Both the RUBBER MANUFACTURERS ASSOCIATION and the PORTLAND CEMENT ASSOCIATION have important things to say about the benefits of using scrap tires as fuel in Cement kilns. Click on their logos above to see how this important waste to energy use can benefit you.

Pound for pound, tires have more fuel value than coal.

Like fossil fuels such as coal, oil, and natural gas, tires are rich in hydrocarbons. Tens of millions of used tires are generated annually in the United States. By simply disposing of these tires, we miss an important recycling opportunity: the chance to recover their energy and conserve our resources of fossil fuels. Cement making is an ideal process for recovering the energy from whole scrap tires. The intense heat of the kiln ensures complete destruction. There is no smoke or visible emissions from the tires. In fact, because tires burn cleaner than coal, the use of tires as fuel can actually reduce certain emissions.

When it comes to using whole tires as fuel in Preheater/Precalciner or Long cement kilns, Cadence technology leads the way. Cadence offers three important technologies.

#1 The Mid-Kiln Fuel Injector

#2 The Suspension Burner

#3 Feed Shelf Entry Technology

These whole tire technologies along with Cadence Mixing Technologies are cost effective and easy to install.

PORTLAND CEMENT KILNS CAN BE SAFELY FIRED BY MILLIONS OF USED TIRES

Portland Cement Association (PCA) research supports previous findings that emphasize the environmental benefits of using scrap tires as supplemental fuel in the Cement manufacturing profess.

Portland cement kilns are especially well-suited for the safe and efficient consumption of the millions of used tires generated each year, Tyrone Wilson, Ph.D., director of regulatory affairs for PCA, said,

“The intense heat of the cement kiln ensures complete destruction of the tires. Because fire is contained within the kiln under intense heat, there are no visible emissions from the tires such as the heavy black smoke seen in an open-air tire fire.

This study shows that tires, which pound-for-pound have a greater fuel value than coal can also help manufacturers recycle tires without adversely affecting emissions,” Wilson said “The nearly 300 million used tires generated by the United States each year can create an environmental nuisance and eyesore. By simply disposing of these tires in landfills or junkyards, society misses an important recycling opportunity: the chance to recover energy and conserve fossil fuel resources.”

The study, conducted by Air Control Techniques P.C., is based on emission data collected by PCA from 31 cement plants presently firing tire-derived fuel (TDF). The emissions of particulate matter, nitrogen oxides, most metals, dioxin-furans, and sulfur dioxide from kilns firing TDF with conventional fuels were slightly lower than emissions measured from kilns firing only conventional fuels. The emission levels for carbon monoxide and total hydrocarbons were slightly higher for TDF-firing versus non-TDF firing kilns. None of these differences in emissions were significantly different.

Additionally, cement plants using TDF reduce the amount of coal burned. For each ton of TDF used, the plant reduces the need to use 1.25 tons of coal. This means that less carbon dioxide (CO2) is produced. CM
