Coal blending and process re-design for a steam generation plant

Abstract

Modern society has become more reliant on electricity, as more electrical conveniences are added to both home and workplace. This demand for electricity has resulted in the burning of large quantities of coal to produce a portion of the electricity needed. A byproduct of the combustion process is the resultant fly ash (incombustible mineral matter) that is left after all the organic components of coal have been consumed or driven off during combustion. An abundance of ash in the coal during the combustion process can impede the electricity generation process. This report seeks to highlight development into reducing the ash content of coal through coal blending processes, using ash scanning technology.
