This method Command purpose is handled using a number of uncomplicated instruments. Initial, the specified principal Handle (input) variable may be the coal-mill outlet temperature from the thermocouple located in close proximity to the point the place the coal/air mixture leaves the mill. The operator regulates the setpoint for this termperature on the automated controller, which in tum will Just about con­tinuously alter the ambient air-tempering damper in the hot inlet-air duct to maintain the specified mill outlet temperature at this predetermined established-· place. In the situation the place the cooler extra air is so incredibly hot which the ambient air damper, whether or not vast open, isn't ample to hold the coal mill outlet temperature underneath Risk-free amounts, there is an additional control loop which may be uncovered on most coal mill techniques.

5%. This ?�floating??Charge of the oxygen ends in improvements of the total flame duration. Knowledge has demonstrated the flame duration alterations are of minor magnitude in the event the oxygen level is controlled within this range, and considerably more Advantages may be derived in operating security than in the event the oxygen will be strictly controlled at a constant amount.

Buoyancy from the flame can typically be counteracted by a slight downward tilt of the main air pipe so the primary body on the flame is going to be centered at a particular distance In the burning zone. In Fig. 6.2, flame E shows a buoyant flame with the primary air pipe centered within the kiln axis. By tilting the pipe down slightly, the flame assumes the placement shown by flame File.
