COMBUSTION TECHNOLOGY
Combustion technology is improvements to the combustion
equipment and the overall combustion process. One promising technique replaces
air fed to the combustion process with pure oxygen supply. The first step in
this process is to extract the oxygen from the incoming air supply. This is
normally accomplished through cryogenics, which consumes almost 15% of
electricity generated by the unit. The combustion exhaust stream consists of
predominantly carbon dioxide and water vapor. On cooling, the water vapor
condenses and separates from carbon dioxide gas which can then be stored.
Features
- A new technology called Chemical Looping Combustion (CLC) may simplify
oxygen extraction from air.
- Improving burner and boiler efficiencies lead to an increase in overall
combustion efficiency.
Advantages
- Highest carbon capture possibility (100%).
- Complete combustion due to pure oxygen supply results in minimal noxious
emissions.
- Possibility for retro-fitting existing burners to operate with pure oxygen.
Disadvantages
- Current technology has not been demonstrated at commercial scale.
- High energy penalty for use of oxygen fuel without CLC.
