Abstract:
Amongst the challenges encountered by biomass combustion plants providing renewable energy, is the securing of fuel supplies as competition for biomass fuel use increases. This has led to the adoption of “combined fuels”, including wastes. Biomass combustion, however, releases species promoting corrosive degradation and there is limited understanding about their formation and deposition on heat exchangers. This study pre-evaluates the high temperature compounds’ releases from four fuel categories: herbaceous & grass biomass (HGB), industry food waste (IFW), agricultural plant & residue (APR), and wood waste fuels (WWF). It compares combustion release predictions from both biomass-applicable fireside indices (2S/Cl, Cl/K and K/Si) with MTData thermodynamic simulations. Indicators of increased fireside corrosion from fuel combustion include higher quantities of potassium species release (K-release) and lower 2S/Cl ratios. At 1100°C, MTData predicts K-release values increased: IFWAPR>HGB. Unlike other categories, WWF generated a variety of salts with temperature-dependent interactions, making indices application difficult.
