Bharat Heavy Electricals Ltd (BHEL) has achieved a significant milestone in the ‘Make in India’ initiative by successfully producing the first batch of domestic SCR Catalysts. These Selective Catalyst Reactors (SCR) were previously imported, but BHEL has now established a manufacturing facility for SCR catalysts at its SBD unit. This move is aimed at addressing NOx emissions in thermal power plants.
The burning of coal in power plants results in the conversion of nitrogen present in coal into various nitrogen oxide compounds, including nitric oxide (NO), nitrogen dioxide (NO2), and nitrous oxide (N2O). Collectively, these compounds are referred to as nitrogen oxides (NOx), which are a significant air pollutant.
In response to the Ministry of Environment and Forest’s concerns about the long-term adverse effects of NOx emissions, several power companies, including Telangana State Power Generation Corporation Limited (TSGENCO) for the 5×800 MW Yadadri thermal power station, Maharashtra State Power Generation Co Ltd (MAHAGENCO) for the 1×660 MW Bhusawal thermal power station, West Bengal Power Development Corporation Limited (WBPDCL) for the 1×660 MW Sagardighi thermal power station, and NALCO for the 1×18.5 MW Damanjodi thermal power station, have placed orders for SCR systems.
As reported by Outlook, BHEL is dedicated to environmental protection and offers a comprehensive range of eco-friendly technologies for thermal power plants. This includes high-efficiency boilers, electrostatic precipitators, flue gas desulphurization units, and selective catalyst reactors. The technology for these systems has been indigenized by BHEL, building on expertise absorbed from the market leader, NANO, Republic of Korea.
