Fuel qualities to indicate burnability are-
conardson carbon residue number- residue left in fuel after evaporation in a closed space.,
carbon to hydrogen ratio,
cetane number,.
Calorific value-Heat contained in unit mass of fuel.
CCAI- calculated carbon aromaticity index- ignition quality of residual fuels- can be calculated from nomograms provoded by the engine manufacturer knowing viscosity and density of fuel. the less ccai its better, normaly value around (850).It is developed by bp.
CII is calculated ignition index.....developed by shell
