Abstract：A new method of monitoring the status of branch pipes of PCI powder coal injection into BF based on measuring the concentration and velocity of coal powder using ECT(electrial capacitance tomography) with correlation is presented. All the abnormal operations of branch pipes, such as clogging, stopping and unimpeded transporting, can be detected and alarmed on line. The flow rate assigned to each branch pipe can also be computed continuously for uniform injection. The system was put in operation on 1BF of Baosteel. It has worked well for more than three years.
