A composite placement machine has a simplified fiber delivery path from a creel to a lay-up table. A carriage is mounted for motion in the Y-axis along the length of an overhead beam. A composite placement head having a shiftable compaction roller is supported by the carriage. A stationary creel at one end of the overhead beam forms a band of composite material having a width that extends in the X-axis. A lay-up table is mounted for motion in the X-axis and rotary motion about a C-axis that is perpendicular to the X and Y-axes. The motion of the head in the Y- axis, the shiftable compaction roller, and the motion of the lay-up table X-axis and the C-axis allows the head to apply composite material to the lay-up table in both Y-axis directions in any orientation without twisting the band of composite material relative to the X and Y-axes.

A method directs fuel-oxidant premix into a reaction zone through a first total premix inlet flow area, and causes the premix to combust and form a stable flame projecting into a process chamber through an outlet from the reaction zone. At a time when the process chamber has a temperature at or above an auto-ignition temperature of the fuel, the flame is blown off to initiate diffuse combustion in the process chamber without a stable flame. The flame is blown off by directing the premix into the reaction zone through a second total premix inlet flow area greater than the first total premix inlet flow area.

Method and burner for reducing nitrogen oxide emissions during the combustion of a gaseous fuel
A method for reducing nitrogen oxide NOx emissions during combustion of a gaseous fuel in a burner intended for a naked-flame or controlled-atmosphere reheating furnace, for reheating steel products or for continuous coating and/or annealing of metal strips, wherein a first dilution is carried out by mixing combustion air with combustion products upstream from or in the body of the burner, and a second dilution is carried out directly at the level at which the gaseous fuel reacts with the combustion air, mixing the fuel with a recirculated portion of the flame or products of partial combustion, the double dilution enabling the physical and chemical properties of the gas to be modified in order for the burner to operate with low oxygen rates and obtain a flame that produces a very low level of NOx production regardless of the temperature of the enclosure in which the combustion takes place.
F23C 9/08 - Combustion apparatus characterised by arrangements for returning combustion products or flue gases to the combustion chamber for reducing temperature in combustion chamber, e.g. for protecting walls of combustion chamber
A method supplies reactants, including fuel gas, to burners that discharge the reactants into a furnace process chamber. In a stable flame mode of operation, stable flames are projected from the burners into the furnace process chamber. At a time when the furnace process chamber has a temperature at or above an autoignition temperature of the fuel gas, a diffuse combustion mode is initiated by supplying a selected burner with additional reactants, including reactants diverted from another burner, to blow off the stable flame at the selected burner.
Disclosed is a method for continuous thermal treatment of a steel strip. The strip passes through consecutive thermal treatment chambers, is quickly cooled in at least one of the chambers by spraying liquid onto the strip, or by spraying a fluid made up of gas and liquid or spraying a combination of gas and liquid forming a mist. After quick cooling, a protective metal layer is deposited on the strip by dip coating. The cooling fluid strips iron oxides or other alloy elements contained in the steel to be treated, minimizing oxidation and reducing the oxides on the strip. Spray pressure and distance are chosen to facilitate the stripping property and the mechanical action of the sprayed fluid, reducing the layer of oxides on the strip. The temperature of the strip at the end of the cooling step is the temperature necessary for carrying out the desired treatment cycle.
