Unstratified downdraft gasification: Conditions for pyrolysis zone existence

Svishchev D.A., Kozlov A.N., Penzik M.V. Unstratified downdraft gasification: Conditions for pyrolysis zone existence // Energy Procedia. Vol.158. 2019. P.649-654. DOI: 10.1016/j.egypro.2019.01.177 Traditionally, the process of downdraft gasification is considered as a sequence of conversion stages, primarily running in separate reaction zones of a bed. These zones include the zones of fuel drying, pyrolysis, oxidation and reduction. There are experimental data and modeling results that do not agree...

Численное исследование режимов газификации угля и биомассы в поточном газогенераторе с парокислородным дутьем

Донской И.Г. Численное исследование режимов газификации угля и биомассы в поточном газогенераторе с парокислородным дутьем // Вестник Южно-Уральского государственного университета. Серия «Энергетика».. Т.18. №3. 2018. C.14-21. DOI: 10.14529/power180302 Процесс газификации биомассы (древесной, сельскохозяйственной и т. д.) может быть неустойчивым из-за низкой теплоты сгорания, а также сопровождаться образованием значительного количества смолы. Поэтому добавление угля способствует повышению эффективности...
