  • the heater, or boiler is shown generally at 3, being rectilinear, having a flat top 4. Front, back and side louvre openings are provided as will be described. Numeral 5 designates a peripheral air intake opening which will be referred to more in detail presently.
  • Numeral l0 designates a combustion chamber having sidewalls 12 of typical heat and flame resistant material supported in the support frame or members 14. At the lower part of the combustion chamber are the burners l6, and this may be typically a gas burner, connected to a gas manifold 20. The base of the heating unit or appliance is designated at 22. A shield or jacket is provided around the combustion zone as designated at 26, it having louvres as shown at 28 and 30 for admission of combustion air.
  • the water heating unit comprising tube bundle 31.
  • ajacket or shroud 34 Surrounding the combustion chamber, flue products collector 32, and water heating unit is ajacket or shroud 34, which is spaced outwardly as shown from the combustion zone and flue product area.
  • louvre openings 36 and 38 In the sides of this jacket, spaced downwardly from the upper part thereof are louvre openings 36 and 38. Similar louvre openings 40 and 42 are provided at the front and back at the same level.
  • the jacket 34 extends upwardly to a point above the tube bundle 31 to an intermediate point relative to the flue product area 32, which is above the tube bundle or water heating unit 31.
  • louvred openings 52 and 54 In the sides of the jacket 34 toward the upper part of the wall are additional louvred openings 52 and 54 and similar louvred openings 56 and 58 are provided in the front and back ofthejacket.
  • the heater unit or appliance has a top 4 as referred to which is flat as shown.
  • a sidewall or baffle structure 66 Above the tube bundle 31 and combustion chamber sides 12 is a sidewall or baffle structure 66, the top edges of which are spaced below the top 4. These walls enclose the flue product area 32 and provide for the flue product outlet 68 adjacent to the flat top 4.
  • the walls taper inwardly, as designated at 70, completely around the upper part of the appliance and there is a collar or baffle 72, preferably comprising spaced vertical walls 72a, 72b, and 720, for a purpose which will be described more in detail presently.
  • the lower edge of the collar 72 is below the level of the upper edges of the inwardly tapering surfaces 70 ofjacket 34.
  • the outside of this collar preferably is flush with the outside of the jacket 34, and the upper edge of this collar is spaced from the periphery of the top 4 as shown.
  • a baffle 76 Adjacent to the top edge of the tapering surface 70 is a baffle 76 that extends out from the flue product chamber wall 66 and depends downward to a position adjacent to but spaced from the top edge of the tapering surface 70. It will be observed that the collar 72 forms a peripheral opening between itself and the top 4 which is an outlet opening of the flue products, as designated at 78. The space between the bottom of the collar 72 and the tapering surface 70 provides an opening which is the opening 5, FIG. 1. The space between the tapering surface 70 and the baffle 76 provides an air opening at 82 and the space between baffle 76 and the collar 72 provides an air opening 84. Collar 72 prevents direct effect of wind velocity on openings 5 and 78. It may be extended further downward to a position below opening 5.
  • insulation may be used in this element to further contribute to the desired effect of limiting temperature, although it is preferred to utilize the construction shown in which the horizontal dimension of the structure is lessened.
  • FIG. 4 illustrates the airflow and the operation of the unit under conditions oflimited wind of, for example, l miles per hour. It should be realized that it is necessary that the flue products can be evacuated from, that is, expelled from the unit under all conditions of wind. As shown in FIG. 4, with the wind coming from the right, the air enters through the opening 5 and is diverted by the baffle 76 and the enclosing wall 66, so that part of it now tends to flow downwardly within the jacket 34, to produce a limited forced draft sufiicient to insure that the flue products will be expelled from the flue product area. As will be observed in FIG. 4, with the wind coming from the right some air discharges from openings 52 and 36 on the opposite side. Discharge of flue products is mainly from opening 78 at the opposite or leeward side but nevertheless the unit is maintained at a desired exterior temperature.
  • FIG. 5 illustrates the flows under high-wind conditions.
  • the combustion air inlet opening must be considerably larger than the flue product opening to insure that the wind that enters through the combustion air opening will drive the flue products out of the unit against the prevailing wind. This has resulted in an appliance that was extremely high, and the openings presented an unsightly appearance. Further the openings often must be covered with expanded metal or wire mesh to prevent birds from building nests in these areas. This reduces the net area and makes the problem more complex and detracts from the appearance. In these conventional structures the large openings allow the unit to be susceptible to variations of wind velocity. All of these drawbacks are overcome in the herein invention and advantages are gained as will become apparent.
  • the louvres perform an additional function. Some of the air entering through the opening 5 is diverted downwardly as previously described in connection with the operation at limited wind condition. Under high wind the louvre openings 36 through 40 and 52 through 56 divert some of the entering air into a vertical direction. This upward flow of air tends to counter some of the downward flowing air through the upper opening 5 and this prevents an abnormal amount of airflow delivered to the burner while still maintain ing a balance between entering air and flue product discharge so that it is insured that the flue products are evacuated from the flue product area.
  • FIG. 6 shows a modified form of the invention which does not have the opening 82 between the tapered surface 70 and bafile 76.
  • Extending upwardly from the inner edge of baffle 70 is a continuous upright baffle member 57.
  • Wind entering through the upper opening 5 now moves upwardly between the baffle member 57 and the inner baffle member 72a forming a nozzle or venturi effect which produces a negative pressure on the inboard or inward side of the baffle member 57 which serves to evacuate the flue products from the flue product area and to discharge them through the opening 78.
  • combustion air is provided through the louvre openings 36 through 40 and 52 through 58 and forced draft such as described in connection with FIGS. 4 and 5 is created by means of the nozzle or venturi as described to insure that the flue products are expelled from the flue product area and evacuated from the appliance.
  • FIGS. 7 and 8 are partial detail views showing the structure at the upper end of the appliance. Battling is provided to prevent driving rain from entering the unit and having access to the flue product area or to the jacket area. It will be noted that at the upper end of the wall 720 there is an inwardly tapered surface I00. In the opening 78 surrounding the top 4 are provided the vertical baffle members 102 and 104. Posi tioned in the flue product area or zone is a splitter baffle I06 which is above the upper edge of the flue product area wall 66 as shown. An outwardly depending flange or lip 108 is provided at the upper edge of the wall 66. Depending from the lower edge of the top wall 4 around its periphery is a flange or lip 109.
  • This baffling arrangement is such that even in a driving rain the water cannot gain access to the flue product area or the area within the jacket 34. This result is illustrated by the geometry of the baffling arrangement made clear by the lines through 128, FIG. 8. These lines demonstrate that downcoming rain, whether coming straight down, or at any angle to the baffles I02 and 104 will strike baffle surfaces so that it is deflected from the flue product area and the area within the jacket 34. As can be observed, any rainfall coming straight down will be deflected by the baffle surface 76.
  • baffles I02 and I04 or lip 109 so as to be further deflected by baffle I06, vertical wall 66, baffle 76 or bafile member 720.
  • the lip 109 forms a drip lip so that water dripping from the top members 4 is prevented from dripping into the flue product area.
  • FIGS. 9 and 10 show a modified form of the invention wherein the upper or outer collar is supported by brackets which are combined collar supports or support brackets, and cooling air ducts, i.e., the brackets themselves form cooling air ducts as will be described.
  • FIG. 9 is a cross-sectional view showing one of the support brackets in position supporting the collar and
  • FIG. 10 is a perspective view of one of the brackets. The combined bracket and cooling air duct shown in FIG. 10
  • the bracket 140 is designated generally by the numeral 140, the collar being designated at 142.
  • the collar may be supported by eight of the brackets 140 for example, two on the front, back, and on each side of the unit.
  • the outer face or edge 144 of the bracket is rectangular as shown having extending mounting flanges 146 and 148 by which baffle member 142a may be attached by screws as shown in FIG. 9.
  • the bracket member 140 has an inner part which tapers to become deeper as designated at 150.
  • the bracket has a top 152 and a top opening 154.
  • the bracket has a vertical inner side as may be seen at 156 in FIG. 9 and another tapered or slanting surface 158 as may be seen in FIG. 9.
  • the combined bracket and duct is installed as shown in FIG. 9 with the slanted surface 158 juxtaposed 70 and attached thereto and with the vertithe upper bent over edge of the enclosing wall 66 as shown.
  • FIG. 9 The airflows and flows of products of combustion are as shown in FIG. 9. Referring to the air that can enter through the opening 5, some of this air can pass between the brackets I40 and it can enter into the space within the jacket 34 as shown in FIG. 9. Part of this air can pass through the interior of the duct forming brackets 140 as shown by the arrows and it can pass up through the openings 154 into a space between double walls 160 and 162 and then it can pas out of a stack 164. Thus this air serves to cool the top ofthe unit.
  • Part of the air coming in through opening 5 can also pass up between the baffle members 142a and 14212 for assisting in keeping the upper part ofthe unit cool.
  • the flue products from the area 32 can pass between the air duct brackets 40 as shown by the arrows and then can pass out through the opening 78 between baffles I02 and I04 as previously described. Some of the air entering through the opening 5 as will be observed, as in previous embodiments, can mix with flue products to dilute them and cool them as they pass upwardly and out through the opening 78.
  • a heating appliance having a combustion chamber, a flue products chamber and fluid heating unit, the appliance having first means including an appliance providing of said first openings of said air mixes with imperforate top portion of said passageways connecting at least some and said other openings whereby some and dilutes said flue products.
  • a heating appliance having a combustion chamber, a flue products chamber and fluid heating unit, the appliance having first openings near the upper part thereoffor admitting air into the appliance and having other openings near the upper part thereof for discharge of flue products and passageways connecting at least some of said first openings and said other openings whereby some of said air mixes with and dilutes said flue products, an air jacket on said appliance and passageways for admitting combustion air into saidjacket, through said first openings, and openings positioned at the lower part of said jacket for admitting air thereto, whereby convection air rises in the jacket and mixes with enterin air and flu e products.
