Morphological forms of chars in slag and fly ash from the będzin power station, Upper Silesia, Poland

Vol. 7

189-198

Combustion of coal is still one of the main sources of energy and electricity in Poland. For cost reasons, and because of the need to protect the environment, it is important to use coal as efficiently as possible. One of the indicators of coal combustion efficiency is the amount of unburned organic matter in slag and fly ash. This organic matter occurs in different morphological forms. This paper provides an overview of the char morphological forms found in slag and fly ash from selected boilers installed in Będzin Power Station (Poland). The relative quantities of particular morphological forms are compared with the maceral composition of the feed coal. The aim is the better understanding of the influence that maceral composition has on combustion performance.

Composition and morphology of organic and mineral matter in fly ash derived from bituminous coal combusted in the Będzin power station (Poland)

Fly ash particles formed during coal combustion are composed entirely of organic or/and mineral matter. The proportions of the two components depends on combustion conditions and the presence of minerals in feed coal particles. The aims of this paper are the classification of char morphologies, the quantification of the inert- and semiinert components, and the characterisation of the morphologies and compositions of mineral particles in fly ash from Będzin Power Station, Poland. Various char morphologies are presented and their distribution in individual pulverised fuel boilers is discussed as are the morphologies of mineral particles and the distribution of major and minor elements in different size fractions of fly ash.
