Abstract

Burning off is the main method of carbon deposit removal from coke oven chambers. The heterogeneous reaction must be considered when the air blowing eliminates wall polycarbonate in the coke oven. In the three-dimensional problem of the burning off in the coke oven, the turbulent flow is induced by the interaction of the forced convection form the air inlet and natural convection from the high temperatures on the wall. This paper intends to show that the models can be generated by the solution of equations of conservation of mass, energy and spices in the boundary layer while lumping at the surface all the intraparticle effects. In order to understand the Sorect effect, there were three cases comparison. From the results, the Sorect effect is not clear, and P1 model has highly nonphysical behavior together with numerical instabilities inherent to the model.
