Definitions

  • Embodiments of the present invention relate to a sealed air boiler air inlet chamber, a sealed air boiler including the air inlet chamber and a heating system including the sealed air boiler.
  • Commercial boilers may be used for large scale heating, and may be located in a specifically designated room, e.g. a plant room.
  • Air is required for the combustion of fuel (e.g. gas or oil) to produce heat energy.
  • fuel e.g. gas or oil
  • air may be admitted to a boiler from the surrounding environment (e.g. a plant room), for example, through an opening in the housing of the boiler.
  • boiler housings may be sealed to the surrounding environment (e.g. a plant room), and instead receive air through an inlet such as a ventilation shaft or other pipe.
  • a ventilation shaft or other pipe Such a pipe may be open to outdoor air. Government regulations or other factors may favour boilers that are sealed to the surrounding environment.
  • Such boilers may be known by various names, such as “sealed air boilers” or “room-sealed boilers”.
  • Outdoor air may be damp, i.e. contain water. Therefore, air entering a sealed air boiler from outdoors may contain a significant fraction of water. It may be advantageous for the air entering the furnace of a boiler to be relatively dry.
  • an inlet chamber for a sealed air boiler which may reduce the amount of water within the air which is fed to the furnace of the boiler.
  • a sealed air boiler air inlet chamber comprising a casing, defining a volume, an air and water inlet aperture, a first outlet for water, and a second outlet for air, and a barrier, spaced from the second outlet, demarking a first region of the casing including the first outlet and a second region of the casing including the second outlet, wherein the barrier may be configured to inhibit the flow of water from the first region to the second region and to permit the flow of air from the first region to the second region.
  • the barrier may extend a height from a plane of the casing including the second outlet.
  • the barrier may extend between a first surface and a second surface of the casing.
  • a surface of the casing may be inclined towards the first outlet in use.
  • the sealed air boiler air inlet chamber may further comprise a connector for connecting the first outlet to a drain.
  • the sealed air boiler air inlet chamber may further comprise a connector for connecting the second outlet to a furnace.
  • the first outlet and the second outlet may be of different sizes.
  • the first outlet may be smaller than the second outlet.
  • the sealed air boiler air inlet chamber may further comprise a spacer.
  • the spacer may be for inhibiting an object within the chamber from contacting a surface of the chamber.
  • the object may be an air inlet pipe.
  • the spacer may be for inhibiting an open end of the pipe from contacting a surface of the chamber, such that the pipe remains open.
  • the sealed air boiler air inlet chamber may further comprise a fixing for fitting the air inlet chamber to a sealed-air boiler.
  • the chamber may have an outer rim and the fixing may be located on the outer rim of the chamber.
  • the boiler may be a sealed air boiler.
  • thermoelectric heating system comprising a boiler as described above.
  • the heating system may be a central heating system and/or a water heating system.
  • a sealed air boiler (sometimes referred to as a room sealed boiler) draws in air for combustion from outside the space in which the boiler is located. Accordingly, the air drawn into the boiler may have different characteristics from the air in the space in which the boiler is located (for example, the air drawn into a sealed air boiler may be wetter than air in the immediate surrounds of the boiler).
  • boilers can function more effectively when the air used for combustion is drier, that is, not wet. It is therefore a first non-exclusive aim to provide a sealed air boiler air inlet chamber, which can separate water from combustion air.
  • a sealed air boiler air inlet chamber indicated generally at 1 comprises a casing, defining a volume, an air and water inlet aperture 101, a first outlet 3 for water, and a second outlet 4 for air.
  • the barrier 2 demarks a first region 30 of the casing which includes the first outlet 3 and a second region 40 of the casing which includes the second outlet 4.
  • the barrier 2 is configured to inhibit the flow of water from the first region 30 to the second region 40 and to permit the flow of air from the first region 30 to the second region 40.
  • Such a sealed air boiler air inlet chamber 1 may provide an advantageous high separation of water from feed air (e.g. outside air).
  • feed air e.g. outside air
  • water which may be present as a contaminate in the feed air will predominantly exit through the first outlet 3 in the first region 30 and air will predominantly exit through the second outlet 4 in the second region 40.
  • drier air may be provided to the furnace of a sealed air boiler.
  • the sealed air boiler air inlet chamber 1 may be used with a sealed air boiler which can still operate as a sealed air boiler even when the housing of the boiler is open, as will be described in more detail below.
  • the casing may include side surfaces and/or a base.
  • the side surfaces may be substantially vertical walls 10.
  • Surfaces 100 of the casing may be inclined with respect to the walls 10.
  • the walls 10 may include inclined portions 100.
  • the barrier 2 may extend a height from a plane of the casing including the second outlet 4. Such a construction may be particularly simple, and therefore economic.
  • the barrier 3 may extend between a first surface and a second surface of the casing.
  • the barrier 2 may contact a first surface and a second surface of the chamber 1.
  • the first surface may be a wall 10 or an inclined surface 100.
  • the second surface may be a wall 10 or an inclined surface 100.
  • the barrier may contact multiple walls 10.
  • the barrier may extend between opposite walls 10.
  • the barrier may contact multiple points on the same wall 10.
  • the barrier 2 may be a substantially straight barrier 2, as shown in Figs 1 to 4 .
  • the barrier 2 may define an angle.
  • the barrier 2 may extend between a first wall 10 and a second wall 10 that are substantially perpendicular to one another, such that the barrier 2 defines a right angle.
  • the barrier 2 may extend between a first wall 10 and a second wall 10 at any angle, e.g. any other angle.
  • the barrier 2 may extend between a first wall 10 and a second wall 10 where both walls 10 are on the same side of the casing.
  • the barrier 2 may extend a height that is generally level with the top of an inclined surface 100.
  • the barrier 2 may extend a height based on the expected volume of water that may enter the first region 30 of the casing in use. Additionally or alternatively, the barrier 2 may extend a height based on the efficiency with which water leaves the chamber 1 via the first outlet 3.
  • the barrier 2 may contact a base of the casing of the chamber 1 such that the contact is air-and-water-tight. Such contact may be achieved by any means apparent to the skilled person, for example, by welding the barrier 2 to the chamber 1. Alternatively, such contact may be achieved by forming the barrier 2 integrally with the chamber 1. Air-and-water-tight contacts between the barrier 2 and a wall 10 and/or a base of the casing of the chamber 1 may be achieved using any means apparent to the skilled person.
  • the barrier 2 may also be spaced from the first outlet 3.
  • the barrier as described above can provide a particularly distinct second region 40 for the second outlet 4, which in turn can be used to provide good separation of water from the air to be fed to the furnace of the boiler.
  • a surface of the casing may be inclined towards the first outlet 3 in use. Such inclined surfaces may contribute to the flow of water towards the first outlet 3 within the first region 30, thereby providing good or increased separation efficiency.
  • the first outlet 3 may be in a base of the chamber 1. However, the first outlet 3 may be defined in a wall 10 or inclined surface 100 of the chamber 1, within the first region 30 of the casing. For example, the first outlet 3 may be defined in a corner of the chamber 1.
  • the sealed air boiler air inlet chamber 1 may further comprise a connector 301 for connecting the first outlet 3 to a drain.
  • the first outlet 3 may be connected to a first connector 301 for connecting the chamber 1 to a pipe.
  • the first connector 301 may extend a length away from the surface defining the first outlet 3.
  • the first connector 301 may form part of the inner surface of the first outlet 3.
  • the first connector 301 may be integrally formed as part of the chamber 1, or may be otherwise attached to the chamber 1.
  • the first connector 301 may be continuous around the circumference of the first outlet 3.
  • the first connector 301 may be another type of connector, designed so as to mesh with the desired exhaust means, such as a pipe.
  • the first connector 301 may provide a water-tight connection between the chamber 1 and an exhaust means. As shown in Fig. 1 , the first connector 301 can be seen extending a vertical length from the casing 1.
  • the sealed air boiler air inlet chamber 1 may further comprise a second connector 401 for connecting the second outlet 4 to a furnace.
  • the second connector 401 may extend a length away from the surface defining the second outlet 4.
  • the second connector 401 may form part of the inner surface of the second outlet 4.
  • the second connector 401 may be integrally formed as part of the chamber 1, or may be otherwise attached to the chamber 1.
  • the second connector 401 may be continuous around the circumference of the second outlet 4, as shown in figure 1 .
  • the second connector 401 may be another type of connector, designed so as to mesh with the desired exhaust means, such as a pipe.
  • the second connector 401 can be seen extending a vertical length from the circumference of the second outlet 4.
  • the second connector 401 may extend a horizontal length away from the second outlet 4, and may extend along the outer surface of the chamber 1, in order to connect the chamber 1 to an exhaust means.
  • the second connector 401 may otherwise mate with the chamber 1.
  • the sealed air boiler air inlet chamber 1 may have a first outlet 3 and the second outlet 4 of different sizes.
  • the first outlet 3 may be smaller than the second outlet 4. This may be advantageous, as the volume of air passing through the inlet chamber 1 and out of the second outlet 4 will usually be much larger than the volume of water passing through the inlet chamber 1 and out of the first outlet 3.
  • the sealed air boiler air inlet chamber 1 may further comprise a spacer 5.
  • the function of the spacer 5 can be for inhibiting (e.g. for stopping or substantially preventing) an object within the chamber 1 from contacting the base of the casing.
  • the spacer 5 may be located within the first region 30 of the casing.
  • the spacer 5 can space an open end of an air (and water) inlet pipe, from the casing of the chamber 1, to inhibit (e.g. substantially prevent) the open end of such a pipe from contacting and therefore being closed off by contacting a surface of the chamber 1. Accordingly, the pipe may remain open.
  • multiple spacers 5 may be provided.
  • the spacer 5 may extend across a width of the chamber 1.
  • the chamber 1 may comprise a fixing 12 for fitting the air inlet chamber 1 to a sealed-air boiler. As shown in Figs 1 to 4 , the fixing 12 may be located on an outer rim 11 of the chamber.
  • the outer rim 11 may be continuous around the perimeter of the casing of the chamber 1, as shown in figures 1 to 4 . Additionally or alternatively, the outer rim 11 may be a continuation of the walls 10, e.g. the top of the walls 10 may be shaped to form the outer rim 11.
  • the outer rim 11 may define a plane which may be substantially perpendicular to that of the walls 10 of the chamber 1.
  • the fixing 12 may be a cut-out, for use with a further means of fixing the chamber 1 in place.
  • the cut-out may be of dimensions to fit a screw or another fixing.
  • the outer rim 11 may not define cut-outs 12 and may instead be designed to fit in any other way, as will be apparent to the skilled person.
  • the outer rim 11 may further include hooks or another type of fixing means.
  • rails or another receiving means for the chamber 1 may be positioned in a boiler to allow the chamber 1 to be fixed in place.
  • the chamber 1 may be fixed in place within a boiler using an adhesive, e.g. a sealing adhesive or a sealant.
  • an adhesive may be applied to the outer rim 11.
  • the chamber 1 may be removably fixable to a boiler, for example to facilitate servicing of the boiler including removal of the chamber 1.
  • a boiler 6 including an air-inlet chamber 1 as described above.
  • the boiler 6 may be a sealed air boiler 6.
  • Inclusion of the air inlet chamber 1 in a sealed air boiler 6, may be particularly advantageous as it can help to provide a sealed air boiler which is sealed both when the housing of the boiler is open (e.g. during adjustment) and whilst the housing of the boiler is closed (e.g. during normal use). Accordingly, a sealed air boiler 6 which is more easily correctly commissioned can be provided.
  • the chamber 1 may be positioned at the top of the boiler 6, as shown.
  • a surface of the boiler 6 may close-off a top of the chamber 1 that is open when not installed within the boiler 6.
  • the chamber 1 may be closed-off or contained in some other way, as would be apparent to the skilled person.
  • the chamber 1 is for use between the air and water inlet (for example the air and water inlet aperture 101) of a boiler 6 and the rest of the boiler system.
  • the boiler 6 may include an air and water inlet pipe.
  • the air and water inlet aperture 101 of the chamber 1 may receive an air and water inlet pipe in use. Accordingly, water may drip from the air and water inlet pipe. Any water admitted to the inlet chamber 1, is admitted in the first region 30 of the casing, accordingly, the water can exit the first outlet 3.
  • the air and water inlet aperture 101 should not open directly into the second region 40 of the casing, as the barrier 2 would not then be able to fulfil its function of substantially preventing or inhibiting water from entering the second region 40 of the casing and exiting the second outlet 4.
  • Air from the air and water inlet aperture 101 is passable over the barrier 2 into the second region 40 of the casing, such that air may exit the chamber 1 via the second outlet 4 and may be drawn beyond the chamber 1 further into the boiler 6 for combustion.
  • air is the useful part of the intake into the chamber 1 and may be drawn into the boiler 6 from the second outlet 4 in any suitable way.
  • the sealed air boiler air inlet chamber 1 can be suitable for use with any suitable suction means known in the art of boilers.
  • the term 'drawn' does not exclude the free flow of air into the boiler 6 without the use of any particular suction means or other means of inciting air flow.
  • a first pipe 302 is shown, which can connect the first outlet 3 of the chamber 1, for example using a first connector 301, to part of the boiler 6.
  • the first outlet 3 may be connected to a drain 303.
  • the drain 303 may be external to the boiler 6 such that the first pipe 302 traverses the boiler 6.
  • the drain 303 may be external to the boiler 6 such that water from the first outlet 3 does not interact with any other part of the interior of the boiler 6 except for the first pipe 302.
  • the drain 303 may otherwise be a drainage component inside the boiler 6 that includes a reservoir or a similar water collecting receptacle.
  • the drain 303 may be the same drain as is used for condensate from the boiler.
  • a second pipe 402 which connects the chamber 1 at the second outlet 4, by the second connector 401, to a further part of the boiler 6.
  • the second outlet 4 may be connected directly or indirectly to a furnace.
  • the second pipe 402 may have a diameter corresponding to that of the second outlet 4.
  • the second pipe 402 may be connected in an air-tight manner to the second outlet 4.
  • An air tight connection may be advantageous as it can allow the boiler to be air sealed even when a cover of the boiler is not in place.
  • the chamber 1 may be shaped to fit to the shape of part of the boiler 6.
  • a heating system 8 comprising a boiler 6 as described above, including the inlet 1 described above.
  • the heating system 8 may be a central heating system. Additionally or alternatively, the heating system 8 may be a water heating system.
  • the heating system 8 may comprise a heating element 7, which is in communication with the boiler 6.
  • the heating element 7 may be a wall-mounted radiator.
  • the heating element 7 may be a water heater.
  • a single heating system 8 may comprise multiple heating elements 7 and may comprise different types of heating elements 7.
  • the heating system 8 may include a single boiler 6.
