A steam generator and method for operating same in which a plurality of beds of combustible particulate material are established (in A, B, C) and air is introduced (30) to each of the beds for fluidizing the beds. The flue gases and entrained fine particulate material from each bed are combined and the particulate material then separated (in 54) from the flue gases externally of the beds (in A, B, C) and introduced back (by 60) into one of the beds. Independent fluid circuits (80, 82, ...) are established including some in heat exchange relation to the separate beds, for independently controlling the steam generation rate and the temperatures of the reheat steam, and the superheat steam. |
