Combustion Ratio of Waste Tire Particle, PC and Mixture at Blast Temperature of BF

Keywords： blast furnace , waste tire particle , pulverized coal , combustion ratio ,

In order to study the combustion characteristics of waste tire particle （WTP）, pulverized coal （PC） and their mixture, the contents of CO, CO2 and O2 of off-gas during the combustion of WTP, PC and mixture under the condition of rich oxygen by 0--4% in blast and at 1 250℃ were measured simultaneously using synthetically infrared analyzer, and then the corresponding combustion ratio was calculated and compared. The results showed that the burning rate of WTP reached approximately 57%, which is much higher than that of PC （only about 18%） in the in- itial 650 s in fresh air, and then the increase of combustion rate of PC is faster than that of WTP; the combustion rate of PC improved remarkably with the addition of WTP. Meanwhile, the combustion rates of all these materials improved with the increase of oxygen content.
