This method control operate is taken care of which has a handful of basic instruments. Very first, the selected principal control (input) variable is definitely the coal-mill outlet temperature from the thermocouple Positioned in close proximity 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 almost con­tinuously modify the ambient air-tempering damper in the hot inlet-air duct to maintain the specified mill outlet temperature at this predetermined set-· issue. In the case in which the cooler excessive air is so very hot the ambient air damper, even when wide open up, just isn't ample to hold the coal mill outlet temperature under Protected ranges, there is another control loop that may be identified on most coal mill systems.

To attain full combustion, the exact proportions of fuel and oxygen are expected with nothing at all remaining.

The flame turns into long and smoky and incomplete combustion happens. The end result can be an surplus of carbon, which combines With all the remaining oxygen and generates carbon monoxide.
