Definitions

  • the present invention relates to a stove, and more particularly to a stove for burning solid fuel and being of the kind which comprises an outer casing or jacket having an openable and sealable front and incor ⁇ porating two mutually adjacent fuel-combustion cham ⁇ bers, and a flue duct which places the lower parts of the said chambers in communication with one another.
  • the object of the present invention is to eliminate the aforesaid drawbacks inherent with known solid-fuel burning stoves and, at the same time, to provide a stove which will burn fuel more effectively and in a manner which is friendly to the surroundings.
  • the inventive stove is characterized in that a first of the two combustion chambers is intended for slow-burning of the fuel charged thereto; in that the duct is operative to conduct gases of combustion from the first combustion chamber to the second of said two combustion chambers; in that the second combustion chamber is intended to function as an afterburner with respect to the first combustion chamber and also as a so-called fireplace in which solid fuel will burn with a higher flame; and in that the stove is constructed to enable solid fuel to be burned in either one of said chambers, separately or both at the same time.
  • Fig. 1 is a front view of a stove constructed in accordance with the invention
  • Fig. 2 is a view similar to Fig. 1 but with the front of the stove removed for illustration purposes; and Fig. 3 is a sectional view taken on the line III-III in Fig. l.
  • the illustrated stove has two front doors 1, a base or stand 2 and a flue pipe 3, which is provided with insulation 4.
  • the stove further comprises two combus ⁇ tion chambers 6, 7, each of which has a respective ash box 5.
  • the combustion chamber 6 shown to the left of Figs. 1 and 2 is fitted with a heat-reflecting device 8.
  • the other fireplace 7 has a fuel- box 9 into which fuel, e.g. logs, wood, coal is charged through a hatch 10.
  • fuel e.g. logs, wood
  • the fuel store or heat burns from the bottom and the smoke generated by the burning fuel flows from the fuel-box 9, through an interconnecting duct 11 and into the first of said combustion chambers, while passing an intake for secondary air of combustion provided in the duct 11 connecting said chambers.
  • the first combustion chamber 6 will thus function as an afterburner in the illustrated case, and therewith provide a "fireplace” in which slow-burning is obtained in a manner to produce an "open-fire” atmosphere.
  • the combustion chambers 6 and 7 are preferably dimensioned to suit the size of " the fire desired.
  • the heat reflector device 8 may be mounted on one edge thereof, so as to extend vertically, or substantially verti ⁇ cally, in the combustion chamber, and the flue gases may be caused to pass through flues, so as to heat the illustrated furnace lining 14.
  • the lining 14 may also be heated directly, by heat reflection from the device or devices 8.
  • the combustion chambers 6 and 7 are mutually separated by a partition wall 15.
  • the outer casing or jacket of the stove is made of metal sheet and the two front doors are made preferably of heat-resistant glass.
  • the inventive solid-fuel burning stove constitutes a fur ⁇ ther development of the heat-reflecting principle and is a combination of three types of fuel burner, i.e. a boiler with slow combustion, such boilers normally being installed in a separate room, a conventional stove which has a conventional open-fire facility, or a facility whereby the fire can be contained behind clo ⁇ sed stove-doors, and a stove which has an afterburner facility.
  • the fuel placed in the fuel-box 9 of the second combustion chambers will burn from the bottom over a period of from 4-8 hours, de- pending on the nature of the fuel concerned and on the quantity of fuel charged to the combustion chamber, and will in all events burn more slowly than the fuel charged to a conventional stove of this kind when all conditions are equal, without over ignition of the fuel, either in the one combustion chamber or in the other.
  • Fuel combustion is primarily controlled in the said second combustion chamber 7, over a selected length of time and under controlled conditions.
  • Fur ⁇ thermore, fuel-combustion is effected in the inventive stove in an "environmentally friendly" fashion, due to the reflection of heat by the reflectors 8 onto the stove-lining 14, i.e. because of the furnace-within-a- furnace construction of the stove.
  • combustion chambers 6,7 of the illustrated embodiment have been shown to be located side-by-side as seen from the front of the stove, it .will be under ⁇ stood that the combustion chamber in which the fuel- store is placed and in which the fuel is burned at a slow rate is located behind the combustion chamber in which fuel is burned with a higher flame, i.e. a "cosier" flame, as seen from the front of the stove.
  • the interconnecting duct 11 through which secondary air of combustion is introduced is incorporated in a separate stove-module which is fitted between the combustion chambers 6, 7 and which, particularly when the combustion chamber 7 containing the fuel store 9 is located behind the combustion cham ⁇ ber 6, extends over the whole width of the stove.
  • the heat reflecting device or devices 8 may also be built- in the partition wall 15 dividing the two combustion chambers, instead of constituting a free-standing part.
  • the outer casing or jacket of the inventive stove may be provided with means, e.g. a recess, for holding stones or like material which can be heated by the heat given-off by said casing, such as to produce steam when water is poured onto said stones, and therewith enable the stove to be used to produce steam in a steam sauna.
  • means e.g. a recess, for holding stones or like material which can be heated by the heat given-off by said casing, such as to produce steam when water is poured onto said stones, and therewith enable the stove to be used to produce steam in a steam sauna.
  • first chamber 6 may be used solely to burn the gases of combustion generated in the second combustion chamber 7.

Abstract

L'invention concerne une cuisinière brûlant du combustible solide, comprenant une structure extérieure (14) ainsi qu'un avant (1) s'ouvrant et se refermant hermétiquement. Ladite cuisinière comprend également deux chambres de combustion (6, 7) adjacentes, ainsi qu'un conduit (11) reliant les deux chambres à leur base. La première (7) des deux chambres de combustion est construite de sorte que le combustible solide (9) chargé dans ladite chambre brûle à partir du bas de celle-ci, et de sorte que les gaz de combustion produits dans cette chambre de combustion soient conduits dans la seconde (6) des chambres de combustion par ledit conduit (11). La seconde chambre de combustion (6) est conçue pour former une chambre de post-brûlage par rapport à ladite première chambre de combustion (7) et aussi pour former un foyer dans lequel du combustible solide brûle avec une flamme plus haute. On peut brûler du combustible soit dans la première (7) soit dans la seconde (6) desdites chambres de combustion, soit séparément soit simultanément.
