Pulverised Fuel Ash
PFA is composed of inorganic material with a small proportion of carbon particulate resulting from incomplete combustion of the parent fuel, coal. PFA is extracted from flue gases discharged from combustion systems by electrostatic and mechanical processes.
PFA has no currently known eco-toxic effects in existing patterns of production, handling, storage and use.
Appearance: Semi-vitrified clinker-like granular material
FBA is composed of inorganic material with a small proportion of carbon particulate resulting from incomplete combustion of the parent fuel, coal. FBA is extracted from the combustion systems by a hydraulic process.
