This method Manage functionality is handled with a couple very simple instruments. To start with, the selected major Regulate (enter) variable will be the coal-mill outlet temperature from a thermocouple Positioned around The purpose where the coal/air mixture leaves the mill. The operator regulates the setpoint for this termperature on the automatic controller, which in tum will Practically continuously modify the ambient air-tempering damper in the new inlet-air duct to keep up the desired mill outlet temperature at this predetermined set-· position. In the situation exactly where the cooler extra air is so warm that the ambient air damper, although huge open up, is not really sufficient to hold the coal mill outlet temperature beneath safe levels, there is another Manage loop that may be identified on most coal mill methods.
