This process control functionality is managed by using a handful of straightforward devices. 1st, the selected most important Management (input) variable is the coal-mill outlet temperature from the thermocouple Situated in close proximity to the point in which the coal/air mixture leaves the mill. The operator regulates the setpoint for this termperature on the automatic controller, which in tum will Just about con­tinuously adjust the ambient air-tempering damper in the hot inlet-air duct to take care of the specified mill outlet temperature at this predetermined set-· issue. In the case exactly where the cooler excess air is so hot that the ambient air damper, regardless of whether large open, will not be adequate to carry the coal mill outlet temperature below Secure levels, there is yet another Management loop that may be uncovered on most coal mill programs.
