference to Figures 1-3. It comprises a fuel/air infeed and control unit 20 mounted externally on the upper periphery of tube 10 and a burner head 22 which projects downwardly into the tube as described in greater detail below.
- Unit 20 includes a box 24 defining an air chamber 26 which also serves as a protective enclosure for components of the unit, air being drawn into box 24 through a baffled air inlet 28 at one end.
- An air filter may also be provided.
- burner head 22 projects through a mounting plate 30 forming part of the floor of box 24 and which is secured to a flanged opening in the top of tube 10.
- the top of head 22 defines an air infeed opening 32 communicating directly with chamber 26 and which is off-centre, being positioned nearer to the rear wall 34 of head 22 than to its front wall 36 so that the air inflow is concentrated towards said rear wall.
- a gas fuel nozzle 38 also opens into the upper part of head 22 through the top of rear wall 34 and is connected to a gas fuel feed pipe 40 through a safety cut-off valve 42 and a gas pressure governor 44.
- the hollow interior of burner head 22 constitutes a fuel mix passage 46, the air and gas fuel inputs being proportioned so that a combustible mix is produced.
- the lower part of head 22 within tube 10 projects into the path of flow of gases induced along tube 10 from right to left as viewed in Figure 1 and the lower part of front wall 36 defines a rectangular burner mouth 48 on a diametral plane of tube 10 and angled to face downstream of the path of flow along tube 10.
- Mouth 48 is in the form of an elongated slot as best seen in the elevation of Figure 2, its height, i.e. extent lengthwise of front wall 36 being considerably greater than its width. Mouth 48 is centered in tube 10, and in this example its height is around two thirds of the tube diameter. The ratio of height to width of the mouth is preferably at least 2.8:1.
- the overall width of head 22 is only slightly greater than the width of mouth 48 but the depth between the front wall 36 and rear wall 34 is substantially greater.
- To provide streamlining rear wall 34 has only a short vertical section depending from plate 30 and is then angled to slope downwards at about 45 degrees towards the bottom of mouth 48.
- Said rear wall is also V shaped in horizontal section as shown in Figure 3 so that its exterior faces form an acute angle pointing upstream of the throughflow.
- Plate 30 also mounts a conventional electrical ignition device 52 for initiating combustion of the mix on start-up and a conventional flame sensing electrode 54 acting in conjunction with cut-off valve 42 to terminate the gas fuel supply in case of flame failure, these controls being associated with an electrical module 56 of the burner assembly in known manner.
- the burner head will operate at a negative pressure of at least 2 mba within its mix passage 46 and all the air required for combustion of the gas fuel is pre-mixed in said passage prior to discharge from mouth 48.
- the use of the honeycomb matrix 50 in the mouth also provides improvements in efficiency and performance in comparison with the multi-port ceramic burner mouth inserts used in some known appliances.
