Abstract

The heat recovery boiler system has an array (1), a bypass (2), and a gas deflector (3, 4). An opening (5) is provided to feed gas and an opening (6) is provided for the removal of the gas. A boiler area is rotational symmetric with the boiler area and arranged concentrically around the bypass and the deflector. A valve is provided to supply the gas in whole or in part. The deflector has a housing with a square cross section of substance and arranged with areas which move.
