Definitions

  • the present invention consists in contributing an appliance that uses biomass as fuel, equipped with closed combustion chamber, which incorporates a fuel feeding system in the form of briquets made of pressed sawdust using a high tonnage press.
  • a fuel feeding system in the form of briquets made of pressed sawdust using a high tonnage press.
  • This fuel has been designed for the appliance according a specific geometric shape and dimensions, which is loaded to the stove around the combustion chamber. The fuel drops by gravity into the lower portion of the heater; next, each briquet is raised through the side portion of the supporting structure of the appliance by means of an internal conveyor.
  • the movement of the fuel (briquets) conveyor is performed by a stepper electric motor, i.e. the motor feeds the briquets one by one into the fuel chamber according to the heating needs of the environment by means of a thermoelectric control mechanism.
  • the stove can also be used to heat water in commercial and industrial boilers.
  • the appliance can be provided with a ceramic glass in its front part, so that the user can see the intensity of the fire, although access to the stove by introducing directly the fuel into the chamber is not possible, according to the principles already indicated for this invention.
  • the present invention means a technical and practical solution that permits to control the fuel load to the stove, a feature that has not been contemplated in the current units equipped with combustion chamber through radiation; in this way, the aspect of environmental pollution can be controlled, especially in the cities already referred to in this specification.
  • the client can enjoy autonomy, inasmuch as he/she is not permanently concerned with the introduction of firewood to the heater in order to avoid its becoming extinguished.
  • FIG 2 it is illustrated a scheme of the operating principle of a traditional firewood range without a double combustion chamber.
  • combustion chamber can be made of steel and can correspond to the double or single combustion type.
  • Figures 4 and 5 describe the form of loading the appliance with briquets.
  • briquets (2) are orderly introduced into the heater, since the fuel concerned has fixed and regular dimensions.
  • the briquets descend by gravity to the pitch sheave (3) that includes radial lugs, which is driven by a stepper electric motor (4).
  • the pitch sheave (3) permits that briquets pass one by one into the conveyor (5).
  • Said conveyor (5) may correspond to a chain mechanism equipped with devices for guiding the briquets (2), being driven by toothed pinions made of steel or other heat-resistant material; the pinions are connected by means of an axis made of steel or other suitable material.
  • thermoelectric signal In the normal operating phase, once the stepper motor (4) is driven by means of a thermoelectric signal, the following simultaneous movements are produced:
  • Figures 6 and 7 illustrate the initial manual ignition mechanism of the heater; this takes place by displacing the ignition lid (6) in order to enable the introduction of an inducer element, paper or the like, which through a match can cause the ignition of the briquets (2) placed over the rack or grid (7) inside the combustion chamber (8).
  • Said ignition lid (6) can be opened to a greater or lesser extent in order to permit the entry of a greater or smaller air flow into the combustion chamber (8).
  • Figure 8 describes the fuel entry control systems into the combustion chamber. There are two options for controlling the entry of fuel into the combustion chamber, namely:
  • FIGS 9 and 10 illustrate the main forms in which the appliance of the present invention transfers heat into the environment, namely, by means of radiation through the glass and the upper part of the heater and by forced convection through the air flow entering by the heater rear part operated by the turbine (13), which drives the environmental air through the heated external surface of the combustion chamber and thereby picks up the heat generated by the combustion chamber (8).
  • Said turbine can be a steel fan driven by an ad boc electric motor.
  • Figure 11 describes the form of extracting the ash generated by the briquets combustion inside the combustion chamber.
  • the procedure consists in opening the lid (6) and displace it laterally and by means of the scraper (14) the ash into the rear part of the rack is moved (7), which falls into the ashtray (15); the latter element can be extracted by the user from the supporting structure (16) of the stove for its disposal.
  • Said ashtray can consist of a metallic pan for retaining the ash, from which ash can be eventually extracted by the user for its elimination.
  • Figure 12 illustrates a traditional firewood range incorporating the feeding mechanism with fuel side loading (briquets) according to the present invention.
