This method Management perform is dealt with by using a couple very simple devices. Initially, the designated most important control (enter) variable is definitely the coal-mill outlet temperature from the thermocouple Found 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 Practically continuously alter the ambient air-tempering damper in the hot inlet-air duct to keep up the specified mill outlet temperature at this predetermined set-· level. In the case wherever the cooler surplus air is so hot that the ambient air damper, even though extensive open, isn't adequate to carry the coal mill outlet temperature beneath Harmless ranges, there is yet another Handle loop which may be found on most coal mill techniques.
