Indirect gasification A new technology for a better use ASTM D388 18a Standard Classification of Coals by Rank

The brown coal is gasified in a bubbling fluidized bed using steam The residence time of the fuel in the bed typically is around 15 minut In the centre of the BFB a vertical tube riser is placed with an opening at the bottom through which the bed material containing coke is transported The riser is operated with air to transport the solids to the top and to combust the char from the 41 This classification establishes categories of coal based on gradational properties that depend principally on the degree of metamorphism to which the coal was subjected while buried
