Abstract: Metallurgical processes and systems for gas atomization of molten slag and/or molten metals from a metallurgical furnace are integrated with off-gas handling processes and equipment, such that the off-gases are fed to the gas atomization plant for atomizing the molten slag and/or molten metal. The use of by-product off-gases for atomizing molten slag and/or molten metals provides a number of benefits, including elimination of off-gas handling and treatment equipment, centralization and upgrading of heat via atomization to improve heat recovery, prevention of oxidation of granular products of atomization, and reduction of CO2 emissions. A process for preparing a granular product comprises: feeding a molten material and a by-product off-gas to a dispersion apparatus; and contacting the gas with the molten material in the dispersion apparatus, whereby the molten material is dispersed and solidified by contact with the gas to form the granular product.

Abstract: A burner is provided for a pulverous feed material. The burner has a structure that integrates the burner with a reaction vessel, and has an opening that communicates with the interior of the reaction vessel. The burner also has a gas supply channel to supply reaction gas through the opening into the reaction vessel, and a feed supply for delivering pulverous material to the reaction vessel. The burner also has a fluidic control system having at least one port capable of directing a stream of fluid at an angle to the direction of flow of the reaction gas so as to modify the flow of the reaction gas. In addition, components are provided to modify the swirl intensity and turbulence intensity of the reaction gas independently of the exit velocity.

Abstract: A method is disclosed for controlling retention time in a reactor, such as an autoclave, having a plurality of compartments separated by dividers with underflow openings. A retention time of the reaction mixture is calculated and compared with an optimal retention time, and the volumes of the reaction mixture in the compartments are adjusted while maintaining the flow rate of the reaction mixture, so as to change the retention time to a value which is closer to the optimal retention time. The reactor may include a level sensor in the last compartment for generating volume data; a control valve for controlling the liquid level in the last compartment; and a controller which receives volume data from the level sensor and controls operation of the control valve.

Abstract: A chute receives contaminant gas-laden dust from a dust collector. At least one gas injector provides an upward flow of purge gas in the chute to release contaminant gas entrained with the dust. Downstream areas are maintained at positive pressure relative to upstream areas. A purge hopper arranged below the chute collects the dust. Dust handling apparatuses allow the upward flow of the purge and contaminant gases. Movable flaps in the dust handling apparatuses include perforations that may be capped to vary the gas flow rate. A dust discharge apparatus discharges washed dust from the purge hopper.

Abstract: A gate, leaf, and method for controlling water levels in a body of water. The gate comprises a moveable barrier (which may be a leaf), a restoring device such as a spring, and a profile. The barrier automatically opens or closes an amount to allow less or more water through as a result of changes in the water pressure in the upstream body of water. This helps maintain a water level in the upstream body of water. The profile disturbs the flow of water through the gate to influence the water pressure on the barrier. The profile may help provide a more linear curve for the water moment on the barrier across the range of barrier positions. A more linear curve for the water moment may help maintain equilibrium with the restoring moment across the range of barrier positions. The method comprises disturbing the flow of water over a barrier to redistribute the pressures of the water on the barrier.
