   Coal-combustion model; two-phase, with slip.

   Reactions: C (s) + 0.5 O2  > CO       (exothermic )
              CO    + 0.5 O2  > CO2      (exothermic )
              C(s)  + CO2     > 2CO      (endothermic)
              C(s)  + H2O     > CO  + H2 (endothermic)
              H2    + 0.5 O2  > H2O      (exothermic )

  Display
  Combustion of oil is similar to that of coal. The main difference
  is that the "saturation value" of the second-phase material in
  the first is set by the "transfer number", B, defined as the
  enthalpy differenc between the bulk of the gas and the gases
  adjacent to the liquid surface divided by the enthalpy increase
  undergone by the liquid to achieve vaporization.

  This value is if the order of 10.0 for many fuels.

  Therefore a value of cmdtc around 10/(1+10) has the right order of
  magnitude.

  It is the value employed here.

  Inspection of the profiles shows that, when the extra-air factor
  is chosen to be about 1.4, a significant amount of unburned vapour
  enters the gas stream.
