Abstract

A tuyere for use in furnaces having a base section attached to the wall of the furnace and a nose section that extends into the interior of the furnace. The nose section includes an angled or sloped top surface and may include two front side faces that taper inwardly to facilitate passage of the coke or other materials past the tuyere during operation. A passageway extending through the tuyere to introduce air into the interior of the furnace may include multiple sections with the outlet section having a downward angle to prevent air from bouncing back toward the tuyere. In a second embodiment, the tuyere may have a base plate that is attached to the furnace to allow the nose section to be slidingly attached thereto.
