Abstract

India is one of the more producer of the electricity in the world. Major source of generation of electricity in India is due to coal. As per National Electricity plan, the government has approved to install 50,025 MW coal based thermal power plants. But, It was observed that more amount of coal is using to generate the electric power than reference level. This was because of presence of magnetic elements in the bed material which was used in boiler to maintain desired temperature at the bottom of the boiler. The efficiency of the boiler is decreasing due to damage caused by the magnetic elements in the bed material. These magnetic elements decrease the reference temperature in the boiler and consequently the boiler operator is allowing excess amount of coal to maintain the reference temperature in the boiler. Because of this, excess amount of coal is used to generate electric power and there by producing excess amount of ash. This can be reduced by constructing a magnetic separator near the bed material stack point and verifying the magnetic elements in the bed material thoroughly. Due to this separator, the boiler efficiency can be maintained nearer to the designed value, usage of excess amount of coal can be reduced. The investment cost for erecting the magnetic separator can be obtained in a couple of years. As a case study, the SKS Power Generation CG Ltd, Raigarh is considered. The proposed theme is applied in MATLAB and the cost of thermal power plant is calculated and existing making data. The obtained results showed that the proposed structure gives a feasible system and best experience and is proved that it is essential for solving such type of assignments.
