This process Handle purpose is managed that has a number of uncomplicated instruments. To start with, the specified main Management (input) variable is the coal-mill outlet temperature from a thermocouple Found around the point the place the coal/air mixture leaves the mill. The operator regulates the setpoint for this termperature on the automated controller, which in tum will Nearly continuously change the ambient air-tempering damper in the new inlet-air duct to keep up the specified mill outlet temperature at this predetermined established-· level. In the situation in which the cooler excess air is so warm that the ambient air damper, even if broad open, is not enough to carry the coal mill outlet temperature underneath Harmless stages, there is another Regulate loop which can be found on most coal mill programs.
