Работа посвящена численному исследованию процесса обращенной слоевой газификации древесной биомассы. Такие процессы используются для получения горючих газов на установках малой мощности. Для повышения качества генераторного газа предлагается использовать смесь древесного топлива с негорючим материалом, который может проявлять каталитическую активность при разложении нежелательных смолистых продуктов. Добавление негорючего материала снижает теплотворную способность смеси, однако способствует более глубокой очистке газа. Целью исследования является выбор оптимального соотношения «активный материал/древесное топливо» и определение минимальной активности материала, при которой его добавление к топливу становится эффективным.

The work is devoted to the numerical study of the process of downdraft fixed-bed gasification of woody biomass. Such processes are used to produce combustible gases at lowcapacity power plants. To improve the quality of the produced gas, it is proposed to use a mixture of wood fuel with a non-combustible material that can exhibit catalytic activity in the decomposition of undesired tary products. Adding a non-combustible material leads to lower heat value of fuel mixture, but contributes to a deeper gas purification. The aim of the study is to select the optimal "active material / wood fuel" ratio and to determine the minimum material activity at which its addition to the fuel becomes effective.
