The bottom monitor, located some five feet above the feeder, will trip the coal feeder if it senses a loss of raw coal flow. There are two coal feeders per mill, for a total of 14 feeders in the
Coal Feeder Failure Mode. Boiler Maintenance And Upgrades Attacking Tube. Boiler tube failures, especially in coalfired power plants, continue to be the major cause of boiler forced tube failure and inspection reports are provided for all of the.

In the process of deep mining, the coalrock masses were subjected to different types disturbance of dynamic loading, and they propagated to the depth of coal and rock in the forms of stress waves. It has been determined that coalrock masses mainly show shearcompression failures under static pressure. However, under dynamic loading, they had consistently demonstrated crashing or splitting

The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand. This ability to accurately weigh the coal provides significant improvement over volumetric types in terms of matching the fuel delivered by the feeder to the actual process energy required on coal fired units.
In traditional vertical coal bunker systems, a coalfeeder chamber (CFC) must bear the whole weight of the bunker. However, maintenance of CFCs within soft, swelling floor rock is a challenge faced in underground coal mines. Floorheave control is a complex problem and is still not wellsolved. Moreover, there is no report on the construction of bunker without a CFC, especially under such weak
