Coal-fired boilers are used in many industrial processes, the most prominent being steam generation for utilities and power plant turbines. The primary objective of a boiler is to achieve optimum operating efficiency with high reliability and low cost.
A boiler is called a high pressure boiler when it operates with a steam pressure above 80 bar. The high-pressure boilers are widely used for power generation in thermal power plants. In high-pressure boiler if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.
The modern gas-fired combined cycle plant has a net heat rate of ~7,000 Btu/kWh, the best in the business (based on the lower heating value of natural gas). A standard high-pressure feedwater

A fossil fuel power plant (FFPP) (also known as steam electric power plant in the US , thermal power plant in Asia , or power station in the United Kingdom (UK) is an energy conversion center designed on a large scale for continuous operation. Just as a battery converts relatively small amounts of chemical energy into electricity for temporary or intermittent use, the FFPP converts the energy
A thermal power station is a power plant in which heat energy is converted to electric power.In most of the world the turbine is steam-driven.Water is heated, turns into steam and spins a steam turbine which drives an electrical generator.After it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle.
