Abstract: This study proposes a novel approach to effectively solve the problems associated with reusing waste tires by injecting waste tire powder into the converter vaporization cooling flue (CVCF) to obtain gaseous fuels via CO2 gasification using high-temperature waste heat. The gasification behavior was investigated in a CO2 atmosphere using a thermogravimetry (TG)-mass spectrometry (MS) (TG-MS) system. A settling furnace was used to simulate CVCF to investigate the effects of gasification temperatures. The activation energy (E) was calculated using the Flynn-Wall-Ozaw (FWO) and Kissinger-Akahira- Sunose (KAS) methods. The main components in the gas phase were typically CO, CH4, H2, H2O, and C2H6 in a temperature range of 300°C–500 °C. The average activation energy of waste tire decomposition was 144.51 kJ/mol. The increase in temperature and decrease in particle size increased the amount of combustible gas and LHV value. The increase in the CO2/CO ratio decreased the content of residual coke from 12.62% to 11.98%. The lower heating values were determined to range between 8.75 and 10.27 MJ/Nm3. The research preliminarily confirmed the feasibility of injecting waste tire powders into the CVCF to generate gaseous fuels using waste heat via CO2 gasification.
