General comment Grobalith® is trade name for bottom ash (coarse ash) from burning hard coal, where applicable with co-combustion of secondary fuels . Bottom ash is generated within the power plant's boiler room, resulting from the agglomeration of melted mineral compounds in hard coal combustion. It is considered a by-product of coal combustion. Bottom ash is not extracted with the flue gases, but collected in a water-filled hopper at the boiler end. Due to its physical properties bottom ash is applicable in a large variety. Similar to hard coal fly ash its chemical-mineralogical composition results from the used type of coal and varies from residual carbon and minerals to trace elements. Bottom ash is highly porous and in terms of its particle density comparable with natural lightweight aggregates. Bottom ash has irregularly ruptured, coarse surfaces and is suitable for the production such as light concrete products and light bricks. |
