Applicability and potential
・・・・Applicable for existing and new-installed power plants
・・・・Potential for the reduction of cost and power
consumption by scaling-up of ASU and the integration of
total process
Process・・・・Installation of air separation unit
・・・・Flame temperature is adjusted by flue gas
recirculation
・・・・NOx emission is reduced by flue gas
recirculation
・・・・DeNOx and DeSOx will be compacted in case of
new-installed power plant
Feature
・・・・CO2 is major component in the flue gas
・・・・Amount of flue gas to CO2 purification can be reduced
to be almost one forth
CO2 capture using CO2 capture using CO2 capture using CO2 capture using oxyfueloxyfueloxyfueloxyfuel
Oxyfuel combustion ;
In coal fired power plant, coal combustion by oxygen in stead of air make it possible
to be concentrated of CO2 more than 90% theoretically in the flue gas.
