What is bridging in a silo? - sce.be
Stable bridging will not occur as long as bridges that are formed in a closed silo, yield when the opening is free. Bridges will collapse if the gravitational force is greater than the strength of the product. Products with a low bulk density are therefore more likely to give bridging problems.
What are Coal feeders? Principle, components ...
07-09-2020 · Coal Feeder is a device that regulates the amount of coal to be supplied into the Coal Mill. The amount of coal is regulated according to the needs in the boiler combustion chamber (furnace). The number regulation system in the coal feeder can be done in two ways based on the type, namely by weight fraction or coal volume fraction.
Gravimetric and Volumetric Coal Feed Systems for …
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.
