Abstract
A tuyere is disclosed with a partition blocking the direct path between the inlet and outlet orifices (16,18) in the main cooling chamber (14). Guide members (30,32) extend from the far side (from the partition) of the orifices (16,18) towards but not reaching the nose-end wall of the cooling chamber (14). Therefore whichever orifice (16,18) is used as the inlet for cooling fluid, a fast moving stream is ensured at the nose end of the chamber (14) near the partition. This assists the cooling of the tuyere in this area, which otherwise tends to form a marked hotspot, especially when the inlet and outlet orifices (16,18) are close together.
