Supercritical coal plant Energy Education

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.

Nov 15, 2019 The low calorific value (or high-ash content) in Indian coal reduces the net efficiency of the power plant as compared to low ash content (or high calorific value) coals . One way of increasing net plant efficiency is by adapting advanced power plant technologies such as supercritical (SupC) and ultra-supercritical (Ultra-SupC) plants.

Supercritical steam generator

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 indistinguishable from steam.
