Alternative fuels, or sometimes referred to as secondary fuels, are one of the main issues of modern cement production. firing waste materials of any kind with calorific burning value began in europe and japan during the mid of 1980s and meanwhile the entire world, including developing countries, is placing great emphasis on this matter.
Cement manufacturing is one of the leading energy consuming and heavy pollutant processes which is accountable for co 2, no x, so 2 emissions and some heavy metal discharge from the precalciner kiln system. in past few decades there has been an enormous amount of researches to reduce the energy and environmental cost by using alternative fuel and raw material.
2. alternative fuel options for the cement industry. coal is the primary fuel burned in cement kilns, however, the use alternative fuels in cement kilns is now common and increasing. the range of alternative fuels is extremely wide. they are usually available as gas, liquid and solid as shown in.
The cement industry has long been dependent on the use of fossil fuels, although a recent trend in replacing fossil fuels with alternative fuels has arisen. 1, 2 however, when unconverted or partly converted alternative fuels are admitted directly in the rotary kiln inlet, the volatiles released from the fuels may react with sulphates present in the hot meal to form so 2.
Xrf Helps Bring Alternative Fuels To The Cement Industry
Xrf helps bring alternative fuels to the cement industry. by ravi yellepeddi 08.12.2014. 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.
Blending with mineral substitutes, and using lowercarbon alternative fuels to fire the kiln. canadas cement industry has made progress over past two decades in each of these areas. energy intensity improved by 21 between 1990 and 2010. there have also been improvements in the clinkertocement ratio and the use of alternative fuels is growing.
Cement kilns operate at temperatures at which steel would melt. that, combined with the length of time which fuels spend in the kiln, means that the process releases their energy while completely and safely consuming them. alternative fuels have been successfully used in cement kilns for decades.

Attachment 6 Cement Kiln Process And Their Emission
Consistent with cement kilns around the world using alternative fuels. in the case of the malaysian cement kiln the use of solid shredded waste also known as pef has resulted in a reduction in nitrous oxide emissions of around 20 and a reduction in carbon dioxide emissions of.
Philippines: republic cement has signed a coprocessing agreement with century pacific group to burn postconsumer plastic waste as an alternative fuel. the deal is part of a move by the group to become plastic neutral by 2020, according to the philippine star newspaper. century pacific group includes brands such as century canned tuna and the shakeys pizza chain.
Dioxinlike pcb emissions from cement kilns during the use of alternative fuels. the substitution of combustion fuels in cement plants is increasing throughout many countries, and its individual performance is constantly assessed against strict regulatory standards. for cement plants within australia, normal operations remain to use petroleum.

Heat is produced by a fuel mix composed of traditional fuels and permitted alternative fuels (a cement kiln is specifically appropriate for alternative fuel usage due to very high combustion temperature, sufficient retention time and ability to capture mineral part in the clinker).
In europe, the cement industry has replaced a large part of its traditional fuel sources with biomass or waste. from a technical point of view, much higher substitution rates are possible, with some plants using up to 80 alternative fuels 1.. apart from direct effects of replacing carbonintensive fossil fuels with lowercarbonintensity of alternative fuels, there can also be indirect benefits.
In order to make cement, hightemperature kilns are needed. traditionally, coal is used in these kilns, but in the past two decades, many alternative fuels have been used. the term alternative fuel has often been used to disguise the fact that this fuel is actually waste, including tires, plastics, and petrochemical waste.
