Air Boiler revamped to Oxy Boiler:• Air Liquide has developped and built 4 oxy-burners (8MWth each)• Alstom has revamped the boiler – Major modification was the

installation of a Flue Gas Recycleinstallation of a Flue Gas Recycle• Oxy-boiler produces 40 tonnes/hour of steam 60b/450°C (30MWth)

which feeds the HP steam network of the Lacq plant

Cooling of flue gases:
