New insights into biomass combustion ash categorisation: A phylogenetic analysis

چکیده
Combustion of biomass within power stations is a more sustainable way to generate electricity than the use fossil fuels provided feedstock sustainably grown. The physical and chemical properties combustion ash from different feedstocks were statistically analysed using 168 published database records. Plant taxonomy has strong influence on major element composition ash, that are burnt commercially can usefully be categorised as hardwood, softwood, grass crop residues, non-grass residues. most abundant elements in hardwood ashes calcium > potassium phosphorous, whereas softwood they silicon potassium. eudicot straw chlorine chlorine. Differences chemistry between categories visualised ternary plot normalised oxide, dipotassium dioxide contents. Other depend principally whether herbaceous or woody. Herbaceous produce significantly (typically 5–9%) woody 1–2%) their lower initial deformation (melting) temperature feedstocks, thus greater potential form slag foul furnace. These findings allow for impact characteristics include commercial operational decisions about station feedstock.

Faecal-wood biomass co-combustion and ash composition analysis
Fuel blending is a widely used approach in biomass combustion, particularly for feedstocks with low calorific value and high moisture content. In on-site sanitation technologies, fuel blending is proposed as a pre-treatment requirement to reduce moisture levels and improve the physiochemical properties of raw faeces prior to drying. This study investigates the co-combustion performance of wood ...

متن کاملElectrodialytic removal of Cd from biomass combustion fly ash suspensions.
Due to relatively high concentrations of Cd, biomass combustion fly ashes often fail to meet Danish legislative requirements for recycling as fertilizer. In this study, the potential of using electrodialytic remediation for removal of Cd from four different biomass combustion fly ashes was investigated with the aim of enabling reuse of the ashes. The ashes originated from combustion of straw (t...
متن کاملComprehensive transcriptome analysis provides new insights into nutritional strategies and phylogenetic relationships of chrysophytes
BACKGROUND Chrysophytes are protist model species in ecology and ecophysiology and important grazers of bacteria-sized microorganisms and primary producers. However, they have not yet been investigated in detail at the molecular level, and no genomic and only little transcriptomic information is available. Chrysophytes exhibit different trophic modes: while phototrophic chrysophytes perform onl...
