1. Which part of thermal power plant causes maximum energy losses? Explanation: About 54% of energy losses occurs in condenser.
What are the major causes of efficiency losses in a typical thermal power plant?
The three main factors in determining efficiency are therefore flue-gas exit temperature, excess air and burnout, all of which are dependent on the technology.
Where does the heat loss take place in thermal power plant?
In any thermal power plant the major energy loss takes place in the condenser through its cooling water system.
Which part of Steam Power Station has major heat loss?
In a steam power station, major losses occur in condenser because the conversion from heat energy into mechanical energy is not possible without temperature difference.
Why the thermal efficiency of the steam power plant is quite low?
The overall Steam Turbine Efficiency is quite low (about 29%) due mainly to two reasons. Firstly, a huge amount of heat is lost in the condenser and secondly heat losses occur at various stages of the plant. … The greater the temperature difference, the greater is the heat energy converted into mechanical energy.
What is the maximum thermal power plant conversion efficiency?
Increases in thermal efficiency electrical power generation during past century. … This chemical conversion to electricity can be nearly 100% efficient if the fuel cell device we build has no internal energy losses. Practical fuel cells today have maximum efficiencies over 50%.
Which power plant has highest overall thermal efficiency?
Guinness World Records has named the Chubu Electric Nishi-Nagoya power plant Block-1 in Japan — powered by GE’s 7HA gas turbine — the world’s most efficient combined-cycle power plant, based on achieving 63.08 percent gross efficiency.
Which components of thermal power plant increases the overall efficiency of plant?
The heating of feed water improves the overall efficiency of the plant.
Where is the thermal power plant in India?
A coal based Thermal Power Plants in India the Panipat Thermal Power Station II is located in Panipat in Haryana.

What are the heat losses occur in a boiler plant?
They are the total of two types of losses: Dry Flue Gas Losses – the (sensible) heat energy in the flue gas due to the flue gas temperature; and the Flue Gas Loss Due to Moisture – the (latent) energy in the steam in the flue gas stream due to the water produced by the combustion reaction being vaporized from the high …
Which of the following thermal power plant will have the highest overall thermal efficiency Mcq?
Answer. 3. Which of the following power plant has highest efficiency? (a) Steam power plant.
What is the thermal efficiency of steam power plant?
Efficiency. The efficiency of a conventional steam-electric power plant, defined as energy produced by the plant divided by the heating value of the fuel consumed by it, is typically 33 to 48%, limited as all heat engines are by the laws of thermodynamics (See: Carnot cycle).
Why are cooling towers used in thermal power plant?
A cooling tower serves to dissipate the heat into the atmosphere instead and wind and air diffusion spreads the heat over a much larger area than hot water can distribute heat in a body of water.
What is overall efficiency of thermal power plant in India?
Thermal power plants, backbone of the electricity systems converting heat energy into electrical energy records efficiency between 30 & 50%. Consequently, the balance heat gets dissipated into the atmosphere.
What is thermal efficiency and overall efficiency?
Thermal efficiency relates to processes where the input is thermal energy as in a fired power plant, a internal combustion engine or solar energy systems. … Overall efficiency looks at entire systems from the initial input to the final output. The input does not necessarily have to be thermal in nature.
What is the thermal efficiency of a coal fired power plant?
Typical thermal efficiency for utility-scale electrical generators is around 37% for coal and oil-fired plants, and 56 – 60% (LEV) for combined-cycle gas-fired plants. Plants designed to achieve peak efficiency while operating at capacity will be less efficient when operating off-design (i.e. temperatures too low.)
