Ltd, Mellacheruvu Cement works (MCW), Telangana state was established in the year 1998 with an installed capacity of 0.2 mtpa and has now attained a capacity of 10.0 MTPA. Solid AFR (Alternative Fuels and Raw Materials) feeding systems in cement kilns play a significant role in improving energy efficiency, reducing CO2 emissions, and supporting low-carbon strategies in cement production. The use of AFRs in cement kilns helps in transitioning toward a circular economy by utilizing waste materials, while also reducing the consumption of traditional fossil fuels like coal. Recently My home industries expanded a brown field project having 10000 TPD clinker capacity of Kiln in which the scope of installation of AFR feeding was more adequate and Feeding system was installed in the year of 2024 SOLID AFR FEEDING SYSTEMS IN CEMENT KILNS Cement production, especially the clinker production process in the rotary kiln, is one of the most energy-intensive processes, contributing significantly to CO2 emissions. AFRs are used in cement plants to partially replace fossil fuels like coal, reducing both cost and environmental impact. The key solid AFR feeding technologies used in cement kilns include: Types of Solid AFRs Used in Cement Kilns: • RDF( Refuse Derived Fuel ) coming from nearby localities • Firewood Chips • Palm Fiber • Plastic Hazardous waste
