Abstract
A tuyere stock for use in the delivery of heated gas from a source to a furnace and characterized by the provision of a rigid connection between the injection nozzle portion of the stock and the blast tuyere which injects the heated gas to the furnace interior is disclosed. The injection nozzle portion of the tuyere stock is supported by guide means which maintains the blast tuyere in its proper operating position by preventing angular movement thereof while permitting motion thereof resulting from thermal expansion. The tuyere stock is further characterized by means which urges the blast tuyere against the furnace wall with a preselected minimum force.
