The coal quality of the fossil-fuel power station coal fired unit is worse

the ash quantity increases

and the air consumption of the pneumatic ash conveying system of the electrostatic precipitator increases obviously. In order to save energy and reduce air consumption

a new intelligent control system of double-casing pneumatic conveying is used to transform the ash conveying system. After the transformation of the intelligent pneumatic conveying system

it can monitor the change of the boundary conditions of the pneumatic conveying system according to the operating characteristics of the pneumatic conveying system of fly ash

and automatically and timely adjust the operating parameters of the conveying process

also can improve the pressure measurement point distribution and flow control adjustment

in the premise of satisfying the system output

gas consumption reduced by 25%. The application of intelligent control in ash removal system can obviously reduce gas consumption and improve production efficiency.
