Особенностью данного оборудования является проведение процесса термоконверсии древесного сырья в камере пиролиза, оснащенной источниками сверхвысокочастотного электромагнитного поля (СВЧ). Пиролизное оборудование включает в себя блок получения генераторного газа из органических отходов, блок пиролиза древесины, систему продувки камеры пиролиза инертным газом, камеру дожига газовой смеси генераторного газа и пирогаза, блок регулирования температуры продуктов горения, теплообменник, дымосос, систему управления и контроля за работой пиролизной установки и дымовую трубу. В качестве источников СВЧ использовали магнетроны. Приведено описание методики проведенных испытаний оборудования по получению древесного угля в присутствии и в отсутствие СВЧ. В ходе испытаний использовалась древесина твердолиственных пород (колотые дрова клена). Результаты исследования указывают на то, что использование СВЧ позволяет повысить скорость процесса термохимической деструкции древесины, увеличить производительность оборудования для выработки древесного угля, а также получить больший выход древесного угля на единицу массы исходной древесины, сырье или продукт с большей теплотворной способностью и меньшей зольностью. Так, производительность экспериментальной пиролизной установки при отсутствии СВЧ составила 1,42 кг/ч, а в присутствии СВЧ – 1,73 кг/ч, увеличение составило 22 %. Разработанная технология получения древесного угля термическим пиролизом в присутствии СВЧ является экономически и энергетически перспективной. </p></abstract><trans-abstract xml:lang="en"><p>Experimental equipment for producing charcoal from sawmill residues using thermochemical conversion of biomass in an oxygen-free environment has been developed. This equipment features thermal conversion of wood raw materials in a pyrolysis chamber equipped with microwave sources. The pyrolysis equipment includes a unit for producing generator gas from organic waste, a wood pyrolysis unit, a pyrolysis chamber purging system with inert gas, an afterburner for the generator gas and pyrolysis gas mixture, a combustion product temperature control unit, a heat exchanger, a smoke exhauster, a pyrolysis unit control and monitoring system, and a chimney. Magnetrons were used as microwave sources. A description of the testing methodology for the equipment for producing charcoal in the presence and absence of a microwave field is provided. Hardwood (split maple firewood) was used in the tests. The results of the study indicate that the use of microwave technology can increase the rate of thermochemical destruction of wood, increase the productivity of equipment for the production of charcoal, and also obtain a higher yield of charcoal per unit mass of the original wood, raw material or product with a higher calorific value and lower ash content.For example, the productivity of the experimental pyrolysis unit without microwaves was 1.42 kg/h, while with microwaves, it was 1.73 kg/h, an increase of 22 %. The developed technology for producing charcoal by thermal pyrolysis in the presence of microwaves offers economic and energy-efficient potential. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>термохимическая конверсия</kwd><kwd>древесный уголь</kwd><kwd>пиролизное оборудование</kwd><kwd>дожиг</kwd><kwd>сверхвысокочастотное электромагнитное поле</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thermochemical conversion</kwd><kwd>charcoal</kwd><kwd>pyrolysis equipment</kwd><kwd>afterburning</kwd><kwd>microwave electromagnetic field</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Корсак, Е.
