Cement Plant energy Audit

Cement is highly energy intensive industry whare energy and fuel cost accounts to 30 % of the overall production cost. The process of cement manufacturing involves calcinations where calcium carbonate is decomposed to form calcium oxide and lime. The calcium oxide reacts with various compounds, at around 1500 °C to produce clinker. The clinker is milled with gypsum and other additives to produce cement.

The input streams for the cement manufacturing include raw materials, fossil fuel, electricity, water, and compressed air. With temperatures rising up to 1500 °C, plenty of opportunities for energy consumption exist through application of thermodynamic principles.

Eco Energies expertise in finding the energy saving possibilities in cement industry. The following are some of the energy saving measures that can be implemented in Cement industry

• Optimum dispersion box height in riser duct and increase heat transfer in preheater.
• Installation multi-channel burners.
• Excess air optimisation
• Installation of high efficiency clinker coolers
• Upgrade to advanced automation system
• Installation of weigh feeders for coal feeding
• Installation of high tensile (HT) motors
