Представлен анализ различных современных моделей окислительного пиролиза древесины. Некоторые модели были разработаны с учетом влияния только кинетики химических реакций, другие с учетом совместного влияние влажности, окисления угля и тепловыделения пламени. В работе представлена согласованность экспериментальных и расчетных данных для трех моделей. Результаты показывают, что эмпирические модели имеют некоторые недостатки, такие как слишком большое количество входных параметров модели, отсутствие исследований механического поведения древесины, ограничение условиями эксперимента.

This paper presents a analysis of different modern models for the oxydative pyrolysis of wood. Some models was developed involving the influence only chemical reaction kinetics, other involving the combined influence of moisture, char oxidation and flame radiation. In this study, agreement between the experimental and calculated results for three model is presented. The results show that the empirical models have some limitations, such as too many model input parameters, a lack of studies on mechanical behaviors of woods, limited experimental conditions.
