Abstract
A fluidized bed boiler having a water-wall type construction has a steam-water natural circulation system for heat exchange. Vertical in-bed heat exchange tubes are provided and the steam drum of the boiler extends across the full length of the boiler combustion chamber and the convection heat exchange chamber. An air distributor grate is provided for introduction of fluidizing air into the combustion chamber and the air flow therefrom can be controlled to afford a flexible turn-down capability.
