This method control perform is managed using a number of uncomplicated instruments. Initial, the specified key control (enter) variable would be the coal-mill outlet temperature from a thermocouple located near The purpose where by the coal/air mixture leaves the mill. The operator regulates the setpoint for this termperature on the automatic controller, which in tum will Pretty much continuously change the ambient air-tempering damper in the hot inlet-air duct to keep up the specified mill outlet temperature at this predetermined set-· stage. In the situation in which the cooler extra air is so incredibly hot the ambient air damper, even though broad open, is not sufficient to carry the coal mill outlet temperature down below Safe and sound degrees, there is another Handle loop which can be uncovered on most coal mill units.
