New Delhi, Jul 11 (UNI) With an aim to embrace sustainable practices to produce power with minimum emissions, NTPC Ltd, after commissioning India’s first ever Flue Gas Desulphurisation (FGD) unit at Vindhyachal, is implementing this technology across its power plants.
In line with this endeavour for cleaner air and to meet the Government’s deadline of Year 2022 for adhering to the new emission norms, NTPC is already in the process of installing FGD units.
At present, the adoption of this technology is currently at various stages of implementation for 65.35 GW of group capacity in 38 locations which also includes upcoming projects. Once installed across NTPC’s power plants, the FGD unit will facilitate 100 per cent Flue Gas Treatment, thereby limiting the sulphur content to a maximum of 0.49 per cent and achieve 90.6 per cent of SOx removal efficiency.
NTPC has commissioned the country’s first ever FGD technology at the 500 MW unit no. 13 (stage V) unit at its 4760 MW-Vindhyachal power plant in 2017 with a cost of 210 crore rupees. With the focus on curbing release of SOx and other undesirable emissions into the environment, NTPC’s initiative to install this technology has, till date, helped in not only producing power in a sustainable manner but also helped enhance plant efficiency.
In addition to curbing pollution, Wet FGD System in a power plant produces gypsum as a by-product that has at least 90 per cent purity. Since the installation of this technology by NTPC in 2017, its first FGD plant at Vidhyanchal has produced 27,90,400 kg of gypsum with limestone consumption of 42,280 kg.
With sizeable gypsum output, the plant has already dispatched 12, 75,390 kg and 15, 15,010 kg of the mineral to ACC and JP Cement, respectively.
Being an environment conscious organisation, NTPC has further employed measures to utilize agro residue for power generation, thus cutting down stubble burning in fields and bringing down air pollution.
NTPC’s Dadri plant has achieved the distinction of becoming the first plant in the country to commercialize biomass co-firing, with up to 10 per cent of agro residue based bio-fuel co-firing along with coal and plans to replicate the same at all its power stations.
Simultaneously, in line with its commitment towards the environment, NTPC is also installing de-NOx systems based on the emission levels, in compliance with NOx control in coal-fired plants.
A conscientious organisation, NTPC recognises the importance of utilising green technology to help minimise air pollution and is continuously employing measures towards this cause.
