Emission Control

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 […]

While burning coal in the boiler, coal-based thermal power plan­ts (TPPs) convert a large portion of nitrogen in the coal to various forms of nitrogen oxide (NOx) such as nitric oxide, nitrogen dioxide and nitrous […]

Emission control from coal-based thermal po­wer plants (TPPs) is the key to facilitating a sm­ooth energy transition in India. Renewable energy ca­pa­city is growing at a rapid rate and coal-based plants are expec­ted to play […]

Coal-based capacity is the largest contributor to power generation in India with a share of 71 per cent in 2020-21. The drawback of the higher share of coal-based power generation ca­pa­city is the emission of […]

De-sulphur oxide (SOx) solutions are imperative for coal-based power plants to comply with the Ministry of Environment, Forest and Climate Change’s environmental norms prescribed for thermal power plants (TPPs). While several technology solutions are av­ailable […]

Coal-fired thermal power plants (TPPs) account for a significant amount of the country’s greenhou­se gas emissions, contributing to pollution and poor air quality. The combustion process in TPPs converts some of the nitrogen bound in […]

Thermal power plants (TPPs) utilise significant amount of fresh water during power generation for con­den­ser cooling, removal of plant heat from plant auxiliaries and cycle make-up. Currently, TPPs in India account for less than 5 […]
