use of alternate fuels in the cement industry

Coal is the basic fuel used in the Indian cement industry While it mainly provides the requisite heat and temperature the ash content in the coal also combines chemically with the limestone to help form cement clinker In India coal will of course continue to be the dominant fuel for a verylong time

In recent years the cement industry has been successful in reducing its operating costs and improving its carbon footprint emissions per unit of output by improving energy efficiency increasing the use of alternative fuels and deploying renewable energy sources

Use of alternative fuels as energy sources in cement industry is practice which is proven as very effective and which is used in cement factories in Europe and world more and more One of the biggest advantages of this concept is reducing of consumption of nonrenewable fossil fuels On the

An industry that is particularly well suited to the employment of alternative fuels is the cement industry There are a number of factors that promote the use of alternative fuels in cement kilns Of these factors the most notable are the high temperatures developed the appropriate kiln length the long period of time the fuel stays inside

The traditional fuels used in traditional kilns include coal oil petroleum coke and natural gas The substitution of fossil fuels by alternative fuels AF in the production of cement clinker

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 2700 degrees Fahrenheit during the cement manufacturing process

There are three key levers for reducing emissions from cement manufacturing in the short term improving thermal and electric energy efficiency reducing the clinkertocement ratio by blending with mineral substitutes and using lowercarbon alternative fuels to fire the kiln

resources when alternative fuels are used to replace primary fossil fuels in cementclinker kilns − The traditional sources of energy in the making of cement clinker are fossil fuels like coal lignite petroleum coke oil In coprocessing these are being substituted by wastederived

Adopting alternative fuel coprocessing in cement plant operations provides several important advantages such as reducing energy costs and fossil fuels consumption In some regions it contributes to mitigating local waste management challenges by reducing the amount of household waste that otherwise needs to be disposed of in the community

The use of alternative fuels can contribute to reducing primary energy consumption and nitrogen oxide emissions NOx in a cement plant and improving its carbon footprint thyssenkrupp has developed technologies – the prepol Step Combustor and the 2nd generation polflame burner – that permit great flexibility when it comes to the

4 Alternative fuel use in the US cement industry Currently 73 of all US cement plants use some type of alternative fuel Forty plants use tire derived fuel 15 plants use waste oil fuel 11 plants use solvents as fuel and 62 plants use some other material In some cases plants will use more than one type of alternative fuel 4

Japan Taiheiyo Cement has set out the measures by which it aims to achieve its July 2019 target to ‘reduce net CO 2 emissions per unit of cement production’ by 80 between 2000 and 2050 The measures consist of the introduction of energysaving equipment the promotion of alternative fuels AFs and the development of lowerCO 2 cements accounting for a minimum 15 reduction

Use of Alternative Fuels in Indian Cement Industry 349 TDF as alternative fuel The expenses require for the different trials and tests are imposed on that individual plant This is a costly affair and a stumbling block in use of alternative fuel in Indian cement plants Combustion in Cement Kiln

The Cement Industry Federation is a strong supporter of waste policy reform to help facilitate the safe use of alternative fuels and materials in Australian cement kilns The industry is focused on identifying opportunities for utilising materials that retain value in the form of energy content andor material substitution where this value can

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 747 in 2018 The share of alternative fuels reached 217 of our total fuel demand

Apr 20 2018 · The use of “other solid wastes” in the US cement industry increased from 90 thousand tonnes in 1993 to 13 million tonnes in 2014 which at an assumed LHV of 18 MJkg represented about 394 of the AF energy used in cement production 74 of the total fuel used 2

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

Cement production releases many emissions like carbon dioxide CO2 and nitrogen oxides NOx The cement production industry is under pressure to reduce emissions The use of alternative fuels in cement production is environmentally acceptable for two reasons preservation of non – renewable resources and reduction of waste disposal requirements

Major players in the Turkish cement industry intend to achieve these targets by increasing the use of alternative fuels and clinker substitution In its 201415 sustainability report Akçansa reported a clinker factor of 883 per cent in 2015 However the company plans to reduce this to 79 per cent by 2020
