Biomass combustion in fluidized bed boilers: Potential …

7/11/2019 · Biomass is considered a suitable coal alternative energy source because of its lower net emissions and acceptable heating values. The direct combustion of biomass in an industrial boiler can cause slagging and fouling of the boiler tubes because of the high content of alkali and alkaline earth metals (AAEMs) such as Na, Ca, Mg, and K present in the biomass. These minerals especially Na and …
