Babcock-Hitachi K.K. and FORTUM have jointly studied the feasibility of retrofitting a power plant with an oxy-fuel combustion system for capturing carbon dioxide. Combustion and heat transfer characteristics in oxy-fuel combustion have been compared with those in air-combustion by using HT-NR burners at 4.0 MWth single burner tests. Results were as follows: (1) The flame stability was very satisfactory using a HT-NR3 burner at the period of changing from air combustion to oxy-fuel combustion and oxy-fuel combustion, (2) The minimum Primary O_2 limitation of NR-LE could be reduced to 10%-wet without any combustion problem because of higher flame stability. (3) The radiation heat flux of oxy-fuel combustion was almost same as one of air combustion at 28vol% of inlet O_2 concentration (wet base).
