Experimental study of the dust
Feb 26, 2021A variety of dust control methods are often applied in coal mines, among which the application of wet scrubbers has proven to be an efficient technology for the removal of dust in airstreams, rather than diluting or confining the dust. In this paper, a wet scrubber design was developed. Based on a self-designed experimental test platform, the total dust concentration,

4 Coal Mining and Processing
The term coal quality is used to distinguish the range of different commercial steam coals that are produced directly by mining or are produced by coal cleaning. 3 Generally, coal quality for steam coals (i.e., coal used for electricity generation) refers to differences in heating value and sulfur content, although other characteristics such

Feb 11, 2014Running those fans can require a significant amount of electricity, which makes this system less suited for large plants that require a lot of steam such as those powered by coal or nuclear energy. They can, however, be used to support the thermal portion of combined-cycle natural gas plants (normally less than 50% of the plant's total output).

A Dry Sorbent Injection (DSI) system is, as the name implies, a dry process in which a sorbent is pneumatically injected either directly into a coal-fired boiler or into ducting downstream of where the coal is combusted and exhaust (flue) gas is produced. This discussion will focus on the latter, more common, implementation of DSI.
