PURPOSE:To determine the coal output of a mill accurately, by measuring a pressure loss of a fuel pipe for connecting a pulverized coal mill and a pulverized coal burner and the flow rate of a primary air for fuel to be supplied to the mill. CONSTITUTION:A fuel pipe differential pressure measuring device 7 is mounted on a fuel pipe 4 for connecting a pulverized coal mill 2 and a pulverized coal burner 5 to measure a pressure loss DELTAP of the fuel pipe 4. A primary air flow rate measuring device 8 is mounted on a primary air supply tube 6 of the mill 2 to measure the flow rate Wa of a primary air. Then, the coal output of the mill can be determined accurately by a specified formula to prescribed correlationship between the pressure loss DELTAP and the flow rate Wa of primary air and the coal output of a mill.
