| Abstract: | This paper is to study how the pressure fluctuates along the pipe under differential ratio of solid to gas when the back-pressure is settled at 0.1MPa. A set of experimental apparatus which is corresponded with the gas/solid injector used to transport the coal powders in demonstrated power station of JiaWang XuZhou was designed and established. Through the experiment, two conclusions were obtained. One is that generally speaking, the pressure alo ng the pipe is decreased, but in somewhere, it is increased for the inflation of the air jet. The other is that with the increase of ratio of solid to gas, the pressure of gas flow used to transport the particles must increased in order to improve its capacity of work. |
