  1. aDry basis ash free.
  2. bKg of dry air per kg of fuel burnt.
  3. cRadius of equivalent sphere. \( {E}_r={\left(\frac{3{S}_{\mathrm{vol}}}{4\pi}\right)}^{\raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$3$}\right.} \); S vol sphere volume (mm3).
  4. dSphericity. \( S=\frac{\pi^{\frac{1}{3}}{\left(6{V}_p\right)}^{\frac{2}{3}}}{A_p} \); V p volume of the characteristic particle (m3); A p surface area of the characteristic particle (m2).
