| Abstract: | Three-phase foam as a new technology was proposed to prevent the spontaneous combustion of coal. Experiments were done to research the characteristic of preventing spontaneous combustion of coal treated with three-phase foam by using spontaneous combustion testing apparatus. Speed of temperature rise and CO released were tested and the testing influencing parameters included types of coal, concentration of three-phase foam, concentration of slurry and size of granularity. The results show that the preventing effect of three-phase foam is remarkable. It can effectively depress the radiative velocity and control temperature of coal to rise and restrain quantity of CO released. 6figs., 2tabs., 8refs. |
