There is likely no other waste as difficult to dispose of as waste tires. What is waste tires made of? How could countless groups of scientists and inventers fail so miserably in making profitable use of waste tires? Both wet and dry grinders and shredders were tried at room temperature, as well as at hot and cold temperatures. None were truly profitable unless one spent a substantial fee up front to take waste tires!
Waste Tire to Oil Overview Waste tires to oil also named tire derived fuel (TDF). Waste tires (whole and shredded) have been used as fuel source by industries in many countries around the world including the U.S. This fuel is commonly referred to as tire derived fuel (TDF). A major use of waste tires is fuel. Tire Derived Fuel is the oldest and most developed market of waste tires in the U.S. Industrial facilities across the country, including cement kilns, pulp and paper mills and electric utilities use TDF as a supplemental fuel to increase boiler efficiency, decrease air emissions and lower costs. More than 52 percent of the 300 million waste tires generated annually are consumed as TDF in these facilities providing a cleaner and more economical alternative to traditional fuels.
Waste Tire to fuel Oil Processing
Waste tires pyrolysis is well known method for their thermal recycling by heating at near 500°C with purpose of liquid oil and carbon black by-production as near 50% and 35% yield correspondingly, and 15% wire steel cord in rest (all relatively to tire mass). First, put the raw material (waste tires, plastic, and rubber) into the furnace with auto feeder. Use coal, or wood, or natural gas etc as fuel material to heating the reactor in the combustion system. The reactor will slowly heat, when the temperature reach around 230℃, it will produce oil gas .Oil gas through catalyst chamber, top cooling pipe, and oil water separator, heavy oil is collect in the heavy oil tank. Other oil gas continues t o go through another cooling system and oil gas cooling down into light oil tank. Un-condensable gas can be recycled to heat reactor. Which can save energy? Lastly, when the temperature fall to 100 degree Celsius, worker could open the door of reactor to discharge of steel wire .In the same time, carbon black will be discharged automatically. Then can start another batch working.
