In a fossil fuel power plant the chemical energy stored in fossil fuels such as coal, fuel oil, natural gas or oil shale and oxygen of the air converted successively into thermal energy, mechanical energy and, finally, electrical energy. now assume that a coal-fired plant with a capacity of 100 MW uses coal as an energy source to produce heat which later converted to electrical energy with 60% efficiency (40% is lost as heat). The total heat of coal is given 6000 kcal/kg. The combustion temperature for steam is 100-celsius degrees. The cooling water is provided from a river with an ambient temperature of 25 Celcius degrees. The power plant operates 24 hours per day. Based on the information given in the problem, Calculate; a) How many tons of coal should be used in this power plant? b) What is the Daily amount of DI water for the production of steam? c) What is the Daily amount of cooling water for condensation?
