Manuscript Topics
Coal combustion accounts for approximately 25 % of the global CO2 emissions. Replacing coal with sustainable biomass as fuel would provide substantial CO2 emission reductions. SO2 emissions would also be reduced, because of the much lower sulfur contents of biomass based fuels compared to coal. Sustainability criteria of biomass used as fuel needs careful consideration. Cultivation of energy crops for fuel usage may compete with land usage for food production. Furthermore, sudden increase in the usage of forest based biomass as fuel would lead to short-term net increase in CO2 emissions for many decades due to their long carbon cycle lengths. There is also a risk that the cut forests do not necessarily regenerate as they were due to erosion effects after the protecting forest cover has been removed. Therefore, the short carbon cycle fuels, such as surplus agricultural residues should be preferred in energy production. Unfortunately, these fuels are technologically more difficult to combust due to their lower volume density, higher ash, alkali (K, Na) and chlorine contents compared to wood. The behavior of the inorganics in the combustors are responsible for the deposit formation and corrosion issues encountered. The excessive deposit formation and corrosion rate in biomass boilers have forced the plants to operate at lower temperatures and pressures than the coal fired ones, leading to lower conversion efficiencies. This special issue welcomes papers either with theoretical or practical approaches to understand, prevent or mitigate the deposit formation and corrosion issues in biomass fired systems.
