While the coal-based thermal power sector is a significant contributor to India’s energy supply, its operations are associated with substantial environmental concerns, particularly air pollution and greenhouse gas emissions. In 2015, the Ministry of Environment, […]
Coal-based power plants are integral to India’s power sector, supplying over 70 per cent of the country’s electricity despite representing less than half of the total installed capacity. This reliance on coal is projected to […]
Air pollution is a pressing global issue, with particulate matter (PM) and mercury being among the most harmful pollutants affecting public health and the environment. Effective emission control measures are essential to mitigate these impacts, […]
In November 2024, Delhi was once again engulfed in a dense haze of smog, with air quality indices (AQI) breaching hazardous levels, exceeding 400 in several areas. This annual pollution crisis starkly highlights the persistent […]
Emission norms Indian coal typically possesses a high ash content ranging from 35 to 42 per cent, accompanied by an average calorific value of 4000 kcal per kg and an average sulphur content of 0.35 […]
Combustion of coal generates large volumes of nitrogen oxides (NOx), including nitric oxide, nitrogen dioxide and nitrous oxide. The amount of NOx formed depends on combustion conditions and the nitrogen content of the coal. The […]
De-SOx technologies play a crucial role in mitigating sulphur dioxide (SO2) emissions from industrial sources, particularly in coal-based power plants. Among these technologies, wet flue gas desulphurisation (FGD) is one of the most popular and […]
Achieving emission control in coal-based thermal power plants (TPPs) is crucial for facilitating a seamless energy transition. Despite the rapid growth of renewable energy capacity, coal-based plants are anticipated to uphold grid stability in the […]
Thermal power plants (TPPs) are responsible for large volumes of emissions, making the reduction of pollutants such as SOx, NOx and particulate matter a top priority for power plant operators. Overall compliance with the emission […]
In the ever-evolving area of power generation, attention must be given to mitigating the adverse effects of nitrogen oxides (NOx). NOx emissions, stemming from combustion processes within power plant boilers, present a substantial and pressing […]
Particulate matter (PM) emission from thermal power plants (TPPs) is a key contributor to air pollution. Industry estimates suggest that coal-based TPPs contribute 60 per cent of the total PM emitted. These emissions need to […]
A significant proportion of the emissions produced by the industrial sector in the country are attributable to the coal-based thermal power industry. The combustion of coal converts the nitrogen bound in it to products such […]
For coal-fired power plants, several technology solutions are available to meet the SOX emission standards prescribed by the Ministry of Environment, Forest and Climate Change. Wet FGD based on limestone is one of the most […]
Coal-based capacity is the largest contributor to power generation in India with a share of around 70 per cent in 2022-23 (till January 2023). The drawback of the higher share of coal-based power generation capacity […]
Besides sulphur oxides (SOx) and nitrogen oxides (NOx), thermal power plants (TPPs) also emit particulate matter (PM) and mercury. These emissions can be reduced by installing suitable emission controlling devices. Various technologies such as electrostatic […]
Wet flue gas desulphurisation (FGD) systems have been the most popular solution for SOX and NOX emission control, and have been adopted by many thermal power plants (TPPs). More than 90 per cent of TPPs […]
Sulphur dioxide (SO2) emissions are a particularly acute problem in the power sector as well as in the country. SO2 is a corrosive gas created by the oxidation of sulphur bearing materials such as coal, […]
