Underground Coal Dust Scrubbers in Coal Mining

As the coal dust present in the air poses multiple threats and is disruptive to the working process, multiple ways of controlling and reducing coal dust presence have been developed, one of which is coal dust wet air scrubbing. The most effective way to reduce the risks that come with coal dust present in the air is to significantly reduce the hazard by removing float coal dust from the airstream before it

New EPA Regulations on Fly Ash Handling DSI News

03/06/2015 DSI has experienced a recent uptick in inquiries regarding dust suppression for coal and fly ash applications as owners and operators work towards meeting these requirements. For fly ash handling, there are several new criteria that may require adjustments to owner and operator’s operating procedures. Controlling fly ash can be very challenging due to two physical properties of the material. First, fly ash is inherently moisture repellent, making the dust

Wet Scrubbers LDX Solutions The Geoenergy®

In some cases, wet scrubbers can be used to do both simultaneously. For example, in a process gas stream coming from a coal-fired boiler the gas stream contaminants may include both sulfur dioxide (gas) and fly ash particulate (solids) and both could be captured in a single wet scrubbing system. Wet scrubbers have been used in industry for many years and, as a result, there are a wide variety of designs. Most employ water or an aqueous solution to perform the scrubbing

Coal Cleaning an overview ScienceDirect Topics

Coal cleaning is used to remove ash and pyritic sulfur in coal [26,27]. Mercury that coexisted as pyrite can be removed by coal cleaning before combustion. Average mercury reduction by coal cleaning is estimated to be 20%–37% [28]. However, waste water for coal cleaning contains high-concentration mercury, which is classified as a hazardous waste. The cost of waste water treatment is very high.

Coal Ash Basics Coal Ash (Coal Combustion

Coal ash, also referred to as coal combustion residuals or CCRs, is produced primarily from the burning of coal in coal-fired power plants. Coal ash includes a number of by-products produced from burning coal, including: Fly Ash, a very fine, powdery material composed mostly of silica made from the burning of finely ground coal in a boiler.

An experimental study on the removal of submicron

In this study, a middle-scale wet electrostatic scrubbing (WES) setup was built to investigate its performance in the removal of both fly ash particles and black carbon, with special attention to the submicron size range. Major factors including the particle properties and charging conditions were expatiated in detail to popularize this method. The results showed that the efficiency increase in black carbon is significantly higher than that of fly ash
