This process control purpose is managed using a couple uncomplicated instruments. To start with, the designated main Command (enter) variable is definitely the coal-mill outlet temperature from a thermocouple located in close proximity to the point wherever the coal/air mixture leaves the mill. The operator regulates the setpoint for this termperature on the automated controller, which in tum will Pretty much con­tinuously alter the ambient air-tempering damper in the hot inlet-air duct to take care of the desired mill outlet temperature at this predetermined set-· issue. In the case the place the cooler excess air is so warm the ambient air damper, although extensive open, will not be ample to hold the coal mill outlet temperature underneath Protected ranges, there is yet another Management loop which may be located on most coal mill systems.
