Abstract:Based on the engineering and site tests the desiging of pipes of dense phase pneumatic conveying ash and the formula of calculating the distribution of velocity and pressure in the pneumatic pipe is systematized．The length and diameter of dense phase pneumatic conveying pipes are procured．The results show that the calculating formulas can be used as the foundation of design when the operating parameters are konwn． 

Keywords:pneumatic conveying；distribution of pressure；distribution of velocity
