Study Notes
Coal Overview
- Used for heating and electricity generation for thousands of years, with significant production growth during the Industrial Revolution in the 18th century.
- Coal-powered steam locomotives became symbols of industrial progress, facilitating transportation and trade.
What is Coal?
- A black or brownish-black sedimentary rock primarily composed of carbon and hydrocarbons.
- Produces energy through combustion, making it a critical fuel source globally.
Heating Fuel
- Continues to serve as a heating fuel despite its controversial status.
- Employed by households for direct heating, particularly in places like Harbin, China.
Coal-Fired Power Plants
- The largest source of electrical energy worldwide.
- Operates by combusting coal to heat water in boilers, producing steam that turns turbines and generates electricity.
- Considered a nonrenewable resource due to its long formation period and limited availability.
Role in Steel Industry
- Essential ingredient in steel production, contributing to industrial infrastructure.
Types of Coal
- Anthracite: Highest rank coal with up to 97% carbon; burns cleaner than other types. Primarily used in stoves and furnaces, expensive due to its purity.
- Bituminous Coal: Formed under significant heat and pressure, containing 45-86% carbon. Commonly used for electricity generation and distinguished by various sub-types, including smithing coal (low ash), cannel coal (historically used for coal oil), and coking coal (for steel production).
- Lignite: Lowest ranked coal, younger (250 million years old), with 25-35% carbon content. Retains high moisture, complicating mining and transport. Mainly used for electricity generation near mining sites.
Coal Formation
- Created from wetland vegetation buried under sediment, undergoing carbonization under heat and pressure to form coal seams.
- Graphite is the final stage of carbonization, utilized in lithium-ion batteries.
Mining Techniques
- Two major coal mining methods: surface mines and underground mines.
- Strip mining, a type of surface mining, removes coal seams located near the surface.
Environmental Impact
- Coal combustion contributes to significant carbon emissions, prompting debates regarding its environmental sustainability.
Global Coal Production
- The U.S. has the largest coal reserves; China leads in anthracite and sub-bituminous coal production, showcasing the global reliance on this fossil fuel.
