The Heat Balance. The heat balance shows the important sources of heat energy and their relative contribution to Example Limestone is calcined in a rotary kiln Gaseous fuel at 900 K is busted with stoichiometric air to supply the required heat The limestone and air
Rotary kilns are usually heated by direct contact of hot gas flowing in opposite direction with the bed Figure 1. The fuel is fed to a burner located at the end of the kiln . Mostly the mathematical analysis is based on the heat and mass balance considerations for the countercurrent solid and gas streams to which some of the specific
rotary kiln with its main items. For all these items the energy balance is solved. Additionally the mass balance of each species is solved for the gas phase and the granular bed. The mathematical simulation is composed of the following submodels to take various chemical and physical changes into account.
