The Indian government's pollution watchdog has proposed new guidelines to steer decommissioning of coalbased power plants in the country, suggesting a range of measures including an Environmental Management Plan (EMP) and an Environmental Impact Assessment (EIA) report for the decommissioning process.. The draft guidelines were prepared by the Central Pollution Control Board (CPCB ...
Section snippets Methodology. In order to analyze the environmental impact in different scenarios of electric power generation plants with the coupling of a CO 2 capture process in postcombustion, two cases were studied: constant fuel flow and constant energy demand. For each of these cases, four different fuels were used: biogas, coal, nonassociated gas, and associated gas.
India is the second largest coal producer and importer, after China. Coal India, the national coal mining company and largest coal producer in the world, accounts for around 84% of domestic output. India has proven coal reserves of around 98bn tonnes, or % of the world total, again second only to China.
Most countries, including India, have plans to phase out coal over the next few decades. India, in fact, has officially announced that it would not set up any new coalfired power plants after 2022. However, we still have to live with coal for some more time at least. In spite of the rapid increase in power generation from renewable sources ...
Both fossil and renewable fuel sources are used widely to produce electricity around the globe. The dependency on fossil fuels for energy leads to the depletion of reserves and various forms of pollution.

Coal fired power plants also known as coal fired power stations are facilities that burn coal to make steam in order to generate electricity. These stations, seen in Figure 1, provide ~40% of the world's electricity. [2] Countries such as South Africa use coal for 94% of their electricity and China and India use coal for 7075% of their ...
To date, DOE has not adopted environmental emission goals for coal liquefaction process plants, as it has for electric power plants. Future plants will likely have to meet air, land, and water emission requirements that are more stringent than those in place today, which could increase the overall cost of coal conversion processes relative to ...
"In Australia, coal use is invariably on the way out, as renewable energy is now the cheaper way of producing electricity from new plants, and Australia's coal power plant fleet is relatively old ...
Presently, Carbon Capture and Storage (CCS) act as a bridging technology and a viable option for coal fired power plants to extract CO 2. But, still in India the adoption of CCS in coal fired power plant is poor. In UNFCCCs Paris Summit, India committed to reduce its carbon intensity by 30%33% by 2030. The present study deals with the ...
The International Energy Agency (IEA) estimates that coalfired power plants in India can increase thermal efficiency by up to 10 percentage points by switching from unwashed to washed coal . China also expects to make greater use of coal preparation technology to improve thermal efficiencies and environmental performance [ 15 ].
The move had come a year after the Glasglow climate meeting had decided to call for a phasedown of "unabated" use of coal. More than 50 per cent of India's electricity generation comes from coalfired power plants, and India has maintained that coal will continue to remain the mainstay of India's electricity sector for some more years ...
Coal oil was used primarily as fuel for streetlights and other illumination. The widespread use of kerosene reduced the use of coal oil in the 20th century. Coking coal is used in largescale industrial processes. The coal is coked, a process of heating the rock in the absense of oxygen. This reduces the moisture content and makes it a more ...
The rest was produced under 'captive' mining licences for individual industrial use. Coal from the new mining licences, however, can be sold on the open market. Modi has said India will spend INR500bn ( billion) "for creating infrastructures around coal mining," adding the country was targeting gasification of 100mt of coal by 2030.
The United States generates 2% of its electricity from biomass and waste energy. 2. Spain generates 17% of its electricity with wind power. 3. Paraguay generates of its electricity from hydropower. 4. South Korea has one of the biggest tidal power plants in the world. 5.
Thermal power plants generate electricity with the help of fuels. Thermal power generation is the process of burning oil, liquid natural gas (LNG), coal, and other substances to generate steam power that rotates generators and produces electricity. This type of generation plays a vital role in supplying electricity because it can be adapted to ...

The chemical composition of fly ash varies from one coal thermal power plant to another and depend upon geological factors associated with coal formation and the operating procedures (Bhangare et al., 2011).Coal ash is mainly composed of Si, Al, Ca, K, etc. and may contain toxic elements such as lead (Pb), zinc (Zn), cadmium (Cd), nickel (Ni), arsenic (As), mercury (Hg) and cobalt (Co) namely ...
Coal is an abundant natural resource that can be used as a source of energy, as a chemical source from which numerous synthetic compounds (, dyes, oils, waxes, pharmaceuticals, and pesticides) can be derived, and in the production of coke for metallurgical processes. Coal is a major source of energy in the production of electrical power ...
The Indian government wants to ramp up the country's coal production and consumption. In line with this goal, the union environment ministry has now made it easier for thermal power plants to change the source of coal from imported to domestic a procedure that so far involved seeking an amendment in the environment clearance that such plants already had.
So, in summary it can be said that gasificationbased power offers efficiency benefits in the use of water. Raw water use in IGCC plants is lower than in pulverized coal plants. Without CCS, PC plants have a much higher steam turbine output, requiring more cooling water and condenser duties (typical raw water use ratio of :).
Monitoring and enforcing the performance of equipment in coalbased thermal power plants play a vital role in operational management. As the coalbased power plant is a nonlinear system involving multiple inputs and multiple outputs, the standard and typical identification methods tend to deviate. This can happen due to factors such as strong coupling, multivariable characteristics, time ...
It also has health benefits due mainly to the lower quantity of coal burned per energy generated as well as to small reductions in the sulfur content of coal burned.
