are a by-product of coal burning power plants. When pulverized coal is burnt at power plants, fly ash is produced. Cenospheres are the lighter particles present in fly ash and constitute about 1-2% wt.% of the fly ash [1]. Vassilev [2] indicates that cenosphere …

Pulverized coal-fired boiler - Wikipedia

The name 'cenosphere' comes from two Greek words: 'kenos' (hollow) and 'sphaira' (sphere). Cenospheres (or alumino silicates) can be formed at coal fired power stations. After burning of the coal, the resulting pulverized …

Characterisation of fly-ash cenospheres from coal-fired ...

During devolatilisation, some coal macerals soften and individual particles form different types and shapes of char particles. Based on shape, wall thickness, and porosity, these chars may be classified into three major groups: 'cenosphere', 'network/honeycomb', and 'solids', as illustrated in Fig. 13.25 (Gawronski, 1997). The different char types have different burning times according to the surface area …
