General
- Fly ash
(also known as a coal combustion product, or CCP) is the finely
divided mineral residue resulting from the combustion of powdered
coal in electric generating plants.
- Fly ash
consists of inorganic, incombustible matter present in the coal that
has been fused during combustion into a glassy, amorphous structure.
It is also called pulverized fuel ash.
- Optimum reuse of
fly ash can be achieved if the chemical and physical nature of the
ash is known, thus allowing its end use to be engineered to the
proper end state.
Production
- The fly ash
produced from the burning of pulverized coal in a coal-fired boiler
is a fine-grained, powdery particulate material that is carried off
in the flue gas and usually collected from the flue gas by means of
electrostatic precipitators, baghouses, or mechanical collection
devices such as cyclones.
- Close to 80% of
the total pulverised fuel ash are produced iduring combustion
process.
- Pneumatic
conveying offers an ideal choice for dry handling of flyash.
- Fly ash collected
in dry form is of more value than when collected in wet form.
Application
- Dry fly ash is
good for pozzolanic and ceramic applications, where as bottom ash is
good for use as fine aggregate.
- When fly ash is
used as supplementary cementitious material (SCM) in the manufacture
of concrete, some of the GHG emissions from cement production are
avoided.
- The allocation of
emission benefits associated with the use of fly ash presents new
territory for commodities trading.
Technology
- Fly ash
technology is providing relief to the overstressed resource base of
soils being mined for the production of fired-bricks. This is
demonstrated in the post-tsunami reconstruction project in South
India.
- Our electrostatic
technology processes high carbon fly ash to make it usable in
concrete. This technology has many business advantages for power
plants, since it is the most flexible, cleanest, fly ash processing
solution, with the longest record of proven commercial success.
Market
- The importance of
this techno-market survey on flyash prefabrication is directly
related to a number of factors which are important to our country
and the rest of the world as a whole.
- The
slag-tap boiler burns pulverized coal and produces 50% slag and 50%
fly ash. The cyclone boiler burns crushed coal and produces 70-80%
slag and 20-30% fly ash.
