Abstract:
Cement technology is very traditional and the basic principles have remained unchanged for a long time. However, very profound changes in the production techniques were introduced recently, leading to the diminishing of energy consumption.
Energy cost has affected manufactures to evaluate the substitution of conventional fuels with alternative fuels, i.e. processed waste. To be able to use alternative fuels as; waste oils, plastics, waste tire, sewage sludge, etc. it is necessary to know the composition of these alternative materials. So, the usage of waste organic materials affects the thermal energy in the heated furnace. It was used as an example of applying the results of this study in a cement production plant in Albania, which has started a strategy for the real studies allowing to use other alternative fuels.
In this study was used Aspen Plus simulation software to test the possibility for improving the energy performance of cement clinker burning oven process, while maintaining the same product quality.
For this purpose, were used data from real production practice. Mixtures of various organic materials were tested with Aspen Plus simulation software.
The results of different alternative material were compared with conventional materials such as oil, diesel, heavy oil, gas, etc. On the other hand, from the simulation results, it was identified as the most effective fuel source to minimize the material and energy cost.
