This method Command functionality is dealt with which has a couple very simple devices. First, the designated primary Manage (enter) variable could be the coal-mill outlet temperature from a thermocouple Positioned close to the point 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 modify the ambient air-tempering damper in the new inlet-air duct to maintain the specified mill outlet temperature at this predetermined set-· level. In the situation exactly where the cooler excess air is so warm which the ambient air damper, regardless of whether large open, is not sufficient to carry the coal mill outlet temperature under Safe and sound stages, there is an additional control loop which may be discovered on most coal mill devices.
