Pulverized Coal Pipe Testing and Balancing

2016-5-3  Our approach to measuring dirty airflow in coal pipes (fuel and air) is to assemble a dirty airflow test kit (Figure 2) and an isokinetic coal sampling test kit to collect representative fuel samples for coal fineness analysis (Figure 3). Unlike other sampling methods, these two tests together allow the test engineer to
