A safety control system for a coal pulverizer utilizes signals (20,22) representing net oxygen and carbon monoxide measurements of the pulverizer atmosphere. A signal (50) representing the rate of carbon monoxide change is derived form the signal (22) by a derivative controller (48).

Improving Coal Pulverizer Performance and Reliability
Ball-Race Mills comprise the majority of coal pulverizers currently in service at power generating facilities. Figure 3 shows a cut-away of a Ring-Roll type coal pulverizer. In this design the grinding rolls are stationary, while the ring (or bowl, as it is sometimes called) is rotated by a worm gear drive. Powerful springs force the grinding rolls against the ring, providing the pressure

Coal Pulverizers
The main boiler was built as coal-fired, which is why pellets were ground in coal pulverizers that were slightly modified for biomass and operated at low temperatures to eliminate the risk of fire. Further modernizations and the addition of a fourth mill enabled that in 2014 the boiler was commissioned for 100% wood pellets [76].
