The invention relates to warming, heating, lighting devices, which represent a source of long-term stand-alone fire that can be utilized for using in fireplaces; in the field, in campings and in rest outside the city, in any touristic or other events. A slow-burning log is made of a solid-fuel material of a vegetable origin, the log having front, rear and side surfaces, through incisions, which are opened at the top of the side surface and which extend from the front surface to the rear one and, when penetrating into the log body, move apart at an angle with respect to each other and terminate in the log body. There are at least two through incisions made, at least two middle recesses, which intersect between each other at the top and intersect longitudinal incisions, are made at the top of the side surface, furthermore, the log has at least two longitudinal incisions at the bottom of the side surface, one of them begins at the bottom of the front surface in the middle section thereof, and another oneat the bottom of the rear surface in the middle section thereof, and which terminate in the log body in the region between the through incisions. At least two through incisions are made completely separated from each other by the log body. The middle recesses begin from the top section of the side surface and couple with the through incisions at a distance from the log center thereby forming a combined air channel with them, the channel having entrances for air on the front and rear surfaces and in the midsection of the side surface of the log. The longitudinal incisions are made vertically or concentrically, one of them extends from the front surface towards the rear one, while another extends from the rear surface towards the front one, and they are not coupled with each other. The log has an ignition agent that is arranged in at least one of the through incisions and/or in at least one middle recess, the log is made with a handle, with a flat surface at the bottom along the entire length. The technical effect lies in increase of the burning time of the device thereby providing uniform burning of the log along the entire length, elimination of breakage of the device into parts during burning with complete combustion of the device and, thus, provision of complete combustion.

Embodiments are described for a self-igniting assembly having a main portion with a match-like component affixed thereto. A flammable member such as a wick or match-like member is in communication with the match-like component. A handle permits the user to grip the main portion and tug the main portion to impart friction and a chemical reaction between the match-like component to ignite the flammable member. This assembly may be provided with a number of ignitable device such as logs, fire starters, fireworks, or candles.

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.

This invention provides processes and systems for converting biomass into high-carbon biogenic reagents that are suitable for a variety of commercial applications. Some embodiments employ pyrolysis in the presence of an inert gas to generate hot pyrolyzed solids, condensable vapors, and non-condensable gases, followed by separation of vapors and gases, and cooling of the hot pyrolyzed solids in the presence of the inert gas. Additives may be introduced during processing or combined with the reagent, or both. The biogenic reagent may include at least 70 wt %, 80 wt %, 90 wt %, 95 wt %, or more total carbon on a dry basis.
