Alternative fuels have been used by cement manufacturers, in many countries, for several years. As per the latest figures available, percentage of replacement of oil and coal, by alternative fuels is given in Table IV. In conclusion, the author is happy to note that the use of alternative fuels is on the rise in the Indian Cement Industry.
If we look at the German cement Industry with an average alternative Fuel substitution of almost 61% in 2012 with solid alternative fuels, the production rates are only 90- 95% of the designed kiln capacity. With such high substitution rates of alternative fuels, the clinker production costs can be reduced by up to 10 € per ton of clinker!
PDF | Cement production has advanced greatly in the last few decades. The traditional fuels used in traditional kilns include coal, oil, petroleum coke, and natural gas. The substitution of fossil ...
This is the same total energy as consumed by approximately 1.6m Italians or 0.6m Americans per year. For fuel-related energy costs, the worldwide industry has largely moved to efficient preheater/precalciner processes and has found many options to switch to cheaper fuels, with the global drive to alternative fuels still proceeding.
2.2 Alternative Fuel (AF) Alternative fuel utilization in the cement industry started in the 1980s. Starting in calciner lines, up to almost 100 per cent alternative fu el firing at the pre-calciner stage was very quickly achieved. AF are mainly used tires, animal residues, sewage sludges (SS), and waste oil, as can be seen in Table II.

Dec 27, 2016· Nowadays, tire-derived fuel is gaining popularity as an alternative fuel in cement production. Transition to tires is caused not only by high traditional fuel prices, but also by environmental constraints. In this article, we describe Egypt's cement industry transition to alternative fuels.
Published by the Global Cement Magazine, this article provides an overview of the economic and sustainability benefits of alternative fuel usage in cement industry and refers to IIP's efforts to catalyze increased use of alternative fuels utilization in Indian cement industry.
The main advantages of using Alternative Fuels in the Cement Industry are economic and environmental. Cement producers strive to reduce their production costs. Fuel accounts for 20 to 25% of the production cost of cement and one viable option is the use of alternative fuels at a much lower cost than conventional fossil fuels.
cement industry The required energy input causes about 40% of the production costs for the manufacture of cement. Therefore apart from standard combustibles like coal, fuel oil and gas the so called alternative fuels are of considerable interest, besides a useful waste disposal their utilization offers important economical advantages.
The increased use of alternative raw materials in cement production is thus a core element of our climate strategy. At Group level, the proportion of clinker in cement amounted to 75.3% in 2017. The share of alternative fuels reached 2084% of our total fuel demand.
