Coal Fired Boiler

Definition

A coal-fired boiler is a pressure vessel that generates steam by burning coal. This steam powers a steam turbine, which spins a generator to supply electricity to the power grid, eventually reaching homes and businesses.

Purpose

The purpose of a coal-fired boiler is to convert the potential energy stored in coal into electrical energy. This process involves burning coal to produce high-pressure steam, which drives a turbine connected to an electricity generator.

Examples of Use

• Coal-fired power plants use large coal-fired boilers to generate electricity for regional grids.
• Industrial facilities may use smaller coal-fired boilers to generate steam for manufacturing processes.
• Historically, steam locomotives used coal-fired boilers to generate the steam needed to power the engines.

Related Terms

• Steam Turbine: A device that converts steam energy into mechanical energy to drive a generator.
• Generator: A machine that converts mechanical energy into electrical energy.
• Fossil Fuel: A natural fuel such as coal, oil, or natural gas formed from the remains of living organisms.

Notes

Coal-fired boilers are being phased out in many regions due to environmental concerns, as they are significant sources of greenhouse gas emissions and air pollutants.
