primary air flow meter to coal mills thermo

Ultrasonic mass flow meter for solids suspended in a gas ...

In present practice, the coal flow rate into the pulverizer mills can be monitored with gravimetric feeders. The primary air flow rates from each mill are balanced before coal is added using standard pitot tube flow meters. However this method does not measure coal loading and continuous readings during boiler operation are not feasible.

Spontaneous Combustion - an overview | ScienceDirect Topics

Sometimes air locks are installed between the feeder and the coal mill and these tend to cause coal hold up, which can result in loss of coal feed to the mill, thus introducing an explosion risk. This is caused by rapid increase in mill temperature that occurs when the heat sink created by the coal drying process is lost.
