Abstract: A screening apparatus comprises superposed screening decks with an upper one of the screening decks having a pellet input, and each screening deck ends with an oversize pellet output, the screening decks have screens to screen the green ore pellets from top to bottom, the oversize pellet outputs feeding the travelling grate through pellet chutes with the oversize green ore pellets of one of the upper and the lower one of the screening decks being superposed to oversize green ore pellets of the other one of the lower and the upper one of the screening decks, the pellet chutes defining a curved delivery path with an input slope at the chute pellet input greater than an output slope of the chute pellet output to reduce a delivery speed of the green ore pellets from the oversize pellet output to the travelling grate. There is also provided a method for screening and delivering green ore pellets onto a travelling grate of an induration furnace.

Abstract: A method of operating a burner assembly is provided. The method generally includes transporting combustible fuel and atomization air through concentric fluid lines of the burner assembly; mixing the combustible fuel and the atomization air to atomize the combustible fuel; adjusting a flow of the combustible fuel and the atomization air to obtain atomized fuel with an air-to-fuel atomization ratio of less than 0.6; outputting the atomized fuel from a nozzle of the burner assembly; and igniting the atomized fuel to produce a flame. A burner assembly operable by the method, and a corresponding nozzle are also provided.
