system design and analysis of a supercritical thermal power plant.
Supercritical coal plants are a type of coal-fired power plant used in more modern designs. They differ from traditional coal power plants because the water running through it works as a supercritical fluid, meaning it is neither a liquid or a gas.This occurs when water reaches its critical point under high pressures and temperatures, specifically at 22 MPa and 374 o C.

The power plant's net efficiency is simply the heat content of electricity (3600 kJ/kWh) divided by the heat rate (kJ/kWh) (see Equation 2). (2) The power plant's heat rate depends on the fuel type used and the specific power plant design. All the heat put into the plant that is not converted into electricity has to be dissipated somehow to the
Jun 28, 2017· If the plant uses ultra-supercritical technology, it needs thermal input of 1000 MW / 44 per cent = 2270 MW-thermal. As a result, it burns 350 tonnes of coal per hour, or 14 per cent less than the subcritical plant and generates 14 per cent less SO2. If the plant is not equipped with SO2 emission control technology, that's the end of the story.

India has huge coal reserves, about 7.1 per cent of the world's total  and thus the coal-based thermal power plants dominate the sourcewise mix with 54.1 per cent of the total installed capacity of about 174 GWe .Due to the energy shortage of 8.5 per cent , a large number of old coal-fired units are still in use, operating on much lower plant efficiencies compared with their design …
A supercritical steam generator is a type of boiler that operates at supercritical pressure, frequently used in the production of electric power.. In contrast to a subcritical boiler in which bubbles can form, a supercritical steam generator operates at pressures above the critical pressure – 22 megapascals (3,200 psi).Therefore, liquid water immediately becomes steam.
These are Supercritical power plants. The operating pressures are in the range of 230 to 265 bar. The efficiency of the Rankine cycle depends on the pressure at which it operates. Higher pressure and temperature increase the efficiency of the thermal cycle and power plant. This is the reason for operating at higher steam pressures. Ultra ...

If the system is operated only with natural/assisted circulation, the application range is limited to a max drum pressure of approx. 190 bar. If a circulating pump is used (forced circulation), this range can be extended somewhat fixing the endpoint of evaporation in the drum also sets the size of the heating surface in the evaporator & superheater.
