Abstract

A heat-recovery boiler (1) for generating steam from a flow (A) of hot gases, which enables high efficiency to be achieved in combined cycles, includes a supply manifold (2) for supplying the flow (A) to a chamber (10) which houses a plurality of tube nests (11) for water and/or steam and a branch (3) in the supply manifold (2) which defines a first hot gas duct (4) connected directly to the chamber (10) and a second hot gas duct (5) which houses a burner (20) for the post-combustion of poor combustible gas with part of the flow of hot gases. <IMAGE>
