Search for: Engineering 2022 , FAQs Interview Questions , compared to the rate at which generation capacity increase. Boiler is a heart of power plant, so its efficiency is directly affected to the all over efficiency of the plant. It is quite obvious that approximately 65% to 70% power generation comes out from Thermal Power Plant uses Coal as fuel available from various parts of India, where Abstract: This paper presents briefly on the boiler efficiency evaluation procedures by direct and indirect methods useful in thermal power plants. In the direct method consideration is given to the amount of heat utilized while evaluating the efficiency of the boiler, whereas, indirect method accounts for various heat losses. Rodrigo Soto has proposed a theory that, when effective, could enhance the efficiency of coastal thermal power plants by about 25-37 MW without any added emissions, simultaneously reducing water temperature and desalinating about 5.8 M tons of water per year. Currently, sub-critical thermal power plants can attain an efficiency of around 38%, compared with 41% by supercritical thermal power plants, while ultra-supercritical thermal power plants can reach up to around 44%. The main components that affect the efficiency of thermal power plants include boiler, turbine, and generator. In this work, the new concept of solar thermal power plant system considered in which efficiency of this novel model is obtained which quite greater than stand-alone operation of solar thermal power plant. The efficiency of STPP in standalone operation (solar to electrical efficiency) is 16.7%. The overall efficiency of a thermal power station is low (less than 30%). Requires long time for errection and put into action. Costlier in operating in comparison with that of Hydro and Nuclear power plants. Requirement of water in huge quantity. The efficiency of a plant is the percentage of the total energy content of a power plant 's fuel that is converted into electricity. The remaining energy is usually lost to the environment as heat unless it is used for district heating . Rating efficiency is complicated by the fact that there are two different ways to measure the fuel energy The digital twin technology-based turbine rotor automation monitoring model for thermal power plants is shown in Figure 1. The architecture mainly consists of four parts: physical entity layer, virtual model layer, twin data layer, and application service layer, and the information interaction is realized through the connection between each layer.
