Patent CA-2405966-A1 (CA)
Inventor: DRY RODNEY JAMES
IPC: C21B11/00
Filed: 2001-04-11
Abstract: A molten-bath based direct smelting process and apparatus for producing metals from a ferrous material is disclosed.  The process includes injecting feed materials being solid material and carner gas into a molten bath at a velocity of at least 40m/s through at least one downwardly extending solids injection lance having a delivery tube of internal diameter of 40-200mm that is located so that a central axis of an outlet end of the lance is at an angle of 20 to 90 degrees to a honzontal axis. The feed materials injection generates a superficial gas flow of at least 0.04 Nm3/s/m2 within the molten bath at least in part by reactions of injected material in the bath. The gas flow causes molten material to be projected upwardly as splashes, droplets and streams and form an expanded molten bath zone, with the gas flow and the upwardly projected molten material causing substantial movement of material within the molten bath and strong mixing of the molten bath. The feed materials are selected so that, in an overall sense, the reactions of the feed materials in the molten bath are endothermic. The process also includes injecting an oxygen-containing gas into an upper region of the vessel via at least one oxygen gas injection lance and post-combusting combustible gases released from the molten bath.

Filed: 2003-01-09
Abstract: An exhaust gas recirculation system for a compression ignition engine is provided wherein the exhaust gas recirculation is shut off depending upon the sensed or calculated humidity in the intake manifold relative to the dew point of the exhaust/intake air mixture. The humidity of the exhaust/intake air mixture may be measured in the intake manifold, charge air mixer or the ambient humidity may be sensed. If humidity is measured in the air charge mixer or in the ambient air, other factors such as engine speed and load, intake manifold pressure, EGR flow and air/fuel ratio may be used to calculate the humidity in the intake manifold.  When the temperature of the mixture in the intake manifold is less than the dew point of the mixture, the engine control strategy may be shut off the EGR to prevent condensation in the exhaust gas recirculation system or engine.
