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...

Influence of Technical Characteristics of Solid Fuels at Estimation of Emissions from Small Boiler Plants

....php/esr/article/view/2018.02.0005/20 The paper is concerned with the small-scale boiler plants, located in the coastal area of Lake Baikal. There are about 70 boilers of such kind (less than 1 Gcal/h) in the region. The fuel used by the boilers is wood and coal from various deposits. There is no data on harmful emissions into the atmosphere from the small-scale boiler plants in the Baikal natural territory. One of the indices that influence the amount of air pollutant emissions is technical characteristics ...
