cement plants would increase to 115-130 kWh/t cement in 2030 and to 115-145 kWh/t cement in 2050. _____ PROCESS OVERVIEW – Cement is a solid material made of clinker, gypsum and other additives. It is mainly used to form concrete, a conglomerate of cement, water, fine sand and coarse aggregates, widely used for civil engineering constructions.
reductions, many cement plants have started using alternative fuels for kiln and/or calciner firing. This has created more challenges for the operation of a kiln because of the different characteristics of different alternative fuels such as calorific value, moisture content and chemical composition. ECS/ProcessExpert ensures successful

Written by Sussan Pasuki, Senior Alternative Fuels Manager, Leimen, Germany 01 February 2016 Fuel consumption is a key topic in the cement industry given the numerous issues involved, including costs, availability and environmental concerns.
Moreover, the use of natural gas as an alternative to the current energy source, fuel oil, was studied in two cases, associated with and without waste heat recovery system. Results showed that 34.28% of initial energy was lost in the base case, 48% of which is from flue gas and hot vent air streams.
mining, production and transportation of fossil fuels. In 2007 the use of 25,500 tons of alternative fuels reduced conventional fuels by 18,200 tons in clinker production. During the period 2003-2007, the use of alternative fuels nearly tripled. In the two plants, Kamari and Thessaloniki, in Greece where we currently use alternative fuels .
May 06, 2011 · Madras Cement's Alathiyur plant, for example, has demonstrated that burning of pet coke and alternative fuels such as coffee husk and cashew nut shells could result in a .
Increasing the use of alternative fuels at cement plants : international best practice (English) Abstract. This report, and an accompanying report on thermal and electric energy efficiency, provide a summary of international best practice experience in the cement sector and focus on specific technical measures that could be implemented by cement plants to .
alternative fuels (AF), in the U.S. and worldwide. The benefits of using AF, especially engineered fuel, in cement industry are discussed and two case studies are included: The use of AF in Plant 1 (annual capacity 2.5 million short tons) in the U.S. and the emissions of Plant 2 (annual capacity 7.6 million tonnes) in Mexico.
The major techniques are: capture and storage CO2 emissions, reducing clinker/cement ratio by replacing clinker with different of additives and using alternative fuels instead of fossil fuels.
The increasing use of alternative fuel sources will participate in saving 50m annually by 2025, in addition to reducing the current emissions of carbon dioxide resulting from cement factories.
and the use of alternative fuels in cement kilns. This practice has a wider benefit than merely reducing CO 2 emissions at the point of cement production. The global CO 2 emissions are reduced, but the reductions occur in other industry sectors than the cement industr y. To analyse the benefits of the use of alternative fuels in cement kilns,
In the fifties of the last century tyres were used for the first time as refuse derived fuel in the cement industry. Continuous use of various waste-derived alternative fuels then followed in the mid-eighties with "Brennstoff aus Müll" (BRAM) – fuel from waste – in the Westphalian cement industry in Germany.
Indian Cement Industry emitted 137 Mt of CO2 (2012), 7% of India's total man made emissions Low Technology Roadmap for the Indian Cement Industry has identified usage of wastes as Alternative Fuels and Raw materials as one of the key levers in reducing the GHG emissions
