Measuring Coal Pipe Flow stormeng

The clean air test conducted on each coal pipe is completed by multiple point measurements (usually 24 points of equal areas) using a standard pitot tube (Figure 3). The velocities of the 24-point averages are then plotted on a graph for ease of analysis (Figure 4). Clean air tests must be conducted under steady flow conditions with completely stable system temperatures. Ideally, the system
