| Abstract: | A facility that can be used for pulverized coal combustion experiment in microgravity is described.It is used to study pulverized coal particles' pyrolysis,gasification,ignition,volatile release,char combustion and burnout,and other combustion characteristics in microgravity.The pulverized coal is blown into the furnace chamber intermittently.When the temperature reaches the set point,turn on the valve and put pulverized coal into the furnace chamber,and then observe whether pulverized coal can be ignited s... |
