An ash handling system consists of some subsystems such as bottom ash (BA), fly ash (ESP/air heater), ash water, and ash disposal systems. The ash handling system may be dry (dry pneumatic conveying is more popular now on account of retention of original characteristics of fly ash and its utilization), semiautomatic wet, and a wet system.

6. Steel Industry. Rice husk ash is utilized in steel industry to produce high quality flat steel. The rice husk ash is used as insulator due to its desired characteristics such as low thermal conductivity, high melting point, low bulk density, and high porosity. It is used to prevent rapid cooling of the steel and ensure uniform solidification.

research, it has been observed that the use of 30% of fly ash and 70% of cement possess a superior performance. Moreover, in construction, the use of fly ash would result in the reduction of the cost of materials and the reduction of greenhouse gas emission. High strength of concrete can be prepared

the use of fly ash for road construction has also increased phenomenally in India with an annual utilisation of about 8.82 million tonnes in road construction, which constitutes about 16 per cent of total utilisation. Hence use of fly ash for road and embankment construction is thus justifiably called high-volume ash utilisation.

The many benefits of incorporating fly ash into a PCC have been demonstrated through extensive research and countless highway and bridge construction projects. Benefits to concrete vary depending on the type of fly ash, proportion used, other mix ingredients, mixing procedure, field conditions and placement.

Fly ash is a fine powder that is a byproduct of burning pulverized coal in electric generation power plants. Fly ash is a pozzolan, a substance containing aluminous and siliceous material that forms cement in the presence of water. When mixed with lime and water, fly ash forms a compound similar to Portland cement.

• The use of fly ash as a pozzolanic ingredient was recognized as early as 1914, although the earliest noteworthy study of its use was in 1937. • Before its use was lost to the Dark Ages, Roman structures such as aqueducts or the Pantheon in Rome used volcanic ash (which possesses similar properties to fly ash) as pozzolan in their concrete.

produced from these sources. Therefore, huge quantities of fly ash will be available for many years in the future (Malhotra, 2006). The chemical composition and the particle size distribution of the fly ash must be established prior to use. An X-Ray Fluorescence (XRF) analysis may be used to determine the chemical composition of the fly ash.
