The full name of TDF is tire derived fuel.
According to a research test conducted by a French company, the biomass components of waste tires include natural rubber, artificial silk, and stearic acid; The biomass content of second-hand car tires ranges from 17% to 20%, while that of second-hand truck tires ranges from 28% to 30%.
Due to the high content of biomass in burned waste tire derived fuel (TDF), the test results indicate that.
(1) Tire combustion emits less carbon dioxide, sulfur dioxide, and nitrogen oxides than high sulfur coal combustion.
(2) The ash residue of waste tires contains less heavy metals than some coal.
(3) Waste tires generate as much energy during combustion as oil, 25 to 50% more than coal, and 100 to 200% more than wood.
2. Fuel derived from waste tires has been widely used
In the 1950s, tire derived fuel (TDF) was first applied in Germany and is now widely used abroad. More than 40% of cement plants in the United States are burning waste tires; About 10% of Japanese waste tires are used as alternative fuels for cement kilns; Eastern European countries such as Poland and Ukraine use waste tires as the main energy source for rotary kilns (with a fuel substitution rate of over 60%).
The proportions of Holcim cement, Cemex cement, Heidelberg cement, and Lafarge cement tire derived fuels in alternative fuels are 10%, 16%, 11.6%, and 19.7%, respectively.
The tire shredder machine can shred waste tires to small pieces, small pieces tires are more complete combustion.
