Water Reduction Potential in Thermal Power Plant in India
Abstract
Water & Coal are the blood & food of a thermal power plant. As like without water & food a human being can’t alive, similarly without water and coal, anybody cannot imagine a thermal power plant or without water & Coal power plant can’t produce electricity. As much as needed in modern life without electricity anybody can’t be imagination of a piece full life. Water is the essential requirements for thermal power plants. Water is used in Boiler for Steam generation, in cooling towers as a coolant. As we all know whole world is suffering, the shortage of fresh water for drinking & utilization of human being. Huge quantity of fresh water is required for power generation in thermal power plant. The current water consumption in Indian coal based thermal power plant is around 1100 million m3, which is much higher than our neighbor country China. Which has power generation capacity is around 2.5 times then India. In Indian power industries have huge potential to reduce Fresh water consumption by adopting new techniques or by modifying the current techniques with minor changes. 90% of water consumption in thermal power plant as in the form of Evaporation in Cooling towers. It can be reduce by adopting some techniques such as.
By increasing C.O.C of circulating water
By decreasing blow down with modification
By decreasing drift losses
Modified chemical treatment programs
By adopting Air Cooled Condenser techniques instead of Wet Cooling Towers.
By adopting hybrid C.T.
By recycling & reuse of Blow down water
My study is about to develop the techniques to reduce water consumption in Thermal power plants in India. This study give the direct benefits to power industries for reducing their power generation cost, by decreasing fresh water requirements, and indirect benefits like reduction in auxiliary power consumption in Cooling water pumping, m/up water pumping & reduction cooling m/up water chemical pretreatment cost.
Biography: My self Pawan Kumar, I am a research scholar in Dept. of Chemistry in SUNRISE University, Alwar, state Rajasthan from January 2020. I am doing research in water conservation scope in thermal power plant in India.
