Use Of Alternative Fuels In The 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.

Tire-Derived Fuel | Scrap Tires | US EPA

Tires can be used as fuel either in shredded form - known as tire-derived fuel (TDF) — or whole, depending on the type of combustion device. Scrap tires are typically used as a supplement to traditional fuels such as coal or wood. Generally, tires need to be reduced in size to fit in most combustion units.

Emissions from the Cement Industry - blogs.ei.columbia.edu

 · Indirect emissions from burning fossil fuels to heat the kiln can be reduced by switching to alternative fuels, including natural gas, biomass and waste-derived fuels such as tires, sewage sludge and municipal solid wastes. These less carbon-intensive fuels could reduce overall cement emissions by 18-24 percent from 2006 levels by 2050.

Use of MRF residue as alternative fuel in cement production

The two transportation steps are the shipping of fossil fuels to the cement kiln and shipping the MRF residue to the landfill. The total primary energy consumed in the SRF Case is the sum of the transportation energies, the total non-SRF energy used by the cement kiln, and the electricity related energy use to produce the SRF.

Energy Recover with Plastic to Energy Technology

 · The solid fuel's BTU content is similar to that of bituminous coal used in cement kilns—and significantly higher than sub-bituminous coals and lignite coals. An analysis of the test data showed that replacing coal with this solid fuel could reduce fossil energy use by approximately six percent annually at the cement kiln—equal to the ...

Biomass share in pretreated industrial or domestic wastes can come up to 30 or 50%. Pure biomass waste fuels used in the cement industry today are mainly animal meal, waste wood, sawdust and sewage sludge. While the use of alternative fuels contribute to reductions in CO2 emissions, they do not reduce the actual energy demand.

using alternative materials (as opposed to mining virgin fuels or raw materials). Cement manufacturers also save money by purchasing alternative fuel sources; for example, many cement plants that burn scrap tires as fuel (45 plants in the U.S. are permitted to do so) receive those tires free of cost or for only a small transporta-tion fee.
