| Abstract: | Based on the theoretical relationship between gas-solid flow's centrifugal force change on outside and inside of bend and gas -solid flowing rate, we have made experimental research about measuring coal powder concentration in pneumatic pipes of boiler's combustion system with bend mehod. Then we have obtained a mathetnatical model for measuring the coal powder concentratuion in pneumatic pipes, done the error analysis, and provided a method of on-line measurement and its function. |

| Keywords: | pneumatic pipe of boiler coal powder concentration bend on-line measurement |
