ABSTRACT:
A fluidized bed apparatus (1) having a fluidization grid (2) below which is positioned a tuyere (5) for guiding fluidization gas to the fluidization grid (2). The tuyere (5) comprises a widening pipe the wider end (6) of which is positioned towards the fluidization grid (2) and has an area which is substantially the same as the cross-sectional area of the fluidized bed apparatus (1) and is 2 to 30 times that of the area of the narrower end (7) of the widening pipe. The process for feeding fluidization gas to a fluidized bed using such apparatus enables a good gas distribution across the bed to be achieved with a modest additional pressure drop. The invention is particularly useful for apparatus e.g. greater than 3 m in diameter.
