High order dynamic models and observer design for coal Residues from the combustion of coal for energy production consist mainly of slag, ashes and flue gas desulphurisation gypsum. Residue generation has increased in the EU-15 by about 12% in the period 1993-2004, and now amounts to 3.5% of total waste generation.
