Combustion and fuel characterisation of wheat distillers dried grain with solubles (DDGS) and possible combustion applications

► Fuel properties of residues from wheat-based ethanol production were determined. ► Fluidized bed, grate and powder combustion, and ash characterisation. ► Powder combustion produced K- and P-rich fine particles, with risks of fouling. ► The slagging and bed agglomeration tendencies were high. ► Mixtures with Ca-rich logging residues reduced these tendencies considerably.
