Chapter 7
Woody Biomass Fly Ash: Properties and Engineering Applications
Publication: Geoenvironmental Engineering: Site and Contaminant Characterization, Containment Facilities, Solid Waste Materials, and Contaminated Ground Interventions
Abstract
Biomass energy is generated from the combustion of wood and other biomass sources such as grassy or woody plants, wood waste such as sawdust, bark, or pallets, or some organic components of municipal solid waste, which can be combusted to produce energy. Woody and herbaceous biomasses are the most common forms of biomass fuels that are directly combusted or co-fired with coal for energy. This chapter focuses on the properties of woody biomass fly ash that results from the combustion of 100% biomass as the energy source. Biomass fly ashes with high-reactive lime, silicon, and aluminum content have self-hardening properties, which makes them successful binders for waste solidification compared to the self-hardening properties of four biomass fly ashes of varying compositions. Biomass ash is used as a soil amendment in agricultural applications, as adding alkaline ash balances the acidic effects of introducing nitrogen fertilizers while simultaneously providing necessary nutrients for plant growth.
