| Abstract: | A novel burner fired pulverized coal-a general main burner with double primary air tunnels and using high speed jets with large velocity difference has been presented in this paper, which not only remains the good features of combustion technology of high speed jets with large velocity difference, but also completely overcomes its shortcoming in easily slagging inside burner, so that a main buner which can operate for a long time without slagging has been developed from a prechamber and has some good features, such as wide adaptability in coal type fired, wide range in low load operation and controllability in ignition location of pulverized coal. |
