Mar 01, 2013#0183;#32;In order to meet current production requirements, such as environmental and energetic restrictions are increasingly used alternative fuels derived from industrial waste. The cement industry has the potential of reusing waste from other industries as a substitute fuel or raw material. This activity is known as coprocessing,, .

technical, and economic impacts of using alternative fuels in cement kilns, but also compares alternative fuel use with other endoflife options. It outlines how the use of alternative fuels in cement manufacturing could improve the industrys overall competitiveness, while reducing the industrys costs and the greenhouse gas (GHG)
Petcoke is widely used as a supplementary fuel in the Cement Industries in many countries, including India. Petcoke (full name Petroleum Coke) is a residual product of the crude oil refining process. It has a high calorific value, but low volatile content, thus leading to poor ignition characteristics.
#0183;#32;Alternative fuel options for the cement industry Cement production involves the heating, calcining and sintering of blended and ground raw materials, typically limestone (CaCO 3) and other materials containing calcium, silicon oxides, aluminium and iron oxides to form clinker.

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.
4 Alternative fuel use in the cement industry . Currently, 73 % of all 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].
Jul 01, 2011#0183;#32;The use of alternative fuels and raw materials (AFR) for cement clinker production is certainly of high importance for the cement manufacturer but also for society as a whole. Alternative fuel utilization began in the mid 1980s. Starting in calciner lines, up to almost alternative fuel firing at the precalciner stage was very quickly achieved.
Nov 16, 2018#0183;#32;Written by Matt Drew, Saxlund International 31 March 2016 Cement production is one of the worlds most fuelintensive industries. Fossil fuels, mostly coal, have tended to be the industrys main power source, although increasingly, cement manufacturers are replacing up to 80% of their fossil fuels with more sustainable wastederived fuels (WDF).

ABSTRACT. Cement production is characterized by extremely high energy consumption per unit of product. Energy costs and environmental standards encouraged cement manufacturers worldwide to evaluate to what extent conventional fuels can be replaced by alternative fuels,, processed waste materials, such as scrap tires.

Their technology aims to enable the largescale commercialization of micro algae based fuels and coproducts. Algae can be cultivated in two ways in an open pond system (either naturally occurring or engineered) or in an engineered closed
Tons per year which could be used as an alternative fuel in cement industry [10]. In this study application of waste tires in cement plants, environmental benefits and its effects on producing clinker has been investigated. 2. DETAILS EXPERIMENTAL Cement Production Process in Iran
#0183;#32;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.
Typical raw materials used for cement production have 85% cayenne, 13% clay or blackboard, and under 1% each of materials such as silica, alumina, and iron ore. These feedstocks are crushed into particles with a diameter of less than 20 mm and mixed with a prehomogenization pile. (2)
The most significant alternative fuel energy contributors to the India cement industry are agrowastes and biomass fuels. A solution for alternative fuel should ensure the maximum availability of the kiln alongwith the alternative fuel feeding system and shall have minimum detrimental effect to the clinket production
Alternative Fuel Use in Cement Manufacturing 6 Emissions from cement production More than 50% of the total CO2 from cement production results from the chemical reaction that converts limestone into clinker, the active ingredient in cement. This chemical reaction accounts for approximately 540 kg CO2 per tonne of clinker.

The potential is enormous since the global cement industry produces about billion tons that consume nearly 350 million tons of coalequivalent fossil and alternative fuels. This study has shown...
