Emission Economics: Costs and benefits of installing FGD systems

November 13, 2021

A flue-gas desulphurisation (FGD) system is installed in the boiler of a thermal power plant (TPP) to abso­rb the sulphur content from the emissions, thereby reducing sulphur dioxide (SOx) emissions. The cost economics of FGD […]

Emission Control

De-NOX Solutions: Combustion modification and advanced control procedures

November 11, 2021

In thermal power plants (TPPs), the combustion of coal converts a large portion of the nitrogen bound in coal to form oxides of nitrogen (NOX) such as nitric oxide, nitrogen dioxide and nitro­us oxide. The […]

Emission Check: Technologies for particulate matter and mercury control in TPPs

November 9, 2021

The particulate matter (PM) emissions in a thermal power plant (TPP) can be reduced and controlled by the installation of emission controlling devices such as electrostatic precipitators (ESPs), fabric filters and cyclone se­p­arators. Empirical data […]

Controlling Discharge: Water management and consumption

November 8, 2021

Among the industrial consumers of water, thermal power plants (TPPs) are the largest ones. It is estimated that TPPs account for nearly 88 per cent of industrial water consumption in the country. Moreover, 48 per […]

Meeting Emission Norms: Recent developments and challenges in the deployment of FGDs

October 10, 2020

Compliance with the revised emission norms issued by the environment ministry in December 2015 remains tardy, and the industry has been seeking an extension to the 2022 deadline. The Ministry of Power (MoP) recently wrote […]

Emission Control

FGD Update: Implementation status, key issues and regulatory changes

October 9, 2020

In December 2015, the Ministry of Environment, Forest and Climate Change (MoEF&CC) notified emission norms for coal-based power plants. The sulphur oxide (Sox) emission limit for thermal power plants (TPPs) installed up to December 31, […]

Emission Control

Controlling NOx: Need to implement advanced technologies to reduce emissions

October 8, 2020

The coal-based thermal power industry is responsible for a significant share of emissions by the country’s industrial sector. The combustion of coal converts nitrogen bound in coal to form products such as nitric oxide (NO), […]

Emission Control

PM Curbs: Emission control norms and technologies

October 7, 2020

In order to minimise the harmful impact of emissions, the thermal power industry is now increasingly using particulate matter (PM) control equipment and technologies, which are designed to remove particulates from the flue gas stream, […]

Emission Control

Water Stress: Efforts to reduce and regulate consumption by TPPs

October 6, 2020

  Thermal power plants (TPPs) are among the largest industrial consumers of water. Among TPPs, coal-based power plants are the biggest consumers. As of August 2020, India has about 269 TPPs. According to a study by […]

Compliance Status: Update on adherence to emission norms by TPPs

October 6, 2019

The Ministry of Environment, Forest and Climate Change (MOEF&CC) notified new emission norms for thermal power plants (TPPs) in December 2015 with an objective to reduce the emission of major pollutants such as particulate matter […]

Emission Control

Retrofitting TPPs: Focus on FGD implementation to meet SOx norms

October 5, 2019

India is the largest emitter of sulphur dioxide (SO2) in the world. SO2 emissions are a significant contributor to air pollution. The largest sources of SO2 are thermal power plants (TPPs) and other industrial facilities […]

Emission Control

NOx Reduction Initiatives: TPPs need advanced control technologies to achieve desired levels

October 4, 2019

The environmental norms notified by the Ministry of Environment, Forest and Climate Change in December 2015 have prescribed the nitrogen oxides (NOx) emission norms for thermal power plants (TPPs) in the country. Prior to this, […]

Emission Control

ESP Upgradation: Efforts to meet emission control norms

October 3, 2019

Thermal power stations emit significant amounts of fly ash and ultra-fine particles into the atmosphere. Electrostatic precipitators (ESPs) help remove fly ash and fine particles from flue gas before passing the gas into the chimney. […]

Emission Control

Prudent Use: Reducing specific water consumption at TPPs

October 2, 2019

With nearly 87.8 per cent of the total industrial water being used in thermal power plants (TPPs) for power generation, concerns of India becoming a water-stressed country are growing. Water plays a significant role in […]

Reducing SOx Emissions: Progress in FGD implementation towards meeting the 2022 target

October 19, 2018

Flue gas desulphurisation (FGD) is one of the key technology solutions used at thermal power plants (TPPs) to cut down emissions. It helps in reducing suspended particulate matter (SPM) emissions along with sulphur oxide (SOx) […]
