ABSTRACT:
A pressurized boiler assembly (e.g. with a circulating fluidized bed combustion chamber), including a pressure vessel pressurized to about 7-30 bar, has a minimum height, minimum number of through extending openings in the pressure vessel, and maximum accessibility to the controls and adjustments for the boiler. A steam drum is mounted by a flange joint above the boiler so that it extends horizontally, with the main body of the steam drum with the pressure vessel, but with a first end of the steam drum exteriorly of the vessel. The control and adjustment elements for the boiler, such as safety valves, pressure indicators, and water gauges, are mounted to the first end of the steam drum, exteriorly of the pressure vessel. A superheater having a discharge conduit is also mounted within the vessel below the steam drum, and the first end of the steam drum and the superheater discharge conduit are essentially the only elements associated with the boiler water and steam system passing through the pressure vessel.
