Definitions

  • the present invention relates to an improvement in a stove, especially a wood-burning stove, having a draught regulator for primary air and a supply of secondary air.
  • a distinct disadvantage of the known stoves having separate adjustment of the primary and secondary air supplies is that it is very difficult to set the correct ratio between the amounts of primary and secondary air that are introduced. Incorrect adjustment will result in improper combusion, whether the amount of secondary air is too much or too little in relation to the amount of primary air introduced.
  • the stove illustrated in Figures 1 - 3 comprises a suitably-shaped stove body 1, a stoking door 2, a combustion chamber 3 and a smoke flue 4.
  • the various components can be made of cast iron, and the stove can be constructed in a conventional manner of cast parts which are assembled by means of appropriate fastening means and with stove cement.
  • the draught regulator in the illustrated example comprises a rotatable disk 10 on the stove door 2 as shown in Figure 4, and the draught opening 11 for the supply of primary air leads into the bottom of the combustion chamber 3 at its forwardmost end, emerging through openings 12 from a distribution chamber on the inside of the stove door 2.
  • the primary air flows substantially as indicated by the solid arrows 13.
  • the passageway 7 beneath the bottom 6 of the combustion chamber has an inlet 14 at the stove door 2, and this inlet is regulated also by an inlet opening 15 in the rotatable regulator disk 10.
  • the secondary air will flow as indicated by the dashed-line arrows 16 such that it enters the combustion chamber 3 at the top of the back wall thereof and ensures complete combustion of non-combusted gases.
  • flue gas which is a product of the combustion of both primary air and secondary air is formed, and the flue gases flow together over the shield 5 and out through the smoke flue.
  • the distinguishing feature of the present invention is that the supply of primary air and secondary is regulated simultaneously, which is obtained in that the rotatable regulator disk 10, as shown in Figure 4, also has openings for primary air and secondary air, and regulation of both air intakes occurs in that respective settings of the disk 10 will uncover or cover corresponding openings in the stove door itself.
  • the ratio between supplied primary air and supplied secondary air is determined by experiments and tests, and the size of the openings 11 in the door 10, for primary air, in relation to the openings 15 for secondary air, is determined on the basis of the results of these experiments and tests, such that one may be sure of obtaining at all times the air supply which gives optimum stove efficiency at any setting of the draught regulator.
