Abstract
A combined nozzle for air and fuel to a fluidized bed (20) comprises two fixed portions (1, 10) mounted at the top and bottom of an air chamber (4) and a movable, withdrawable portion (2) which connects the two fixed portions and is guided by them. The movable portion blocks the lower fixed portion (10) outwardly and conducts air and fuel to the upper fixed portion (1). Further, there is a device (3, 26) for sealing the lower fixed portion when the movable portion is removed for inspection during operation. (FIG. 2).
