This method Command functionality is taken care of by using a several easy devices. To start with, the selected primary Management (input) variable could be the coal-mill outlet temperature from a thermocouple Found in close proximity to The purpose in which the coal/air combination leaves the mill. The operator regulates the setpoint for this termperature on the automatic controller, which in tum will Pretty much con­tinuously regulate the ambient air-tempering damper in the new inlet-air duct to take care of the desired mill outlet temperature at this predetermined set-· level. In the situation exactly where the cooler extra air is so very hot the ambient air damper, whether or not wide open, is not really adequate to carry the coal mill outlet temperature underneath Protected concentrations, there is an additional Regulate loop which can be located on most coal mill units.
