This process Handle purpose is taken care of with a couple of basic instruments. Initial, the designated main Regulate (enter) variable would be the coal-mill outlet temperature from a thermocouple Situated in close proximity to The purpose where by the coal/air combination leaves the mill. The operator regulates the setpoint for this termperature on the automated controller, which in tum will Practically con­tinuously regulate the ambient air-tempering damper in the hot inlet-air duct to take care of the specified mill outlet temperature at this predetermined established-· stage. In the situation where by the cooler extra air is so hot the ambient air damper, whether or not wide open up, just isn't ample to carry the coal mill outlet temperature beneath Harmless ranges, there is an additional Regulate loop which can be uncovered on most coal mill techniques.
