Title: Study on Thermal Analysis on Combustion Features of Pulverized Coal
Abstract: A thermal balance was applied to study the combustion features of the Hegang fined coal samples and analyzed the particle,temperature rising speed ratio and oxygen concentration affected to the combustion features of the fined pulverized coal.The results showed that when the oxygen content was sufficient,the temperature rising speed rate was slow and the particle was below 60μm,the combustion performances of the small particle pulverized coal would be better than the large particle pulverized coal and the particle increased could make poorer to the comprehensive combustion features of the fined pulverized coal.The temperature rising speed rate increased would make the max weightlessness speed rate of the fined pulverized coal increased,the max weightlessness speed rate would make the relevant temperature increased and would be favorable to improve the combustion performances and comprehensive combustion features of the fined pulverized coal.When the oxygen content was below 20%,the oxygen content increased could improve the combustion performances and comprehensive combustion features.
