Consider a coal-fired steam power plant that produces 175 MW of electric power. The power plant operates on a simple ideal Rankine cycle with turbine inlet conditions of 7 MPa and 550°C and a condenser pressure of 15 kPa. The coal has a heating value (energy released when the fuel is burned) of 29,300 kJ/kg.
Natural gas-fired combustion and steam turbines are less efficient and more expensive to run, so they are typically used only during periods of peak electricity demand. Similarly, almost all coal plants (except integrated gasification units, which are rare) combust coal to generate steam, with little opportunity for efficiency improvements.

Many of the lessons learned from the coal-fired power industry are directly applicable to high-pressure heat recovery steam generators (HRSGs), but sometimes the message is not transferred adequately.
In a steam power plant, atmospheric air is fed into the furnace of a steam generator for combustion of fossil fuel (coal, fuel oil, and fuel gas), generating heat released by burning of fuel. Hence, it is essential that fuel is burnt completely in the furnace to release as much heat energy as possible under all operating conditions.

Coal energy electricity works in a similar way to nuclear power and concentrated solar power because coal is a fuel used to heat water into steam to be used in a steam turbine generator. Coal is a fossil fuel, it is found in the ground of the earth and is extracted by mining.
Coal burn time is 4 seconds, which means that a single Coal Generator consumes 15 Coal/min. Pipelines only have a capacity of 300 m 3 /min. Thus, when connecting Water Extractors to a line feeding 7 or more Coal Generators, Water inputs either need to be spaced out or be separated.
