Week 11 - Thermal Power Engineering

What do Combined Cycle Power Plants use to make electricity?

• Only steam turbines to generate power efficiently

• Wind and solar power to produce renewable energy

• Gas and steam turbines

• Coal and water as primary sources for electricity generation

What does cogeneration produce at the same time?

• Water and gas for industrial and household use

• Electricity and heat to maximize energy efficiency

• Steam and coal for power generation and manufacturing

• Noise and light as byproducts of the energy process

Which material resists heat up to 1000°C in turbines?

• Plastic, which melts at much lower temperatures

• Wood, which burns easily under high temperatures

• Glass, which softens and deforms when heated

• Nickel-based alloy, designed for extreme heat resistance

What is the efficiency of a Combined Cycle Power Plant?

• • 20%

• • 30-40%

• • Up to 60%

• • 100%

What does the Alai CCPP in Almaty use to save fuel?

• Gas and steam together

• Solar panels to generate renewable energy efficiently

• Only coal as the primary source of power generation

• Wind turbines to harness energy from natural air currents
