This method Command purpose is managed with a few very simple devices. 1st, the specified most important Manage (enter) variable may be the coal-mill outlet temperature from a thermocouple located around 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 adjust the ambient air-tempering damper in the recent inlet-air duct to take care of the specified mill outlet temperature at this predetermined established-· level. In the situation the place the cooler excess air is so very hot which the ambient air damper, even when huge open up, is not really adequate to hold the coal mill outlet temperature beneath Harmless concentrations, there is an additional Manage loop which may be discovered on most coal mill units.
