By the end of 2012, the recycled proportion of domestic waste tires was 287,330 ton (93.9%) of the amount of wastetires discharged (305,877 ton). The waste tires have been reused for heat supply, material recycling and other purposes;the proportions are 50.1%, 20.7% and 23.1%, respectively. In the case of heat supply, waste tires are supplied to cementkiln (104,105 ton, 68%), RDF manufacture facilities (47,530 ton, 31%) and incinerators (1,923 ton, 1%). Recently, therehas been an increase in the use of waste tires at power generation facilities as an auxiliary fuel. Thus, physico-chemicalanalysis, such as proximate analysis, elemental analysis and calorific value analysis have been carried out to evaluatepotential of waste tires as an auxiliary fuel in Korea. The LHV (Lower Heating Value) of waste tires is approximately20% higher than that of coal, at an average of 8,489 kcal/kg (7,684 ~ 10,040 kcal/kg). Meanwhile, the sulfur content isapproximately 1.5wt. %, and balance of plant (e.g. pipe line, boiler tube, etc.) may be corroded by the sulfur. However,this can be prevented by construction and supplementation with refractories. In this study, TDF (Tire Derived Fuel)produced from waste tires was co-combusted with coal, and applied to the CFB (Circulating Fluidized Bed) boiler, acommercial plant of 100 tons/day in Korea. It was combined with coal, ranging from 0 to 20wt. %. In order to determinethe effect on human health and the environment, gas emission such as dioxin, NOx, SOx and so on, were continuouslyanalyzed and monitored as well as the oxygen and carbon monoxide levels to check operational issues.
