Slow-burning log

Abstract

A slow-burning log is made of a solid-fuel material of a vegetable origin, the log having upper, lower and side surfaces, upper and lower vertical incisions, which are made opened on the side surface, and which extend from the upper and lower surfaces respectively, towards the opposite surface without reaching it, wherein the lower vertical incisions are not coupled between each other and uniformly alternate with the upper vertical incisions, characterized in that the upper vertical incisions couple between each other inside the log body thereby forming a middle hole, in addition, the ends of the lower vertical incisions are higher than the ends of the upper vertical incisions, and the upper and lower vertical incisions are provided in an amount of not less than three respectively.

Description

(1) The essence of the claimed invention is explained by illustrations, which present:

(2) FIG. 1an overall view of the slow-burning log;

(3) FIG. 2a top view of the slow-burning log;

(4) FIG. 3a bottom view of the slow-burning log;

(5) FIG. 4a fragment of a side view of the slow-burning log;

(6) FIGS. 5, 6, 7examples of embodiments of the slow-burning log:

(7) FIG. 5an overall top view,

(8) FIG. 6an overall bottom view,

(9) FIG. 7a fragment of the overall side view.

(10) The proposed slow-burning log comprises: upper surface 1; side surface 2; lower surface 3; upper vertical incisions 4, which are coupled between each other thereby forming a middle hole 5, and lower vertical incisions 6.

(11) The upper vertical incisions 4 extend from the upper surface 1 towards the lower surface 3 without reaching it. The upper vertical incisions 4, which are made opened on the side surface 2, when penetrating inside the log body and coupling between each other in the central section of the log, form the middle hole 5 that begins in the midsection of the upper surface 1 and penetrates into the log body towards the lower surface 3.

(12) The lower vertical incisions 6 are made such that they extend from the lower surface 3 towards the upper surface 1 without reaching it and such that they do not couple and are separated from each other by the log body.

(13) At the same time, the upper vertical incisions 4 do not couple with the lower vertical incisions 6 and uniformly distribute with them.

(14) If the log has a regular round shape or a shape close thereto along the perimeter, the central longitudinal axis of the upper middle hole 5 may coincide with the central longitudinal axis of the log. In the embodiment of the log with three or five upper vertical incisions 4 and three or five lower vertical incisions 6 respectively, or more in the non-pair number, they are arranged approximately at equal angles and distributed uniformly along the perimeter of the log surface, wherein the lower ones alternate with the upper ones.

(15) The claimed slow-burning log may be made with a handle for convenient transportation thereof, the handle may be arranged on the upper surface 1 or on the lower surface 3, or on the side surface 2.

(16) Furthermore, for the sake of rapid ignition the slow-burning log may have an ignition agent mounted in the middle hole 5 and/or the middle hole may be soaked with a highly flammable substance.

(17) In separate case, e.g., in case of need in increase of burning intensity, walls of the upper vertical incisions 4 and lower vertical incisions 6 may be soaked with a highly flammable substance.

(18) The proposed slow-burning log is preferably used in any touristic events and in campings, as well as in fireplaces and bonfires as a source of long-term stand-alone fire for warming, cooking or as a source of light, in the following way.

(19) The slow-burning log is arranged by the lower surface 3 on a surface being suitable for arrangement of the burning device thereon or on a support that is arranged on the selected surface. The ignition agent arranged in the middle hole 5 or a wick of this agent extending therefrom is scorched. Afterwards, gradual uniform slow inflammation of the upper section of the slow-burning log occurs.

(20) Air is delivered through the upper incisions 4 from the side surface 2 and upper surface 1 to the burning zone, while the air cools walls of the upper vertical incisions 4 and the side surface 2 directly thereby enabling maintenance of stable slowed down burning process.

(21) Flame distribution front on the side surface 2 and inside the upper through incisions 4 and lower through incisions 6 uniformly and slowly moves from top to bottom until the complete combustion of the log occurs. In the course of after-burning of the upper section of the log, the flame is gradually distributed to the lower vertical incisions 6 that provides ignition of the lower section of the log and complete combustion thereof.

(22) After the slow-burning log is ignited, a reservoir suitable for cooking and/or warming water or a support for arranging the reservoir for cooking is arranged on the upper surface 1, if necessary. The support for arranging the reservoir for cooking is used for arranging the reservoir for cooking at a distance from the upper surface 1 and/or more reliable holding of the reservoir for cooking.

(23) Also, together with the slow-burning log a support for its arrangement at a distance from a surface may be used, the support, e.g., provides vertical position of the log in the case, when the surface is irregular.

(24) Preferably, the slow-burning log is made from timber, i.e. from a tree section coated with a bark. Various wood species are used, preferably, birch.

(25) It has been experimentally established that making upper and lower vertical incisions, according to the claimed structural solution being proposed, enables absolute combustion of the slow-burning log, non-breakage thereof into parts during burning and increase of convenience and efficiency of the device ignition.

(26) Upon comparison of the proposed technical solution with the analogues known from the prior art, it is concluded that the slow-burning log meets the criterion of inventive step, since it is presented with qualitative structural changes of making the incisions thereby producing an improved uniformly distributed ventilation system with associated structurally effectively functioning airflows for supplying air to the burning zone and also providing achievement of said technical effect being not established in the existing prior art earlier.

(27) Structures of the slow-burning log having the claimed set of essential features have not been revealed from existing sources of patent and scientific and technical information, thus, the presented technical solution meets the criterion of novelty.

(28) Also according to the results of experimental practice examination, the proposed solution is suitable for industrial use, since it does not contain any structural elements or materials, which could not be reproduced at the actual science and engineering development stage using the data disclosed in the description, therefore, the present technical solution is considered to be compliant with the criterion of industrial applicability.
