How Raw Materials Create Electricty Flashcards
Natural gas
3.2. Environmentally friendly
3.3. Extraction efficiency of natural gas improved due to scientists and engineers perfecting
3.3.1. horizontal drilling
3.3.2. sophistical pressure technieques
3.3.3. to release natural gas from shale formations deep beneath the earth
3.4. Process
3.4.1. Natural gas captured
3.4.2. Natural gas cleaned to remove impurities
3.4.3. Stored in large tanks at distribution center
3.4.4. Gas sent to power plants through pipeline system
3.4.5. To electrical power plants
3.4.6. In boiler natural gas heated
3.4.7. Creates steam
3.4.8. Large Turbines next to boiler
3.4.9. Are powered by the high pressure steam
3.4.10. Propelling giant blades attached to shaft
3.4.11. Spinning shaft at high speeds
3.4.12. Creates mechanical energy
3.4.13. Next Electrical generator converts mechanical energy to electrical energy (electricity)
3.4.14. Spinning a coil of copper wire within a magnetic field
3.4.15. When the coil moves through magnetic field, electrical current is generated
3.4.16. Then electrical current is transferred from power plant to homes/communities and industries
3.4.17. through the electrical grid (a complex system of substations and power lines)
Coal
4.3. COAL EXTRACTION
4.3.1. Extracted from the ground
4.3.2. Through mining two types/methods
4.3.2.1. Underground coal mining
4.3.2.2. Coal surface mining
4.3.3. Method of mining dependent
4.3.3.1. Geology of coal deposit
4.3.3.2. Distance from the surface
4.3.4. Underground mining accounts for larger share of world coal production
4.3.5. Coal burned for
4.3.5.1. HEATING
4.3.5.2. PRODUCE ELECTRICITY
4.4. HOW COAL CREATES ELECTRICITY
4.4.1. Coal first milled into fine powder
4.4.2. Which increases surface area
4.4.3. And allows to burn more quickly
4.4.4. Hot gases and heat energy produced from burning/COMBUSTION of coal
4.4.5. Converts water into STEAM to run turbine an
