Combustion and fuels in general Tina Stendal Svendsen Product Manager

Combustion: Fuel + Oxygen Carbon dioxide + Water + Heat/energy CH O 2 CO H 2 O + heat/energy Incomplete combustion 2 CH O 2 2CO + 4H 2 O + less energy

Fossil fuels: ‘A restricted recource’ Natural gas, Oil and Coal

Biomass: ‘A renewable source’ Wood (e.g. chips, pellets, bark, sawdust), agricultural waste, straw, peat, sludge, waste wood, pulp & paper residues etc. Alkalies: soda (Na 2 O) and potash (K 2 O) Other elements: Calcium, Sulphur and Phosphor Variable humidity Soil and sand

Waste: ‘An inexhaustible resource’ from household and industry Chlorine Alkalies Iron Sulphur and Phosphor Variable metals Variable energy output

Co-firing of different fuels Highly variable conditions regarding: temperature, humidity, ash, atmosphere, alkalies, acids, salts, metals, build-up and hot-melt slag Fossil fuels WasteBiomass
