Combustion Reactivity of Rice Husk：An Experimantal and Numerical Investigation

The combustion reactivity of rice husk from New South Wales,ustralia was measured by heating cubical baskets in controlled environment and monitoring the centre temperature.Frank-Kamenetskii‘s ignition theory was used to calculate the activation energy,Results agreed well with tests on other cellulosic materials,Numerical simulations of temperature changes were carried out,using a special technique to deal with non-linearities in the heat conduction equation.The numerical Results indicate that the time factor should be taken into account when evaluating self-combustion risks.
