This process control operate is handled with a handful of straightforward devices. Initial, the selected primary Regulate (input) variable would be the coal-mill outlet temperature from a thermocouple Positioned close to the point where by the coal/air combination leaves the mill. The operator regulates the setpoint for this termperature on the automatic controller, which in tum will Nearly 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 established-· point. In the case the place the cooler excessive air is so hot which the ambient air damper, regardless of whether extensive open, just isn't sufficient to carry the coal mill outlet temperature underneath Protected concentrations, there is an additional Management loop which can be observed on most coal mill methods.
