Ash Content - an overview | ScienceDirect Topi

The ash content of average biomass is lower than that of average coal. The ash in biomass is fine, while that from coal is in general coarse. For the low-ash mixed feed, one could expect a lower rate of ash deposition on boiler surfaces while cofiring biomass, but the reality is different. > Get A Quote >
