To determine the conditions of heat transfer during thermal activation of the fuel, experimental studies of heat transfer while the fuel moving in a horizontal pipe were conducted. In the temperature range of 50 - 100°C, the value of the heat transfer coefficient α from the wall to the coal-water fuel is set, which averages 600-800 W/m2⋅K depending on the heat transfer conditions. The criterion equation of heat transfer during the thermal activation of coal-water fuel of Nu=f(Re, Pr) type was obtained on the basis of the experimental data. |
