The use of sorbents is also described more broadly than in their role as neutralizers. Sarenbo and Claesson [30] described the use of limestone and dolomite in Swedish heating plants for agglomeration of dust and ash after wood combustion. Better biomass combustion conditions and safe ash formation are also achieved by skillful fuel selection.

2022年8月1日 Whilst both fuels have similar ash contents of around 6 wt%, ash compositions differ substantially. Wheat straw has lower SiO 2 content, but roughly double the amount of K 2 O, Na 2 O and CaO. These alkali metal oxides (K 2 O, Na 2 O) are known to be integral to agglomeration behaviours [6, 31], but calcium has been seen to mitigate
