Abstract
In a furnace (10) in which a sulfur-bearing fuel is burned, a sorbent material such as limestone is introduced into the upper portion of the furnace through a plurality of nozzle arrangements (40). Each nozzle arrangement comprises a pair of concentric pipes (42,44) with deflector means (46) located between the pipes and adjustable by means (54), so that the sorbent material introduced through the outer pipe is dispersed in an area near the furnace wall, while that introduced through the inner pipe is projected to the central portion of the furnace. There are sufficient nozzle arrangements, and they are so located, so as to cover substantially the entire cross-sectional area of the furnace with sorbent material.
