Fossil fuels: ‘A restrictedrecource’ Natural gas, Oil and Coal
Biomass: ‘A renewablesource’ Wood (e.g. chips, pellets, bark, sawdust), agriculturalwaste, straw, peat, sludge, wastewood, pulp & paperresidues etc. • Alkalies: soda (Na2O) and potash (K2O) • Other elements: Calcium, Sulphur and Phosphor • Variable humidity • Soil and sand
Waste: ‘An inexhaustibleresource’ from household and industry • Chlorine • Alkalies • Iron • Sulphur and Phosphor • Variable metals • Variable energy output
Co-firing of differentfuels Highly variable conditionsregarding: temperature, humidity, ash, atmosphere, alkalies, acids, salts, metals, build-up and hot-melt slag
