The Moss tire processing system consists of a state of the art combustion system, plant controls and air emission systems that provide the correct solution to this problem. Moss will shred the tires into a size that allows the precise metering of the fuel into the combustion chamber. Moss has several different combustion systems (small to very large chambers) that are capable of burning shredded or whole tires with the correct fuel/air ratios in order to control system temperature and emissions. Our world class control system allows us to control the operation and eliminate upset conditions inside the system. Shredded scrap tires are called Tire Derived Fuel (TDF), which can be mixed with other fuels, such as coal, wood, chemical waste and municipal solid waste (MSW) that can be burned not only in a Moss combustion/boiler system but also concrete kilns, paper mills or large utility power plants.

As an energy source, TDF has a good potential compared to some other fuel sources. The most important thing to note is that TDF has a high fuel value of approximately 12,000 to 16,000 BTU's/lb. (compared to 12,000 BTU's/lb. for coal and approximately 5,000 BTU's/lb. for 50% moisture wood).

Other advantages of using TDF include the following:

  • Since TDF is a scrap/waste fuel, it generally is less expensive than fossil fuels.
  • TDF offers the potential advantage of decreasing emissions of sulfur oxides compared with high sulfur coal.
  • Piles of tires stored anywhere pose a fire hazard.
  • Instead of disposing of scrap tires in landfills, the extra space from tires can extend the life of the landfill.
  • Scrap tire piles pose risks since they provide an environment for mosquitoes, rodents, etc.
  • When burning TDF with coal in a cement kiln, the ash becomes an integral component of the product itself thereby eliminating ash removal.
  • TDF provides a consistent BTU and moisture content fuel in comparison to other fuels.

Areas of TDF Usage:

  • Moss combustion/boiler systems
  • Cement kilns
  • Pulp and paper mill boilers
  • Utility boilers
  • Industrial boilers
  • Foundry cupolas
  • Electric utilities
