Definitions

  • the present invention relates to an enclosed boiler and in particular to an enclosed boiler of the type comprising:
  • the present invention is directed towards providing an improved construction of such boiler and in particular to an improved heat exchanger means for such a boiler.
  • baffle plates ensures that a very high thermal efficiency is obtained in the boiler.
  • the core is substantially equi-spaced from the sidewall means. This has the advantage of ensuring that the heat transfer around the boiler is as constant as possible.
  • the core is rectangular in cross-section. This has the advantage of ensuring that with a rectangular section boiler, as is common, the core mirrors the interior surface of the boiler such that the space between is of substantially constant cross-section, except at the four corners.
  • the combustion gas outlet communicates with the flue gas outlet via the core. This is a particularly efficient way of ensuring that you can have an equal number of passageways and permits the leading of the combustion gases through effectively 360° around the core.
  • the flue gas passageways communicating with the hot gas inlet and the flue gas outlet are opposite each other on either side of the core such that as flue gases are led around the flue through substantially 180°. While this doesn't allow quite the same length of travel around the core, it has the advantage of scavenging the boiler quicker.
  • the core is in the form of a cylinder.
  • the enclosure of the boiler should be circular in cross-section such a construction would be advantageous.
  • the bottom plate has an opening communicating with the interior of the core and an opening communicating with a passageway to form the combustion gas inlet and in which the top plate seals the core and has an opening communicating with a passageway to form the combustion gas outlet.
  • At least one of the transverse passageways sealing the core is a hollow wall for carrying hot water to be heated.
  • the heat exchanger means forms a plurality of interconnecting parts for ease of removal. It will be appreciated that manufacturing the heat exchanger in a number of parts will facilitate removal in that the accessway provided can be smaller than is necessary if the heat exchanger is manufactured as one composite piece.
  • the core includes hollow walls arranged for carrying hot water to be heated. This further increases the heat transfer.
  • the cross-sectional area of the core is between 20% and 50% of the enclosure cross-sectional area.
  • the cross-sectional area of the passageway is greater than or equal to the cross-sectional of the transfer opening.
  • the boiler 1 is of generally rectangular shape in cross-section and comprises a base 2, a top 3 and sidewall means extending between the base 2 and top 3.
  • the sidewalls means are water carrying sidewall tanks and comprise a rear front and side portions formed from a main rear tank 4, a main front tank 5 and a pair of main side tanks 6 and 7 respectively.
  • These define an enclosure within which is mounted a heat exchanger means indicated generally by the reference numeral 10 through which flame and hot gases are led from a hot gas inlet supplied by an oil burner 12 to a flue gas outlet 13 feeding an exhaust gas flue 15.
  • Water is circulated through the tanks 4, 5, 6 and 7 by a water circulating pump from a water inlet to a water outlet all of which is not shown. Typically these would feed a hot water central heating system.
  • the top 3 has an accessway 16 with a removable cover 17 through which access is gained for the maintenance and cleaning of the boiler as will be described below.
  • the heat exchanger means 10 which is illustrated in more detail in Fig. 2 comprises a removable top plate 20 forming an upper transverse baffle plate and a bottom plate 21 forming a lower transverse baffle plate.
  • Four rectangular core plates 22 forming a core 23 are mounted on the bottom plate 21.
  • a plurality of rectangular plates 24 forming baffle plates extend outwardly from the core 23.
  • the plates 24 and the various tanks 4, 5, 6 and 7 define with the core 23 gas passageways.
  • the gas passageways are identified by the reference letter U for gas passageways in which the gas rises and by the reference letter D for gas passageways within which the gas falls and by various numerals to distinguish the various gas passageways U and D from each other.
  • any gas passageway which forms the entrance to the heat exchanger means 10 is identified by the letters ENT and the reference letter D or U as appropriate and similarly the gas passageway forming the last passageway before the hot gases exit the heat exchanger means 10 is identified by the additional letters EX.
  • Each plate 24 is connected to either the top plate 20 or the bottom plate 21 and is spaced apart from at least one of them, such that a transverse opening 25 is provided by a gap between the transverse edge of the plate 24 forming the upright baffle plate and the top plate 20, or the bottom plate 21.
  • the bottom plate 21 has an opening 26 communicating with the interior of the core 23 and an opening 27 communicating with the passageway UEN (see Fig. 4) to form a combustion gas inlet.
  • the top plate 20 seals the core 23 and has an opening 28 communicating with the passageway UEX to form a combustion gas outlet which as can be seen from Fig. 1 communicates with a space above the top plate 20 and beneath the top 3.
  • the burner 12 delivers flame through the hot gas inlet 11 beneath the bottom plate 21 and up through opening 27 into the passageway UEN and across into the passageway D1 through the opening 25 in the plate 24 between the passageway UEN and the passageway D1.
  • the hot gases are delivered down the passageway D1 to the bottom of the passageway D1 to the opening 25 where they enter the passageway U1 as can be seen from Fig. 5. From thence the hot gases pass up the passageway U1 through the opening 25 into the passageway D2 and down the passageway D2. They are then delivered out the passageway D2 through the opening 25 into the passageway UEX and out the heat exchanger means 10 through the opening 28.
  • hot gases are delivered up the passageway UEN into the passageway D3 and hence from the passageway D3 to the passageway U2 to D4 and again then to UEX.
  • the gases have thus split around the core 23 and have traveled up and down the main rear tank 4, the main front tank 5 and the side tanks 6 and 7.
  • Figs. 6 to 9 inclusive there is illustrated an alternative construction of boiler indicated generally by the reference numeral 30 in which parts similar to those described with reference to the previous drawings are identified by the same reference numerals.
  • the flue gases are carried the whole way around the core 23.
  • the hot gases enter through the passageway UENT and then proceed down the passageway D1 up the passageway U1 down the passageway D2 and alternatively up and down the passageways D1 to D5 and from D5 they are delivered into the passageway UEXT where they are delivered out the flue.
  • the advantage of this arrangement is that the gas has now been led effectively round 360° rather than 180° of the embodiment of Figs. 1 to 5 inclusive.
  • FIGs. 10 and 11 there is illustrated an alternative construction of boiler indicated generally by the reference numeral 40 and again parts similar to those described with reference to the previous drawings are identified by the same reference numerals.
  • FIG. 12 there is illustrated in plan view another arrangement of boiler indicated generally by the reference numeral 50 and again parts similar to those described with reference to the previous drawings are identified by the same reference numerals. The operation can be readily easily seen and doesn't require any further explanation.
  • FIG. 13 illustrates a still further construction of boiler indicated generally by the reference numeral 60 again in which the gases are led through almost 360°.
  • FIG. 14 there is illustrated a still further construction of boiler indicated generally by the reference numeral 70 and again parts similar to those described with reference to the previous drawings are identified by the same reference numerals.
  • FIGs. 15 and 16 there is illustrated a still further construction of boiler indicated generally by the reference numeral 80 in which parts similar to those described with reference to the previous drawings are identified by the same reference numerals.
  • a heat exchanger means indicated generally by the reference numeral 81 having a cylinder like core 82 and a plurality of radially arranged upright baffle plates 83 and 84.
  • the plate 84 extends between the top and bottom transverse baffle plates.
  • FIG. 17 there is illustrated a still further construction of boiler indicated generally by the reference numeral 90 again parts which are similar to those described with reference to the previous drawings are identified by the same reference numerals.
  • an inner core 91 in the form of a water carrying tank against which are mounted a plurality of baffle plates 92.
  • the baffle plates 92 cannot in this embodiment be affixed permanently to the core 91, but will preferably be mounted thereon by, for example, being slotted into grooves or the like on the outer surface thereof.
  • FIG. 18 to 20 there is illustrated a still further construction of boiler indicated generally by the reference numeral 100, again parts similar to those described with reference to the previous drawings are identified by the same reference numerals.
  • all the passageways are the same size and the bottom of the core 23 is sealed by the bottom plate 21 and the exhaust gases are delivered from the passageway UEN right through to the passageway U5 and from the passageway U5 to the top of the passageway DEX where they are delivered down the passageway DEX through an opening 101 into the core 23 of the boiler and through an opening 102 in the top plate 20 to the gas flue 15.
  • FIG. 21 to 24 inclusive there is illustrated an alternative construction of wall mounted boiler indicated generally by the reference numeral 110, in this embodiment parts similar to those described with reference to the previous drawings are identified by the same reference numerals.
  • the oil burner 12 is mounted below the base 2 and the front tank 5 contains an accessway having a removable cover 111 to allow access into the enclosure.
  • the heat exchanger means 112 comprises a top plate formed from a hollow water carrying top wall 113 which is connected to the main side tank 6.
  • the heat exchanger means 112 is also provided with a bottom plate 114 communicating through an opening 115 with a hollow cylindrical core 116 from which project radially outwards four equi-spaced rectangular plates 117 and 118.
  • the plates 117 are again provided with openings 25, however, it will be noted that the plate 118 connects between both the top wall 113 and the bottom plate 114 forming the lower transverse baffle plate.
  • the core 116 is provided with an opening 119 adjacent the top wall 113. The core 116 effectively forms the entrance passageway and feeds through the opening 119 into the passageway D1 as is shown clearly in Figs. 22 and 24.
  • FIG. 25 there is illustrated in a view similar to Fig. 24 an alternative construction of wall hung boiler indicated generally by the reference numeral 120 in which parts similar to those described with reference to the previous drawings are identified by the same reference numerals.
  • This boiler 120 is essentially identical to the boiler illustrated in Figs. 22 to 24 inclusive, except that instead of a cylindrical core, there is provided a rectangular core 121.
  • the cross-sectional area of the core is between 20 and 50% of the enclosure cross-sectional area. This ensures that most of the hot gases are directed against the boiler walls and not carried out the boiler without adequate heat transfer having occurred.
  • the cross-sectional area of the passageway is greater than or equal to the cross-sectional area of the transfer opening. This has been found to provide sufficient slowing down of the gases to ensure that sufficient time is taken for the hot gases in the boiler to ensure adequate heat transfer.
