Definitions

  • the present invention relates to a heating boiler with high autonomy of feeding with solid fuel.
  • Another object of the present invention is to provide a boiler which can be fed with solid fuel in large pieces, particularly wood in the form of logs whose cost is relatively low.
  • a further object of the invention is to provide a heating boiler which has the above-mentioned advantages and in addition can be fed, if desired, with liquid or gaseous fuel.
  • a heating boiler characterized in that it comprises a combustion chamber for solid fuel, provided with oblique side walls. converging downwardly on a grid for the fuel, and with at least one upper aperture for charging the fuel, said upper aperture being arranged adjacent said oblique side walls, a cylindrical body being arranged horizontally in the centre of said combustion chamber, said cylindrical body containing the heated fluid and being traversed by flue pipes opening into a discharge conduit.
  • a further combustion chamber for liquid or gaseous fuel is axially provided in the cylindrical body containing the heated fluid, said liquid or gaseous fuel being delivered by a burner secured to the front door of the boiler.
  • the boiler comprises a front wall 1, a rear wall 3 and two side walls 2, 4 having the basic characteristic of being oblique and converging downwardly towards the centre on a bottom grid 5.
  • the rear wall 6 of the boiler is provided with two longitudinal apertures 7 and 8 which are closed by pivotally mounted covers 9, 10.
  • the above-mentioned elements together form the combustion chamber 20 for solid fuel of the boiler.
  • a cylindrical body 14 containing the heated fluid is arranged in the centre of the combustion chamber 20 and is secured rearwardly directly to the wall 3 of the boiler and forwardly is spaced from the wall 1 to which is connected by brackets 15, 15'.
  • the combustion chamber for the liquid or gaseous fuel delivered by a burner 17 is provided in an axial recess 16 of the cylindrical body 14.
  • the cylindrical body 14 further comprises a bundle of flue pipes 18, 18', 18", etc., opening rearwardly into a chamber 19 communicating with the discarge conduit 21.
  • the fluid to be heated for example water 37, is fed to the body 14 through a conduit 22 and is removed through the conduit 23 to be conducted to radiators or other heating bodies, not shown.
  • the burner 17 is mounted in a hole of a door 24 adapted to close a capacious inspection and cleaning aperture provided in the front wall 1 of the boiler.
  • the assembly 25 for emitting the fuel and forming the flame of the burner 17 is received in a deflector 26 having a flange 27 arranged coaxially in front of the axial recess 16 of the body 14, but anchored at a slight distance therefrom for reasons which will be explained hereinafter.
  • the walls 1, 2, 3, 4 and 6 of the combustion chamber are appropriately insulated on the outside by insulating material 28 and inwardly are coated with refractory material 29 as is known in the art.
  • the refractory material can be replaced by an hollow space containing water connected to the fluid to be heated.
  • An aperture 30 closed in an adjustable manner by a door 31 is made in the lower area of the rear wall 3 adjacent the ash collecting chamber 11 to provide access for the air necessary for burning the solid fuel. Further, openings 32, 32 t for controlling the combustion are provided in the front door 24.
  • the burner 17 for liquid or gaseous fuel and the associated combustion chamber formed by the recess 16 is intended to be used in case of lack of solid fuel or in case it is temporarily exhausted for failure to introduce fresh fuel.
  • the boiler may be provided with known means adapted to detect any potential decrease in temperature of the heated fluid and to control the consequent starting of the burner 17 to restore the predetermined temperature of operation, as well as the usual adjustment and safety devices known in the art.
  • an additional discharge mouth 38 is provided which is connected to the chimney and is provided with an exhaust fan, not shown, which can be switched on when the covers 9, 10 are opened for the introduction of fuel to avoid the escape of smoke into the boiler room.
  • FIGs. 3 and 4 Another embodiment of the boiler for heating according to the invention is illustrated in Figs. 3 and 4.
  • This embodiment differs from the one described previously in that it is designed to be fed only with solid fuel and in that means are provided to permit the use of solid fuel of small size while still ensuring a high autonomy of feeding.
  • the cylindrical body 114 containing the heated fluid 137 is provided with a bundle of flue pipes 118, but does not contain any inner combustion chamber. With the same dimensions, the body 114 can therefore occupy a smaller space in the interior of the combustion chamber with the consequent possibility of charging a greater amount of fuel.
  • Two U-shaped structural bars 40, 41 are secured parallel to the axis of the cylinder to the lower cylindrical surface of the body 114.
  • Removably inserted in the groove of the U's are two C-shaped supporting elements 43, 44 of sturdy metal sheet provided with upper extensions 45, 46 adapted to be inserted in the U-shaped structural bars 40, 41.
  • the above-mentioned means permit to feed the boiler with a great amount of solid fuel of small size such as wood 48 or coal 49 which is retained by the elements 43, 44 so as to define only one sufficiently restrained drop mouth in the vicinity of the hearth 50 so as to feed the combustion gradually and permit a high autonomy of operation of the boiler.
  • the removability of one or both the elements 43, 44 is designed to permit feeding also with large pieces of wood logs as mentioned previously.
  • the angle of inclination 0( of the walls 102, 104 or 2, 4 relative to the horizontal plane preferably is between 45 and 60°.
  • the best inclination depends on the prevalent destination of the boiler which is to be fed either with small solid fuel or large pieces of wood logs; in the first case a greater inclination is required. If it is desired to facilitate sliding of the fuel along the walls 2, 4, 102, 104, it is preferable to superimpose on the refractory coating 29, 129 a wear sheet 51 as the morphological configuration of the surface of the refractory material tends to restrain by friction the descent of the fuel towards the hearth 50.
