How does a jet engine work?

0. The principles for jet airplane engines are same with power generation in natural gas power plants. 

Therefore, to understand jet engines will help us to understand power generation process.

1. How does a jet engine work?

4 stages : Suck -> Squeeze -> Bang -> Blow

2. Turbo jet

Compressed, high pressure, high temperature and high density air can push a turbine really fast and spins it.

3. Turbo fan

Turbo fan uses both fan air and exhaust.

Integrated gasification combined cycle (IGCC)

IGCC :

Solution for traditional coal fired power plant limitations; polution (NOx, SOx) and climate change (CO2).
CO2 capturing : Underground storage facility -> dissolve to water over hundreds of years.
