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 study reported here is aimed at identifying, evaluating and qualifying the materials needed for the construction of the critical components of coal-fired boilers capable of operating with 760 °C (1400 °F)/35 MPa (5000 psi) steam. The economic viability of such a plant has been explored.
the blended coal is used generally in the super critical plants. it reduces loads on the Mills required to break the coal and generally reduces the size of the furnace as well since a larger area will be required to produce the same quantity of heat in case more fuel is required.
An auxiliary boiler is a small package boiler used to supply steam to various processes if the main boiler is not available or not online. The plants I worked in used fuel-oil-fired boilers to provide steam during startups and shutdowns to various systems such as sealing steam, turbine-driven pumps and fans, vacuum jets, etc.
Boiler classification can be based on many factors like usage, fuel fired, fuel firing system, type of arrangement etc. The commonly known types are pulverized coal fired boilers, fluidized bed boilers, super critical boilers, oil and gas fired boilers which all cater to industrial and power generation application.
Each coal-fired plant has stringent water quality permits to ensure local waterways are protected. Duke Energy also carefully manages coal combustion residuals, such as fly ash and gypsum, and looks for opportunities to recycle these into other products to reduce the volume landfilled on site.
Coal Mill In coal-fired power plants coal mills are used to Pulverize and dry the coal before it is blown into The boiler furnace. The coal is fed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to the particles.
