Prayagraj: In a significant discovery that could save vast amounts of fresh water from being used in power generation plants in the country and across the world, a team of scientists led by Professor Ravi Prakash, Department of Mechanical Engineering, Motilal Nehru National Institute of Technology, (MNNIT) has suggested to use sea water instead of river water.
The research work, which has already been published in Springer Journal with the title ‘Energy-Water Nexus for Thermal Power Generation in India: Challenges and Opportunities’, has been cited and highly appreciated in Power magazine published from USA Has been.
The researchers not only detailed the technical challenges facing the country, but also pointed to the opportunities that exist for more sustainable energy production.
The discovery comes at a time when India recently commissioned its first supercritical coal-fired power plant equipped with an air-cooled condenser Energy-water nexus is an important issue for thermal power generation in India, where water Availability is already limited. many areas.
“We have proved that using sea water will not only solve the problem of using water from rivers, but after using sea water to cool the steam, remove the salinity and make it potable Can go”, said. Prof Prakash,
In addition, the system we proposed and analyzed using cold sea water showed high thermal efficiency, free air conditioning, and fresh water and salt as by-products after desalination compared to conventional water- and air-cooled plants. Highlighted several benefits such as production of He used sea water.
Highlighting the study, Jessie MohantaCo-author of the paper and associate professor in the department, said, “It is not feasible to use air-cooled condensers (ACCs) in thermal power plants due to the high cooling load as well as low thermal efficiency of air precooling. Instead seawater By using cooling, there are many benefits including a 27.7% increase in electrical equivalent efficiency, free seawater from the depths of the ocean from the country’s large coastline, providing free air conditioning from the same cooling water (which is about 5) – °C) before going through condensers and can then be desalinated to produce fresh water and salt for the chemical industries.
satyajeet MalodeThe research scholar, who is one of the authors, said, “Investing in more sustainable energy generation is essential not only for India’s future but also for the world’s fight against climate change. He added that seawater cooling-based power plants, as proposed in the cited research, could provide higher thermal efficiencies with the added benefits of free air conditioning and fresh water production.
