10 top Indian Power plants are highlighted in Power Magazine
The plants were highlighted in June in Power Magazine. Here are the details on the largest’. The Vindhyachal Thermal Power Station in the Singrauli district of Madhya Pradesh, with an installed capacity of 4,760MW, is currently the biggest thermal power plant in India. It is a coal-based power plant owned and operated by NTPC. Construction of the plant, which comprised 12 generating units (six 210MW units and six 500MW units), had begun in 1982. The first unit was commissioned in 1987 while the sixth 500MW was commissioned in April 2013. An additional 500MW unit was commissioned in August 2015, increasing the plant’s gross capacity from 4,260MW to 4,760MW. The plant uses coal from the NCL-operated Nigahi mine and water from the discharge canal of Singrauli Super Thermal Power Station. The turbine manufacturers for the Vindhyachal Thermal Power Station include Russian companies LMZ, Electrosila and the Indian BHEL. The 500MW units were supplied by BHEL.

Older review of India particulate and FGD options
This article is several years old but has some current value. Precip upgrades are needed. For example; NTPC Rihand, whose performance is good (gross efficiency of 36 per cent), is upgrading its 25-year-old ESP to meet PM norms of 50 mg/ Nm3. It is installing advanced moving electrode electrostatic precipitator technology in two fields (the remaining four fields in the middle will remain fixed-electrode type) of the ESP. This technology is expected to reduce emissions from around 400-500 mg/ Nm3 to 50 mg/ Nm3. Relative to FGD Major power equipment manufacturing firms have signed patent agreements for SO2 emission control technologies. Thermax has signed partnership with Marsulex, ISGEC Heavy Engineering Company Pvt Ltd with Amec Foster Wheeler, and Bharat Heavy Electricals Ltd. (BHEL) with Mitsubishi Hitachi etc. Domestic companies like Transparent Technologies Pvt Ltd have developed indigenous technologies for SOx, however, they have limited experience of larger installations, NOx and PM control technology and are mostly indigenous.

Velan was a Major Valve Supplier to Barh
The Velan order for Barh, was worth more than $20 million —it included high-pressure gate, globe, and check valves as well as steam traps and other equipment totaling approximately 4,700 items, plus spares. Six of the 20˝ forged high-pressure gate valves are motor-operated, and they’re in special F91 material for 2900 class service. The plant installed the Velan patented Ultraflex™ wedge valves, an enhanced gate valve with a flexible wedge that is particularly suitable for high-temperature, high-pressure, and severe temperature-pressure cyclic service conditions. This wedge features a novel folded topology that makes it far more flexible than earlier flexible wedge designs of similar proportions, without weakening the wedge blades and detracting from its pressure-retaining function. Velan has supplied the valves to the Russian boiler manufacturer for use in the three 660 megawatt units at Barh.

Wilo supplied Vertical Turbine Pumps for Anpara Power in India in 2014
The Anpara Power Station in India is one of the newest and also largest coal-fired power plants on the Asian continent. To meet the gigantic cooling water demands of this 1,200 MW power station, Wilo developed a special pump type using vertical turbine pumps. In total, five of these massive pumps are used to supply the required cooling water. The pumps’ tasks include the extraction and transport of raw, process, and cooling water, irrigation and drainage, as well as ensuring overflow protection. Each pump has drive power of 3,400 kW and supplies 35,600 m³ of water per hour. These are also the biggest cooling water pumps made of metal ever built in the energy sector in South Asia.

Current and Future Trends in Water and Wastewater Treatment at Power Plants
This is an excellent report prepared by the UK's Department of Trade and Industry providing an assessment of the current state of development and application of water treatment technologies relating to utility and industrial scale fossil fuel-based power generation. Future areas of development are highlighted as well as the current state of the market and its future prospects. The power generation industry is predicted to remain a very significant industrial market for water treatment equipment and associated products. Increases in future global electricity demand are expected to be met primarily through large- scale fossil fuel-based power plants. Coal is projected to retain the largest share of power generation, but with natural gas-fired plants expected to become increasingly important. The main future markets for new fossil power plant are seen as China and India. China represents the largest single market in the world for new power plant equipment currently due to substantial long-term demand for increases in power supply. Coal is the main source of fuel for power generation in China and natural reserves are extensive. The use of coal is expected to grow substantially up to 2030, with the installation of new large-scale boiler plants. China is pursuing Clean Coal Technologies as a means of meeting future energy requirements, with supercritical boilers and Integrated Gasification Technology being attractive options. The power sector in India is dominated by coal and use is projected to increase threefold from 2000 to 2030. Ultraviolet technology along with ozone is sited as an emerging and novel treatment technology. There has been an increase in the use of UV technology as it eliminates the problems associated with the addition of chemicals with respect to factors such as disinfection by-product formation, safety factors in handling and storage, and economic factors. The use of UV radiation in conjunction with ozone or hydrogen peroxide can further enhance the efficacy of the overall disinfection process. Worldwide, with increasing limitations on clean water supplies and increasingly stringent environmental legislation, it is expected there will be a greater need to treat alternative low- quality water supplies. The successful application of these advanced technologies for treating such waters will be ever more important for future fossil fuel power generation.
