New Modeling of Reaction Rate in Dust Combustion

Reaction rate play a major role in dust flame combustion. In this research a new reaction rate model is presented that is a function of time. An important advantage of the new model is that it is proportional to amount of fuel is burning at any time against previous models that were constant across the reaction zone. Flame equations of the lean dust combustion are solved by using the new model. Calculated values of flame speed are in good agreement with experimental data.
