Combustion technologies

=Pulverized Fuel=

=Oxyfuel= Oxy-Fuel consists of combusting pulverized coal in a pure oxygen environment, the advantage of this technology is that exhaust gases are almost 100% CO2 leading to lower transport and storage costs. Oxy-fuel is significantly more complex than regular combustion for coal, it requires the separation of air to obtain a pure oxygen supply, recycling of flue gases and higher temperature equipment. This technology will likely reduce the efficiency of coal plants, increase the cost of coal fired electricity and cause more damage to the environment than current methods of coal production.

=Integrated Gasification Combined Cycle= Coal Gasification is a more efficient process than direct combustion meaning that less coal is required per unit of electricity. Compared to convential coal production, gasification produces about half the solid waste, consumes 20-50% less water and considerably less NOX and SOX emissions. It still requires the capture and storage of CO2. Gasification can be used for electricity production using IGCC, or to produce Hydrogen, or liquid fuels from coal.
