Know More About Fly Ash

Fly Ash
Fly ash, also known as coal ash or "pulverised fuel ash" in the United Kingdom, is one of the coal combustion products, composed of the fine particles that are driven out of the boiler with the flue gases. Ash that falls in the bottom of the boiler is called bottom ash. It is a general name used for the residual products of combustion that rise with flue gases. Chemically and physically, fly ash can have many forms depending upon the type of fuel burned and handling methods. A typical fly ash contains a significant amount of silicon dioxide and calcium oxide, which makes it frictional and abrasive. Usually, fly ash has a fine particle size distribution with most less than 100 microns. Given the fine particle size, frictional nature and high temperature, fly ash can be a difficult material to handle reliably.
In modern coal-fired power plants, fly ash is generally captured by electrostatic precipitators or other particle filtration equipment before the flue gases reach the chimneys. Together with bottom ash removed from the bottom of the boiler, it is known as coal ash.

Wide Applications of Fly Ash

  • Used as the replacement for Portland cement in concrete because of its pozzolanic properties.
  • Be used to construct embankment or other road. 
  • Grout and flowable fill production.
  • Waste stabilization and solidification.
  • Cement clinkers production (as a substitute material for clay).
  • Mine reclamation.
  • Stabilization of soft soils.
  • As aggregate substitute material (e.g. for brick production).
  • Mineral filler in asphaltic concrete.
  • Be used to melt ice on rivers, roads or parking lots.
  • Agricultural uses: soil amendment, fertilizer, cattle feeders, soil stabilization in stock feed yards, and agricultural stakes.

As we all know, fly ash has wide application, but its wide range of uses also increases the risks of environmental pollution. The usual pollution contains groundwater contamination and air pollution. Therefore, it is important to store fly ash to prevent it from polluting environment. Steel silo is one of the good choices for fly ash storage. And AGICO steel silo deserves your first choice if you decide to store fly ash in steel silo.

Fly Ash Storage Silo

AGICO Fly Ash Silo

In a typical fly ash handling system, the material that is generated as a result of combustion is captured by an electrostatic precipitator (ESP) or a baghouse before the flue gases reach the stack. These ESPs and baghouses generally have multiple pyramidal hoppers at the bottom, in which the ash is collected by gravity and then is transferred to a fly ash storage silo. These storage silos generally have provisions for a truck load-out to carry the fly ash for disposal or reuse. As a result of the frictional nature and fine particle size distribution, fly ash handling systems often experience problems if they are designed without following a prudent engineering approach. Fortunately, AGICO fly ash storage silo solve these problems well.
AGICO fly ash silo adopts the latest advanced technology and superior quality steel sheets. It meets the demands of storage of typical fly ash on site safely as well as economical usages. AGICO’s fly ash steel silo is designed professionally engineered to meet the customers’ requirements for performance, structural, and accessibility. What’s more, AGICO fly ash storage steel silo also allows simple transferring and tackling fly ash. Fly ash steel silo of AGICO comes with suitable interior coating support to provide for longest lasting tank possible. The advantages of fly ash steel silo built by AGICO are mainly as the following:

  • Expertise in offering right silo for right material storage and transfer needs.
  • Offering silos with complete structural support steel and access platforms.
  • Ash storage designs professionally engineered to meet customers’ requirements.
  • Meeting customers’ requirements for outstanding performance and convenient structural accessibility.

How to Clean Fly Ash Silo?

First of all, in the construction site of fly ash silo, you should set up temporary warning signs, and shall not exceed the specified construction scope. Moreover, no irrelevant personnel enter the construction site. Close the pipe from which fly ash comes into the silo, and wire tied up, hanging warning signs. When the fly ash is not in, the downstream equipment such as the bottom of the base should be put into the maintenance position.
Library lighting lamps should be placed into the fly ash silo from the hole in the middle of the top, the cleaning staff shall not be exposed to lighting tools and lines. In the fly ash silo cleaning process, the number of people outside and in the silo should be more than 2:1. And professional staff should be sent for monitoring outside of the fly ash silo. Enter the silo after confirm this: From the top of the door to confirm the safety of base stacking and observation the ladder’s firmness and the top of the silo To enter the fly ash silo, the construction personnel should wear labor protection supplies, including anti-dust masks, goggles, safety shoes, safety helmets etc.
When entering the fly ash silo, the personnel have to fasten two safety ropes, one fixed in the library outside the dust collection device support, the other fixed pool on the ladder. When start cleaning, the speed of feed into the mill should be based on the flow of the situation; if the flow is too small, in the upper part of the rotor balance pipe put ash, put down the fly ash mixed with the mixed material to do the mixture First poke the fly ash in the bottom of the pool with iron bars and compressed air; then blow in the slio’s top with compressed air; into the silo after the first use of compressed air blowing, long stab sticking fly ash, the last available shovel and pick. Kindly notice: at the beginning people from materials far, beware of the falling material.
If you need to take a shelf in the fly ash silo and other aerial work should be strictly comply with the relevant provisions of the high-altitude operations It is prohibited to use explosives to clean up the fly ash silo. If there are special circumstances, special safety measures should be developed before the construction.
After the process of coal ash silo cleaning is completed, and passing the acceptance of the construction site after the completion of a thorough clean-up, the cleaning work can be over.
