Thermal Power Plants and Pollution
Published in T.M. Aggarwal, Environmental Control in Thermal Power Plants, 2021
A thermal power station is a power plant in which the prime mover is steam driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed in a condenser Sameer Kumar et al 568 and recycled to where it was heated; this is known as a Rankine cycle. The greatest variation in the design of thermal power stations is due to the different fossil fuel resources generally used to heat the water. Some prefer to use the term energy center because such facilities convert forms of heat energy into electrical energy. Certain thermal power plants also are designed to produce heat energy for industrial purposes of district heating, or desalination of water, in addition to generating electrical power. Globally, fossil fueled thermal power plants produce a large part of man-made CO2 emissions to the atmosphere, and efforts to reduce these are varied and widespread. The energy efficiency of a conventional thermal power station, considered salable energy produced as a percent of the heating value of the fuel consumed, is typically 33% to 48%.
Burning Magnesium
Published in Takashi Yabe, Tatsuya Yamaji, The Magnesium Civilization, 2010
The construction cost of a thermal power station is enormous, but the magnesium thermal power station does not have this problem. The current thermal power station, using coal or oil, makes steam with the heat of the burnt fuel to turn a turbine that generates electricity. In other words, it is not necessary at all for the existing infrastructure to be changed, and the only thing required is switching the fuel from coal or oil to magnesium. I would like you to know that provided abundant magnesium supply becomes possible, the reduction of the greenhouse gases can be achieved with the existing infrastructure unchanged.

Enhancing use of Renewable Energy is of great importance as many environmental problems can be reduced by replacing fossil fuel. India possesses remarkable scope for generation of Solar Energy. India being tropical country receives year around solar radiation with 2800–3000 sunshine hours (Rachit and Vinod 2016). It receives solar radiation of 4–7 kWh/m2/day. India ranks fifth in world in generation of electricity (Rachit and Vinod 2016). As far as present situation is concerned, India has an installed capacity of 276.783 GW. Out of the total installed capacity 69.6% demand is fulfilled by thermal method, 15.2% from hydro, 2.1% from nuclear while only 13.2% demand of total is fulfilled by non–conventional sources (as on august 2015) (Vikas, Nema, and Baredar 2015). Although 69.6% of total demand is fulfilled by thermal but at the same time it is matter of concern as huge amount of toxin gases like COx, SOx and NOx are being emitted by thermal power station which are detrimental to health. Therefore, there is need to move towards renewable sources of energy for fulfilling our energy demand.
