The natural inclination always seems to be to calibrate annually, but often this may not be the best choice for eliminating the potential risk of bad measurements, or the most economical choice. The best way to think of it is to have the calibration time period tied to the critical nature of the measurement task and how often the gage is used.
"Blue the Mills"). Check and calibrate the coal feeders. Functionally check the full movement and position indication of all dampers. Review primary air flow curve to assure safe operation throughout the operating range assuring adequate minimum airflow as well as proper air to fuel ratios when above minimum airflow.
DESCRIPTION Coal feeder merupakan peralatan utama pada PLTU yang berfungsi mengatur laju aliran batu bara yang masuk ke mill untuk dihaluskan. Coal feeder bertugas mengatur banyak sedikitnya batu bara sesuai dengan kebutuhan yang diinginkan, yakni besarnya daya yang ingin dibangkitkan dari suatu sistem PLTU.
Coal feeder are mostly used in thermal power plants as coal is the main source of fuel for the combustion process. And in order to control the combustion correct amount of coal need to feed into the boiler to keep the process under control. As you see in the diagram feeder lies between the bunker and the crusher or coal mill.

The coal that has been set flow in the coal feeder goes into the mill to be smoothed. In the Coal Feeder also supplied air from the Air Fan which is useful to …
Bowl mills are used for pulverizing coal in pulverized coal fired boilers. The coal to the mill is fed by a coal feeder from the coal bunker. There are many type of feeders used for coal feeding like the belt feeder which can be in volumetric or gravimetric mode, the chain link feeder, the drag feeder, etc. Row coal from the yard is sized in crushers and stored in …
The Gravimetric Feeder compensates for the variation in bulk density by feeding a fixed weight of coal in response to a boiler demand. This ability to accurately weigh the coal on an "as-fired" basis provides significant improvement over volumetric feeders in terms of matching the BTU delivered by the feeder to the actual process
Hand-in-hand with ventilation systems are dust monitors. Because chronic exposure to respirable coal mine dust causes lung diseases that can lead to permanent disability and death, the U.S. Mine …
Step 1: Place the tool setter at a predefined position on the machine. Step 2: On MASSO go to F3-JOG screen, next move the tool in position on top of the tool setter and touch the tool till the tool setter shows exactly 0.00. CAUTION: Once in position DO NOT MOVE the tool before completing the next step. Step 3: On MASSO go to the F4-Tools screen and …
