| description | In the article there is considered one of directions of increase
of efficiency of use of coal — burning coal-water fuel (CWF).
There is developed a physical and mathematical models of the
combustion of droplets of CWF with division of the process into
a sequence of repetitive stages of evaporation and burning out of
the solid phase. The formula for calculating the time of burnout
of a single drop of CWF on the basis of the Sreznevsky equation
is obtained. The results of calculation of time of burning of a
drop depending on a radius of a drop and a moisture content are
presented. |
