Abstract

1. A fluidised bed combustion chamber of variable heat output, delimited by a side wall (1) surrounding a central zone (6) and a fluidisation grid (2), in which the fluidised bed has a lower level (13) at the lowest output of the combustion chamber and an upper level (14) at the highest output of the combustion chamber, containing a tubular heat exchanger having tubes (7, 8) which extend in a vertical direction at least between the lower level (13) and the upper level (14) characterised in that injectors (12) for injecting air for confining the combustion zone are disposed above the upper level (14) in the vicinity of the side wall (1) and are directed towards the central zone (6) of the combustion chamber with an inclination relative to the vertical at an angle (a) of between 15 degrees and 75 degrees, the total flow rate of the confinement air injected by said injectors (12) being controllable at between 5% and 20% of the total flow rate of the air introduced into the combustion chamber.
