Slow-burning log

Abstract

The invention relates to warming, heating devices for warming and cooking, and it can be utilized in household, in the field, in camping and in any touristic events as a source of stand-alone flame for warming, cooking, as well as for illumination. A slow-burning log that is made of a solid-fuel material of a vegetable origin has upper, lower and side surfaces, at least two vertical through incisions that extend from the upper surface to the lower one and intersect with each other thereby forming a general through vertical hole that begins in a midsection of the upper surface. The vertical through incisions are made as partially inner incisions, and beginning from the upper surface they do not extend to the side surface of the log, while in the lower section of the log they extend to the side surface thereby forming side entrances for air delivery on the side surface. The vertical through incisions are made in a shape of trapezoid or rectangular grading into the trapezoid or a rectangular grading into another rectangular or in any other shape or in the form of any figure. The side entrances are made with dimensions calculated with consideration of air volume that is delivered therethrough and required to maintain uniform stable burning process. The slow-burning log comprises an ignition agent arranged at least in the general vertical through hole. The slow-burning log may be made with a removable support for a reservoir for cooking. The slow-burning log is made with a handle. Technical effect lies in increase of the burning time, provision of uniform long-term burning, provision of uniform cooling of the log body along the entire perimeter of the vertical through incisions while also providing uniform delivery of air from the bottom to the vertical through incisions along the entire perimeter thereof in order to provide stability of the burning temperature and uniform gradual burning of the log, allowing adjustment of the burning process providing slowing down thereof, increase of fabricability, reduction of labor intensity of production.

1 . A slow-burning log made of a solid-fuel material of a vegetable origin, the log having upper, lower and side surfaces, at least two vertical through incisions that extend from the upper surface to the lower one and intersect with each other thereby forming a general through vertical hole that begins in a midsection of the upper surface, characterized in that the vertical through incisions are made as partially inner incisions, and beginning from the upper surface they do not extend to the side surface of the log, while in the lower section of the log they extend to the side surface thereby forming side entrances for air delivery on the side surface.
