Banerjee,Department of Electrical Engineering, IIT Kharagpur. Nishi-Nagoya Thermal Power Station went into commercial operation as an oil-fired power plant in 1970, but along with the aging of its equipment, the Station has been under renewal initiatives to become a highly. specifically for coal fired thermal power plants in India based on the characteristic of coal and operating conditions prevalent at the plant. The efficiency of nuclear plants is little different. power plants accounting for about 40% of the total. Thermal Efficiency "Thermal efficiency" is strictly defined as the useful output energy for a given quantity of gross input heat energy and is therefore subtly different from energy conversion efficiency, which might include both heat and power as inputs and outputs. examine the various factors contributing to the performance of solar power plants, such as radiation, temperature and other climatic conditions, design, inverter efficiency and degradation due to aging. Mahamud, M. Station Heat Rate (SHR) is an important factor to assess the Efficiency of a thermal power station. The losses that develop in the earlier part of the life of a plant are generally containable by employing good operating and maintenance practices. The dust from coal-cleaned water contaminates groundwater. Generally Thermal efficiency of the steam power plant will be in the range of 30-35%. In many industries, steam plants now provide a crucial energy source, delivering reliable high-quality steam for the production process. On the steam turbine side they use the Rankine thermodynamic cycle with steam temperatures at saturated conditions. * efficiency of a power station (Sankey diagram and efficiency calculation). On the 25th February 2008 EFT Stanari signed a concession contract with the Government (Ministry of Economy, Energy and Mining) of the Republic of Srpska. Keywords: DEA; data envelopment analysis; TPP; thermal power plant; scale efficiency; BCC and CCR efficiency. The advanced J-series gas turbine provide thermal efficiency of greater than 63% and produce approximately 65% less CO2 than coal-fired power plants. At the stage of pre-proposals unit of the thermal power plants for regions with a hot climate requires a design study on the efficiency of possible options for the structure of the thermal circuit and a set of key parameters. The article is devoted to reducing the cost of consumption of electric and thermal energy of JSC "Poultry Farm Vasilievskaya". Our study analyses the technical efficiency of coal-based thermal power plants in India to understand any improvement in efficiency due to renovation and modernisation process in the thermal power.
