Аннотация

В работе представлены схема получения синтез-газа плазменной газификацией твердых топлив и подробный анализ существующей литературы по горению синтез-газа (СО+Н2). Проанализированы и систематизированы основные известные кинетические механизмы окисления синтез-газа. Подобраны экспериментальные данные, использованные для их тестирования и найдены параметры применимости этих механизмов. Найдены и проанализированы экспериментальные данные по задержке воспламенения, скорости распространения пламени и концентрациям компонентов системы H2/CO/О2. Для этих данных проведена оптимизация кинетических параметров основных реакций механизма окисления синтез-газа. Модифицированные значения констант скоростей реакций остались при этом в пределах заданного интервала погрешности. Результирующий кинетический механизм горения синтез-газа находится в хорошем соответствии со всеми принятыми к рассмотрению исходными данными.
