Introduction of fly ash silo
Fly ash is a useful material in a lot of areas, it is one of the product
after the burning of coal, composed by exiguous particles that are
driven out of a boiler with the flue gases. In chemical and physical,
there are many forms of fly ash, the typical type of fly ash contains
much silicon dioxide and calcium oxide, which make it frictional and
abrasive. Usually, the size distribution of fly ash with most less than
100microns. It is a kind of material that hard to handle because of it’s
characteristic of fine particle size, frictional nature and high
temperature. Nowadays, fly ash is captured by electrostatic
precipitators or other particle filtration equipment generally before
the flue gas reaches the chimneys. With the coal ash that removed from
the bottom of the boiler together called fly ash.
Uses of fly ash
Fly ash is wildly used in many areas, here are some examples, fly ash is
a necessary building material that we can usually seen in cement
production, embankment and other road construction. Anyway, fly ash is a
useful material in different industries. Since the fly ash applies in
so many areas, there is also a potential risk behind the using of fly
ash, environmental pollution and ground water contamination. It is
necessary to store the fly ash well.
Choosing a container to store fly ash without leakage is the most
effective way to keep fly ash from pollute the air and the water. Fly is
a good choice for you. We can provide you different models of fly ash
silo for you.
-
Advanced technology. Flyer fly ash silo adopts the most advanced silo
building technology form a Germany engineer. The double-seam technology
makes the silo seals extremely well and stable.
-
High quality material. Flyer has a long term cooperation with
Han-Steel. Han-Steel was one of the steel supplier of the manufacture of
the 2008 Olympic stadium, Bird Nest.
-
Stable performance. Flyer fly ash silo is designed to meet the
customer’s requirements, the structure is stable and the maintenance of
the silo is easy and simple.
-
Low cost. Flyer steel ash silo is simple in structure and it is easy
to construct. The construction period is short and need less workers
than other silo. The silo can serve at least 35 years.
How To Clean Fly Ash Silo?
First of all, in the construction site of fly ash silo, you should set
up temporary warning signs to warn that no irrelevant person should ever
enter the construction site.
Seal the pipe where fly ash comes into the silo, and tie the wire up, set warning signs.
When there's no fly ash in the silo, 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 should not be exposed
to lighting tools and lines.
In the fly ash silo cleaning process, the number of people outside the
silo should be twice the number of people in it. And professional staff
should be sent to monitor outside the fly ash silo.
After the safety of base stacking and the ladder’s stability have been confirmed, you can enter the silo.
To enter the fly ash silo, the construction workers should wear labor
protective equipment first, including anti-dust masks, goggles, safety
shoes, and safety helmets.
When entering the fly ash silo, the workers have to fasten two safety
ropes, one fixed in the library outside the dust collection device
support, the other fixed on the ladder.
When the cleaning starts, the feed rate of the mill should be based on
the flow; if the flow is too small, put ash in the upper part of the
rotor balance pipe, and put down the fly ash mixed with the mixed
material to do the mixture.
The iron bars and compressed air are used to poke the fly ash to the
bottom of the pool, and then blow out the compressed air at the top of
the silo; after the compressed air is blown out, the long stick is used
to stick the fly ash, and last, use shovel and pick to put it into the
silo. Please notice: people should beware of the falling material and
keep distance from them at the beginning.
If you need high-altitude operation in the fly ash warehouse, you should
strictly abide by the relevant provisions of high-altitude operations.
It is prohibited to use explosives to clean up the fly ash silo.
When the process of coal ash silo cleaning is finished after the
completion of a thorough clean-up, the cleaning work can be over.
