Without stricter checks, directive to 'utilise' fly ash

Aug 20, 2021 Over the years, with an increase in power generation, India has been seeing an increase in coal ash generation. As the amount of fly ash increased, the environment ministry brought in, as we said, several notifications and amendments to the notifications aiming to achieve 100% utilisation of fly ash within a specified deadline.

Nov 30, 2017 Coal fly ash has a long and successful history of re-use in the US and many other countries in the world. Coal fly ash was recognized as a pozzolanic material (material with cementitious properties when mixed with calcium hydroxide) as early as 1914 and started to be used in concrete in the 1930s (Aggarwal et al., 2010; ARTBA, 2011).

Jul 08, 2021 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.

A-S-H introduces the Hydrovac™ pneumatic vacuum conveying systems for the transport of fly ash to the sluices. A new line of fly ash components is developed to combat the wear of abrasive fly ash moving at high velocities. HYDROVACTOR vacuum producers and steam jet exhausters provided the required vacuum-induced flows.

power plants use bituminous and sub-bituminous coal and produce large quantities of fly ash. High ash content (30% - 50%) coal contributes to these large volumes of fly ash. The country’s dependence on coal for power generation has unchanged. Thus fly ash management is
