CFD analysis of a rotary kiln using for plaster production

Apr 11, 2018 Results obtained from the mass balance in the exergy analysis of the rotary kiln showed that excess combustion air was sent to the combustion chamber . The reason of this is that the combustion air is used as a momentum source for movement of the gypsum along the kiln. The temperature distribution in the rotary kiln should move parallel with ...

CFD analysis of a rotary kiln using for plaster production

The exergy analysis of the plant shows that most of the energy degradation occurs in the kiln. The analysis also enabled to assess the influence of the replacing fossil fuel by biomass on the increase of exergy efficiency of the plant.

Exergy assessment of a rotary kilnelectric furnace

Nov 01, 2017 The exergy balance of the rotary kiln is displayed in Fig. 3 b. Compared with the rotary dryer, the purpose of the rotary kiln is not only dehydration but also pre-reduction. Correspondingly, the exergy of purpose includes exergy flow of evaporation and laterite ores calcined. Therefore, the exergy efficiency of the rotary kiln is 26.93.
