Alternative fuels form one of the main levers for CO 2reduction in the cement industry. According to IEA (2), alternative fuels can contribute Gtonnes .
A key area of action for CO 2 reduction in the cement industry is the fuels chosen to cover thermal energy requirements. The table below provides an overview of the development of fuel input in cement manufacture in Germany. It shows that the proportion of coal and lignite in the total thermal energy requirement has dropped from around 87 per cent in 1987 to around 62 per cent in 2000, and ...
Dec 27, 2016· Nowadays, tirederived 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.
Case studies and the technology around the burning of alternative fuels (AFs) in cement kilns are recurrent topics in International Cement Review and at Cemtech conferences. They have also often been the topic of the Technical Forum over the years and one of the themes of the Cemtech threeday technical workshops.
The Portland Cement Association (PCA) has been reporting alternative and waste fuel usage in the cement industry since 1977. During that period, the share of alternative and waste fuel usage has increased from minor amounts to 16 % of all fuel use in the cement industry in 2016.
Replacement of some conventional fuels with alternative fuels brings both ecological and economic benefits. An industry that is especially suitable for the application of such fuels, from the technological and environmental points of view, is the cement industry. Alternative fuels are used in many cement plants throughout the world.
Previously this organic waste would be sent to landfill or it would require incineration, but it is now used to reduce the reliance of fossil fuels in the firing of cement kilns. This alternative cement kiln fuel is created by innovatively processing and blending organic wastes to a strict protocol.
Cement manufacturing is an energyintensive process. High fuel costs are a primary issue, and alternative fuels have emerged as a potential solution. The cement industry is now burning a variety of alternative fuels or waste products in its kilns. The chemical composition of alternative fuels ...
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 precalciner 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.
Cementmaking is energyintensive. The spiralling cost of fossil fuels over the past two decades, combined with a move towards improved environmental performance, has led the industry to turn to alternative fuels to partreplace fossil fuels, such as coal and petcoke, to heat cement kilns.
Ireland: On 29 August 2017 an oral hearing began to hear submissions regarding plans by Irish Cement to use alternative fuels for energy in its plant in Limerick. The company is seeking to move away from using fossil fuels as a main source of material in its cement kiln in Mungret and to use recovered waste and tyres instead.
The slag industry has also reported similar issues with reuse in Italy. The consolidation of the local cement industry following the takeover of Italcementi and Cementir by HeidelbergCement and of Cementizillo by Buzzi Unicem should present a more unified industry approach towards alternative fuels.
natural resources, and provide lowcost, sustainable fuels. The cement industry has a long history of safe and efficient use of alternative fuels, ranging from used tires and biomass to a wide variety of secondary and waste materials. Cement kilns heat limestone and other raw materials to over 2,700 degrees Fahrenheit
2. Alternative fuel options for the cement industry Coal is the primary fuel burned in cement kiln s, however, the use alternative fuels in cement kilns is now common and increasi ng. The range of alternative fu els is extremely wide. They are usually available as gas, liquid and solid as shown in .
Although coal, petroleum coke, and other fossil fuels have been traditionally burned in cement kilns, many cement companies have turned to energyrich alternative fuels. Today, many plants use a wide variety of alternative fuels as part of their overall energy scheme; ranging from 10 to 70 percent of their energy requirements.
Jul 24, 2019· Italy: The Italian cement industry decreased its overall CO2 emissions by % in 2018 compared to 2017, in part by replacing a higher proportion of fossil fuels with alternative fuels and biomass fuels. The proportion of alternative fuels used increased to % in 2018 compared to % in 2019, according to Federbeton. This translates to 387,000t of alternative fuels.
