Coal-based power is the mainstay of the Indian electricity sector, accounting for 55 per cent of the installed power capacity. However, Indian coal has a high ash content of 30-45 per cent, resulting in huge […]
Ash handling technologies help in collecting, conveying, storing and loading different types of residual ash generated by coal-based power plants. The most common types of ash, resulting from the combustion of coal, lignite, wood and […]
The combustion of coal in thermal power plants (TPPs) produces finely divided particles known as fly ash as a by-product. It consists of typically spherical particles of 10-100 microns each. Its primary constituents are oxides […]
Indian coal is characterised by high ash content, which is in the range of 30-45 per cent. During power generation, coal-based power plants in the country generate a huge quantum of ash, which is one […]
Gencos are increasingly looking at technologies and solutions to reduce the environmental impact of coal-based power generation. From emission control equipment to systems for ash handling and disposal, gencos are looking for solutions that offer […]
Coal-based thermal power stations have been operating for decades in India but the concept of developing environment-friendly solutions for fly ash utilisation has picked up in recent years owing to stringent environment regulations. The effective […]
Coal continues to be the mainstay of India’s power generation, accounting for nearly three-fourths of the total power mix in 2018-19. Almost 90 per cent of coal-based capacity in India uses indigenous coal, which has […]
Indian coal has a high ash content of 35-45 per cent and its combustion causes significant air pollution. The practice of surface mining or open cast mining for coal extraction in the country contributes to […]
As per the existing policy framework, coal- and lignite-based power plants are required to ensure 100 per cent fly ash utilisation. In January 2016, the Ministry of Environment, Forest and Climate Change (MoEFCC) had mandated […]
According to the power ministry’s estimates, 1,800 million tonnes (mt) of coal is used every year and 600 mt of fly ash will be generated by 2031-32. Of this, about 40 per cent of the […]
The fly ash produced as a by-product of coal combustion in the boiler poses environmental challenges, and its efficient, sustainable utilisation has been of paramount importance to the power industry. According to latest Central Electricity […]
Almost 40 per cent of ash generated from coal-based power plants is not utilised and ends up in landfill sites as a waste product. Fly ash, which accounts for 80 per cent of the total […]
Effective utilTransitioning to a resource-efficient and circular economy is the key to achieving the country’s sustainable development goals. In line with this, concerted efforts have been made in the power sector to ensure effective utilisation […]
The country’s dependence on coal for meeting its energy needs has resulted in the generation of huge quantities of ash over the years. However, ash utilisation levels have remained dismal. Of the total installed capacity […]
Fly ash management has been one of the key concerns of the power sector in India owing to the high ash content (30-45 per cent) in domestic coal, which accounts for over 70 per cent […]
Indian coal has a high ash content of 30-45 per cent. As per industry estimates, coal-based units ranging from 250 MW to 800 MW produce 100-320 million tonnes of ash per hour. High ash content […]
