Pulverized coal particles are used in oxy-fuel combustion power plants for electricity generation. Consider a situation where coal particles are suspended in hot air flowing through a heated tube, where the convection heat transfer coefficient is 100 W/m2·K. If the average surface area and volume of the coal particles are 3.1 mm2 and 0.5 mm3, respectively, determine how much time it would take to heat the coal particles to two-thirds of the initial temperature difference.

Pulverized coal particles are used in oxy-fuel combustion
power plants for electricity generation. Consider a
situation where coal particles are suspended in hot air flowing
through a heated tube, where the convection heat transfer
coefficient is 100 W/m2·K. If the average surface area
and volume of the coal particles are 3.1 mm2 and 0.5 mm3,
respectively, determine how much time it would take to heat
the coal particles to two-thirds of the initial temperature
difference.
