Tire derived fuel (TDF) are processed tires prepared for energy consumption. Following the Environmental Protection Agency’s (EPA) guidelines, specifications, and emissions testing standards – TDF is classified as alternative energy and can utilized as a fuel source for cement kiln, energy facility, pulp and paper mill power boiler, co-gen system, and industrial and utility power boilers. TDF contains 13,000-15,000 BTUs per pound. According to the U.S. Tire Manufactures Association, over 40% of US tires are processed into TDF. With the proper specifications and feeding system, tire derived fuel can be a viable fuel for:
- Traveling grate boilers
- Vibrating grate boilers
- Bubbling bed combustors
- Cyclone boilers
- Circulating fluidized boilers
- Stage combustors
- Cement kilns
- Lime kilns
