A method of operating a burner assembly is provided. The method includes the steps of: providing combustible fuel at the input end of the burner assembly; providing atomization air at the input end of the burner assembly; transporting the combustible fuel and the atomization air to the output end of the burner assembly through concentric fluid lines; 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 at the output end of the burner assembly; and igniting the atomized fuel to produce a flame. A burner assembly operable by said method, and a corresponding nozzle are also provided.

A grate bar is provided for use in forming a grate bar assembly of a sintering pallet car. The grate bar comprises an elongate body having top surface for receiving a load, a pair of opposed arms, and a pair of opposed feet, with each arm and foot pair retaining the frame of the car therebetween. Each of a pair of peripheral spacers extends laterally away from the body to distance the body from a body of an adjacent grate bar. Each of a pair of central spacers is located between the peripheral spacers and extends laterally away from the body to distance the body from the body of the adjacent grate bar. At least one of the plane defined by a peripheral spacer top wall and the plane defined by a central spacer top wall is below the plane defined by the top surface of the elongate body.

Setter plates are fabricated from Li-stuffed garnet materials having the same, or substantially similar, compositions as a garnet Li-stuffed solid electrolyte. The Li-stuffed garnet setter plates, set forth herein, reduce the evaporation of Li during a sintering treatment step and/or reduce the loss of Li caused by diffusion out of the sintering electrolyte. Li-stuffed garnet setter plates, set forth herein, maintain compositional control over the solid electrolyte during sintering when, upon heating, lithium is prone to diffuse out of the solid electrolyte.
