China is the world's largest coal production and consumption Country，and is also one of the few countries which regard coal as the main sources of energy ,the coal energy rates was very high among energy consumption structure rates in our country.Among them, most of the coal combustion for power generation and heating industry.For large coal-fired power station and boiler,Pulverized coal combustion is the main way of combustion.However, It's one of the most important factors which has restricted the sustainable development that the use of pulverized coal combustion efficiency is not high and the environmental pollution caused by burning of our country one of the most important factors.
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.

China is the world's largest coal producer and consumer countries, is also one of the world on one of the few countries with coal as the main primary energy, the proportion of coal in China's energy consumption structure has been very high. Among them, the majority of coal combustion for power generation and heating industry. For large-scale coal-fired power plants and boilers, pulverized coal combustion is the main combustion. However, the use of pulverized coal combustion efficiency is not high and the environmental pollution caused by burning has been one of the most important factor restricting China's sustainable development.Based on comprehensive consideration of the pulverized coal combustion efficiency and low pollution, proposed the strengthening of the corona load coal powder combustion mechanism and experimental study. By high voltage electrostatic field to produce solid particles and gas charged role, on the one hand, the high mobile kinetic energy of the gas atoms or ions, contact with the coal particles, part of the energy transfer to the coal surface, causing the particles in an unstable high-energy state, increasing the particle surface activity; corona the other hand, oxygen, carbon monoxide, methane and other gases, ions, electrons of high energy, to speed up coal particle combustion reaction speed, reduce the temperature of the combustion reaction as possible. However, in actual production during coal combustion, coal is usually in the flow state. In theory, the flow of pulverized coal combustion efficiency is greater than the static pulverized coal, pulverized coal flow in the charged combustion enhancement is possible.On the basis of the coal particles charged through the use of the original electric whirlwind charged system, build a pulverized coal flow injection charge combustion system, the use of photographic records to analyze the ignition and combustion state, the use of sample thermal analysis method to analyze the fuel do, which explore the coal-bearing powder flow combustion conditions.
