Definitions

  • the present invention relates to a fuel-heated heat source according to the preamble of the main claim.
  • Such fuel-heated heat sources have become known as so-called chimney-free circulating or continuous water heaters, which are used to feed a heating system and / or a domestic water heater.
  • a concentric pipe unit which penetrates an outer wall of the installation space of the heat source, is used for supply air and exhaust gas routing.
  • the present invention has for its object to find a control for the bypass flap of such a fuel-heated heat source, which causes an increase in efficiency in the partial load range in a simple technical manner.
  • the fuel-heated heat source has an outer housing 1, which in its interior 2 surrounds an inner housing 4 of a combustion chamber at a distance 3.
  • a gas burner (not shown) and a heat exchanger 5 are arranged within the combustion chamber.
  • the combustion chamber 4 forms an exhaust gas hood 6 which has an outlet opening 7 which is covered by a housing 8 of a fan 9 and which forms the inlet opening for the fan from the exhaust gas outlet opening of the combustion chamber 4.
  • An outlet opening of the fan is connected to an exhaust pipe 10 which passes through the outer housing 1 at the top.
  • the exhaust pipe 10 is concentrically surrounded by a fresh air pipe 11, the annular space 12 between the two serves as a fresh air supply pipe.
  • the annular space 12 is guided within the distance 3 to a fresh air chamber 13, in which two recesses 14 and 15 are arranged.
  • the recesses 14 and 15 can be closed by two flaps 16 and 17 which can be actuated by a common actuating device 18.
  • the actuating device for the two flaps is in opposite directions. When one flap is open to the maximum, the other is closed and vice versa. If one is half open, the other is half open.
  • the actuator 18 is on one Actuator, not shown, of a fuel / lutt ratio controller connected.
  • a throttle command for the flap 16 and an opening command for the flap 17 result in accordance with the partial power. If the power of the fan 9 remains unchanged, part of the fresh air flow now becomes bypassing the interior of the combustion chamber 4 and the heat exchanger 5 given directly to the opening 7 directly via the partially open recess 15. This air does not take part in the combustion and does not penetrate the heat exchanger.
  • a partial load air flow rate is thus assigned to the partial load gas flow rate of the burner, so that the combustion works with the maximum efficiency.
  • the fuel-stained heat source 101 shown in its entirety in FIG. 2 has an outer housing 102, which has a rear side 103 and a front side 104, the front side being covered by two doors 105 and 106 arranged one above the other.
  • a combustion chamber 108 Arranged in the interior 107 of the outer housing 102 is a combustion chamber 108 which is gas-tight towards the atmosphere and which is connected to the outside atmosphere only via a unit 109 which has a concentric tube.
  • the unit 109 has an internal exhaust gas discharge pipe 110 and an external supply air pipe 111, the actual supply air supply having an annular gap which extends between the inner casing of the outer pipe 111 and the outer casing of the inner pipe 110.
  • This supply air duct merges into a guide duct 112 which leads vertically downwards on the rear side of the combustion chamber 108 and which opens into the interior 115 of the combustion chamber on the underside 113 in the context of an inlet opening 114.
  • a heat exchanger 116 is arranged with a heating shaft 117 extending it toward the rear, the latter both forming the actual interior 115.
  • the heat exchanger 116 formed from copper passes through a pipe coil, not shown, which is also wound around the heating shaft 117 on the outside. A fluid to be heated flows through this pipe coil, for example the water from a heating system or sani hot domestic water to be heated.
  • an exhaust gas collection chamber 118 On which a fan 119 is arranged, which is driven by a motor 120.
  • the exhaust gas outlet of the blower 119 communicates with the interior of the inner tube 110.
  • a burner 21 is arranged on the underside 113 of the heating shaft 117 and is fed via a fuel supply line 122 from a gas or oil reservoir, which is not shown in any more detail.
  • Below the heating shaft which is covered by the upper door 105 together with the heat exchanger and the exhaust gas hood 118, there is a room 123 in which all measuring, regulating and control instruments of the heat source are accommodated. This space is essentially covered by door 106.
  • an expansion vessel 124 is arranged between the rear of the combustion chamber 108 and the rear wall 102 of the housing.
  • the rear partition wall 125 of the combustion chamber which also acts as a wall for the guide channel 112 and at the same time is the rear wall of the heating shaft, has a bypass opening 127 in its upper region 126, which is assigned a bypass flap 128.
  • the bypass opening 127 connects the beginning of the supply air duct 112 to the interior of the exhaust hood 113, accordingly short-circuits for the actual combustion chamber aar.
  • the guide channel 112 is connected in terms of flow to the annular space 129 between the two tubes 110 and 111.
  • the passage of the bypass opening 127 is perpendicular to the cross-section of the guide channel 112.
  • the two openings thus form an angle of 90 °.
  • the bypass flap 128 is designed as a double-arm lever, one lever arm 130 is assigned to the bypass opening 127, the other lever arm 131 to the passage cross section of the guide channel 112.
  • the two arms can form a common part which is movable about a pivot axis 132 which is in the region of the rear wall 125 is mounted.
  • the two arms 130 and 131 preferably form an obtuse angle.
  • This angle is accordingly greater than the angle between the bypass opening and the vertical duct cross section of the guide duct 112. If the bypass flap is formed by two different flap elements, which are mounted to one another and to the housing of the heat source in the context of the axis 132, a spacer 133 is provided which attacks in eyelets 134 and 135 on both flap parts.
  • the shaft 132 and the bearing of the two flap elements 136 and 137 which are synonymous with arms 130 and 131, respectively, can be seen in FIG.
  • the two flap elements 136 and 137 are provided with teeth, the remaining webs being looped around the axis 132, in each case in the recess of the other flap element.
  • the eyelet 135 and the bracket 133 are clearly visible.
  • the holder 133 is a curved wire, in which a punched-out tab 135 is suspended.
  • a return spring 138 is suspended on one of the two arms 130 or 131 of the exhaust flap, the abutment 139 of which is arranged on the rear wall 103.
  • the return spring engages the lever arm 130, specifically at the point 137 at which a rope 140 is likewise fastened.
  • the cable 140 is guided and deflected over two rollers 141 and 142, these two rollers having axles fixed to the housing.
  • the axis of the roller 14ü lies on a sheet metal bracket 143 on which a further roller 144 is rotatably mounted with its axis.
  • the adjusting travel 156 is limited by the adjusting element 156 in accordance with the partial load of the heat source.
  • the ratio of the actuator can be changed in relation to the angle of rotation of the flap. It is thus possible to achieve large swivel angles of the bypass flap 128 even with small adjustment paths only available on the actuator 155.
