Ash is the residue after combustion. Biomass ash is naturally alkaline. Ash content is usually small for wood but can reach up to 20% in mass for some biomasses (see Table 9.6).The alkali nature of biomass ashes tends to lower the fusion point of ashes leading to fouling and slagging.
Jun 15, 2020 · The measuring of the unburned carbon content (UBC) of fly ash and slag from biomass fuel generally adopts the national standard DL/T 567.6, which is applicable to coal-fired furnaces. In DL/T 567.6, the ash or slag sample is slowly heated to 815 °C in a muffle furnace, and the combustible content was calculated based on the mass loss.

Options for increased use of ash from biomass combustion and co-firing …
Ash: Ash is the incombustible solid mineral matter in a fuel. The percentage of ash produced by the combustion of the fuel is an indication of waste and loss in efficiency and also causes slagging and fouling on boiler surfaces. Low: Ultimate Analysis; Carbon: An increasing Carbon percentage results in an increase in calorific value of the fuel
Jan 11, 2016 · Slagging indices based on silica and alkali content of the ashes showed success for predicting boiler-observed slagging. The BioSlag test predicted observed slagging percentage in the boiler with R 2 = 0.87. This test could discriminate both high slagging of fuels with high Si content (e.g., rye straw pellet, pinecone seed shell) and the medium slagging tendency caused by alkali elements …
