Based on the coal combustion efficiency and low pollution comprehensive consideration," corona charged pulverized coal combustion mechanism and experiment research" is put forward.By means of high voltage electrostatic field on the solid particles and gas can produce electric charge effect,On one hand, the gas atoms or ions moving kinetic energy is very high,and when contact with the pulverized coal particles,it'll transferred part of energy to the coal particle surface, and lead to Particles in an unstable high-energy state , increased the particle surface activity; On the other hand, oxygen, carbon monoxide, corona methane gas ion, electron, has high energy, those make accelerate coal particle combustion reaction rate, reduce combustion reaction temperature become possible. However, in the actual production process of coal, coal is usually in a flow state. From theoretic analysis, the flow of pulverized coal combustion efficiency of pulverized coal is greater than under the static state, Therefore,the pulverized coal flow in charge of combustion enhancement is possible.
In this paper,on the basis of pulverized coal particles are charged successfully, through using of the original cyclone electrostatic charge system to build the pulverized coal flow injection charge combustion system. using a photographic record and analysis of its ignition and combustion state, using sampling thermal analysis method of burnout to exploring Charged pulverized coal flow combustion status.
Key words: corona discharge, the pulverized coal flow, combustion, thermal analysis
