This process control functionality is dealt with with a couple straightforward instruments. Very first, the designated primary Manage (enter) variable is definitely the coal-mill outlet temperature from the thermocouple located around The purpose wherever the coal/air mixture leaves the mill. The operator regulates the setpoint for this termperature on the automated controller, which in tum will Just about continuously change the ambient air-tempering damper in the hot inlet-air duct to maintain the specified mill outlet temperature at this predetermined set-· place. In the case where by the cooler surplus air is so warm which the ambient air damper, although wide open, is not enough to hold the coal mill outlet temperature underneath Harmless amounts, there is an additional Regulate loop that may be found on most coal mill methods.
