Mr.D.D.JOSHI RANJEET PADOL
-Fly ash is a waste material from thermal power
- which forces a great disposal
Problem besides causing atmospheric
-India’s 82 utility and more than 25 captive thermal
power plants contribute more than 70 Percent to the
countries total electric power installed capacity
(approx 100,000 MW). In fact about 240 million
tonnes of coal is being used every year to generate
Fly ash is defined as “A finely divided residue that results from
the combustion of ground or powdered coal and is transported
from the combustion chamber by exhaust gases”.
CHEMICAL COMPOSITION OF INDIAN FLY ASH-
-Silica (SiO2) 49-67
-Alumina (Al2O3) 16-29
-Iron Oxide (Fe2O3) 4-10
-Calcium Oxide (CaO) 1-4
-Magnesium Oxide (MgO) 0.2-2
-Sulphur (SO3) 0.1-2
-Loss of Ignition 0.5.3.0
USES OF FLYASH:
- FLY ASH AS WOOD SUBSTITUTE MATERIAL
- FLY ASH CELLULAR CONCRETE
- FLY ASH IS A BUILDING MATERIAL
- FLY ASH EMULSION PAINTS /BUILDING DISTEMPERS:
- FLY ASH CLAY BRICKS
- HOLLOW BLOCKS
- FLY ASH LIGHT AGGREGATE
- USE AS PART REPLACEMENT OF CEMENT / MANUFACTURE OF CEMENT:
FLY ASH AS WOOD SUBSTITUTE MATERIAL:
A very good wood substitute for doors,
windows, ceiling, partitions, furniture, etc.
-Environment friendly technology.
-Fruitful utilization of industrial wastes such as fly ash.
-Energy efficient production technology.
-Products stronger than woods.
-Weather resistant and durable.
-Termite, Fungus, rot and rodent resistant.
-Cheaper than natural wood.
-Less maintenance cost.
PLANT DETAILS :
-12000 m2 doors/panels per annum (8 hours shift)
SIZE OF PRODUCTION:
-Doors:2100 x 900 x 25-30 mm or any other size
-Panels:1800 x 900 x (3-25)63
ENVIRONMENTAL IMPACTS OF FLYASH:
HEALTH ASPECTS OF COAL FLY ASH:
- THROAT PROBLEM
- LUNGS DISEASES
- RASHES ON WORKER BODY
EFFECT OF FLY ASH IN AGRICULTURE:
i) Modification of soil texture-ii)
Modification of bulk density-iii)
Water holding capacity of soil-iv)
Effect on soil crust-
The future poses challenges to the scientists,
technologists, engineers towards sound management of
fly ash disposal & deposition technologies. The problem
is not due to lack of technical competence but more of
adoption, implementation and better management of
improved & appropriate technologies.
