Abstract
The heat recovery boiler (1) is operated, at least temporarily, by feeding its combustion system with air (13) and with a stream (15) of flue gases (4) recycled to a level of at least 45%, typically between 50 and 65%, so as to allow the efficiency of the boiler to be increased and to decouple it, at least temporarily, from the combustion engine (8) driving a generator (9), the exhaust gases from which are burnt in post-combustion mode in the boiler in cogeneration mode.
