На практике зафиксированы случаи самовозгорания соснового опада в холодное время года после выпадения атмосферных осадков в виде снега, что документально зафиксировано в лесном массиве Воронежской области. Цель исследований – экспериментально определить температуру начала термического разложения с образованием газообразных продуктов горения некоторых лесных горючих материалов. Для проведения экспериментальных исследований на предмет термической деструкции были отобраны образцы лесных горючих материалов на территории Брянской области – таких, как опад сосны и лиственницы, а также свежие иголки ели. Была собрана термографическая установка, определена температура начала термической деструкции, или разложения, опада сосны (Pinus sylvestris), лиственницы (Larix sibirica) и ели (Picea abies).</p></abstract><trans-abstract xml:lang="en"><p>This article presents the results of experimental studies investigating the thermal decomposition of pine and larch, as well as fresh spruce needles, using isothermal decomposition. This study will allow us to assess the fire hazard of the aforementioned forest fuels. Cases of spontaneous combustion of pine litter during the cold season, following precipitation in the form of snow, have been documented; this effect has been documented in a forested area of the Voronezh Region. The objective of the study was to experimentally determine the onset temperature of thermal decomposition, with the formation of gaseous combustion products, of certain forest fuels. To conduct experimental studies on thermal degradation, samples of forest combustible materials in the Bryansk region, such as pine and larch leaves, as well as fresh spruce needles, were selected. A thermographic setup was assembled for laboratory experiments, and the onset temperature of thermal destruction, or decomposition, of pine (Pinus sylvestris), larch (Larix sibirica), and spruce (Picea abies) litter was determined.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лесной горючий материал</kwd><kwd>возгорание</kwd><kwd>термографический анализ</kwd><kwd>лесные пожары</kwd><kwd>термическое разложение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>forest combustible material</kwd><kwd>ignition</kwd><kwd>thermographic analysis</kwd><kwd>forest fires</kwd><kwd>thermal decomposition</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования выполнены за счет гранта Российского научного фонда № 26-16-00015 (URL: https://rscf.ru/project/26-16-00015/)</funding-statement><funding-statement xml:lang="en">The research was carried out at the expense of a grant from the Russian Science Foundation No. 26-16-00015 (URL: https://rscf.ru/project/26-16-00015/)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Dhaundiyal A. &amp; Gupta V.K.
