Coal Properties and its influence on Boiler Pankaj Ekbote ...

2013-11-27Properties of Coal Coal properties are evaluated by different methods. The most commonly used methods are Proximate and Ultimate analysis of the coal. Proximate analysis gives the Moisture, Ash and Volatile matter, while the Fixed Carbon is found by difference. Ultimate Analysis gives the elemental composition of the coal. Other methods like Macarel analysis is also used ...

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.
