| Abstract: | For the purpose of investigating the ignition and flame stability of low volatile pulverized coal, an in-depth analysis has been made on the lean flammability limits of gas-phase and pulverized coal combustion. The principle of separation of air from dust for the ignition of low volatile pulverized coal with primary air is presented. Experiments show that a new-type pulverized coal burner with a slit bluff-body designed on the said principle is suitable for the ignition and flame stability of low volatile pulverized coal. |
