Abstract: |
Many combustion experiments were finished by thermal analyzer. The igniting and burning regularity of charged pulverized coal comparison with original pulverized coal were evaluated comprehensively by ignition temperature, temperature of reached the fastest reaction rate, temperature of half burning-out for organic matter, burnout temperature, combustion characteristic coefficient. Experimental results confirmed the following conclusions: The ignition and combustion of positive corona charged pulverized coal are enhanced, the multiphase ignition and combustion of negative corona charged pulverized coal are decreased, the burning-out characteristics of charged high ash pulverized coal is reduced. In addition, based on the chemical bond theory, the change of charged pulverized coal surface chemical structure , this paper presents the theory of ignition and combustion for different polarity corona charged pulverized coal in heaps.
