Injection Lance With Variable Swirl

View page
US Patent:
20130146680, Jun 13, 2013
Filed:
Dec 9, 2011
Appl. No.:
13/315633
Inventors:
Pavan Kumar SHIVARAM - Pittsburgh PA, US
Assignee:
UNITED STATES STEEL CORPORATION - Pittsburgh PA
International Classification:
B05B 1/34
US Classification:
239463
Abstract:
A fuel injection lance for an ore-smelting furnace includes a central conduit, a first conduit and a second conduit. The first and second conduits are concentric with the central conduit. A central conduit is connected to a fuel mixture. The first and second conduits are in flow communication with a gas source. The first and second conduits have gas flowing at independently controllable gas flow rates relative to the other conduit. A swirl portion has a cylindrical body with a hollow interior cylinder, and vertical and helical channels formed within the body portion. Vertical channels traverse the body portion vertically to the outer surface adjacent to the bottom surface. Helical channels traverse the outer surface in a helical pattern. Vertical channels intersect with corresponding helical channels at a predetermined angle selected to provide a desired particle distribution of a fuel injected into the furnace.

International Classification:
B22D 41/02
F27D 1/16
F27D 1/00
Abstract:
A unitary refractory ring having a sidewall surrounding and spaced from a center axis, and one or more lifting lugs distributed around the center axis. The lifting lugs extend from an inner face of the sidewall towards the center axis, and are located between lower and upper axial faces of the sidewall. Each lifting lug has a lower lug face extending radially towards the center axis from the inner face of the sidewall, and a backing structure extending upwards along an axial direction from the lower lug face towards the upper axial face of the sidewall. An assembly of refractory rings, and methods for making and assembling refractory rings are also provided.
