Definitions

  • Combustion devices for heating water in central-heating systems can nowadays be constructed very compactly, for instance for heating an apartment in a larger building. Such compact combustion devices can then be connected to for instance a collective supply conduit for supply of air and/or a collective discharge for discharge of combustion gases.
  • the present invention has for its object to obviate one or more of the above stated problems and provides a device for combusting fuel and oxidizing agent, for instance for space heating, wherein the device comprises:
  • the closing means When the burner is connected to a collective air conduit in the switched-off situation, the closing means prevent relatively cold air entering the interior thereof, which may reduce efficiency. In the case of connection to a collective discharge conduit for the combustion gases, the closing means prevent the possibility of combustion gases from another combustion device being drawn into the interior of the boiler, which is likewise undesirable.
  • the closing means are formed by a valve which can move freely up and downward between baffle-like members forming part of mixing means, it has further been found that the noise nuisance is prevented, probably because the resistance in the air path is increased.
  • the up and downward movable disc-like valve is preferably arranged with some clearance round a central shaft.
  • a device 10 On the underside of a device 10 air is supplied as according to arrow A via a fan 11, while the gas for combusting is supplied under some pressure via connection 12 as according to arrow B.
  • a mixing space 8 Arranged in a mixing space 8 are disc-shaped baffles 13, 14, 15 and 16, in which passage openings for the gas and the air are provided which are successively offset relative to each other for mixing the gas and the air in efficient manner, as indicated schematically by the arrows.
  • the mixture of air and gas is subsequently carried into the interior of burner 17 and burns in the annular space 18 to heat the helical pipe 19 which in the present case comprises an inner pipe 20 and an outer pipe 21.
  • the combustion gases are urged downward and discharged via a discharge conduit 22 for the combustion gases.
  • Inner pipe 20 and outer pipe 21 are connected to a central-heating system and the circuit for hot water, further details of which are described in the Netherlands patent application 1004410, the content of which must be deemed as interpolated herein.
  • Tap water for heating is fed for instance as according to arrow C and drained as according to arrow D
  • water for heating for the central-heating system is fed for instance as according to arrow E and drained as according to arrow F.
  • a substantially disc-shaped valve 30 is arranged between mixing baffles 14 and 15 for free movement with some clearance round a central shaft 31. If device 10 is switched off and combustion is stopped, fan 11 will also be switched off, whereby disc 30 drops due to its own weight onto disc 15 and closes the openings therein. The air path through the combustion device is hereby closed and relatively cold air and/or combustion gases are prevented from being able to enter the interior thereof.
