| Abstract: | It is discussed in the view of heat transfer, how fast the temperature would chage when coal pulverized particles come into industrial flames. The heat transfr betwee coal pul-verized particles and environments in the drop tube furnace and coal pulverized boiler is dis-cussed and compared with data of related experiments. The results show that heat transfer con-duct is the main way of heat transfer between particales and environmnts. And two kinds of particles with different sizes are discussed based on the characteristics of FBB. |
