Compressed Air Systems in Cement Plants
Compressed air systems are used in different parts of the cement plant. Although the total energy consumption of such systems are usually rather small, they are likely to be the most expensive energy in the plant due to very low efficiency - typical energy efficiency of compressed air systems is around 10%. Due to such inefficiency, using minimum amount or air, for the shortest time would generally be desirable.
Variuos measures can help run the compressed air systems at optimal efficiency and reduce their energy consumption and costs.
