Abstract
In order to study the combustion characteristics of automobile waste tire and coal mixed fuel, the combustion characteristics of automobile tire rubber powder at 750°C / 800°C / 850 °C and pulverized coal at different mixing ratios under the combustion atmosphere of 20% O<sub>2</sub> / 80% N<sub>2</sub> were studied by isothermal thermogravimetric analysis experiment. The results show that when each component is burned alone, the weight loss of pulverized coal is mainly caused by fixed carbon combustion, the weight loss of automobile waste tire rubber powder is mainly caused by volatile combustion, and the burnout time of rubber powder is significantly less than that of pulverized coal; under different mixing ratios, with the increase of rubber powder, the calorific value of fuel increases, the burnout time shortens and the ash quality decreases; To sum up, the addition of waste automobile tire rubber powder improves the combustion characteristics of pulverized coals.
