A grate bar for mounting in arrays of adjacent grate bars in a pallet car of a sintering or pelletizing machine includes an elongate crossbeam extending in a longitudinal direction of a horizontal plane, with a middle section between two opposite end sections. The crossbeam has a generally rectangular cross-section with an upper surface for receiving bulk material thereon, an opposite lower surface, and peripheral surfaces for facing adjacent grate bars. The crossbeam has two legs to vertically secure the grate bar to the pallet car. The end sections of the crossbeam include first interlocking components shaped and arranged such that they cooperate with first interlocking components of grate bars of a neighbouring row of grate bars; thereby limiting relative translations of two neighbouring grate bars in at least a vertical and a horizontal orientation. The first interlocking means components have a triangular cross-section in a horizontal plane.

Grate bar for a pelletizing or sintering machine

A system and method for monitoring the condition of a travelling grate machine including univocally identifying each pallet car; collecting a plurality of condition indicating parameters for the wheels, the grate bars, the car body and/or the side walls of the pellet car; attributing the collected condition indicating parameters to an individual pallet car; storing the collected condition indicating parameters for each pallet car in a database; evaluating the condition of the travelling grate machine; comparing the different condition indicating parameters collected by the different sensor means of each pallet car to reference parameters and/or to previously collected condition indicating parameters of that same pallet car; identifying the faults in each pallet car based on this comparison; classifying each pallet car according to its need of maintenance based on the severity of different identified faults; and determining the pallet car in most need of maintenance based on this classification.

Travelling grate condition monitoring

A method for providing raw material for an industrial process, in particular for steel production, the method including torrefying a torrefaction material, which contains biomass, in a reactor by thermochemically treating the torrefaction material at 200° C. to 600° C., to obtain bio coal, extracting the bio coal from the reactor at a first temperature of up to 600° C., providing bulk materials at a second temperature between 0° C. and 100° C., mixing bio coal with bulk material, thereby cooling down the bio coal with the bulk material and obtaining a mixture of bulk material and bio coal at a third temperature, below the self-ignition temperature of the mixture, and using the mixture to provide the raw material for the industrial process.

Method for providing raw material for an industrial process

A method for charging pallet cars of a traveling grate for the thermal treatment of bulk material includes in a first step a first layer is applied as a hearth layer on a grate surface of the pallet car. In at least one second step a second layer at the same time or successively is applied as a side layer on two opposed side walls of the pallet car and a third layer is applied as green pellet layer between the side layers and on the hearth layer. The pellets used for the grate and the side layer differ in terms of their diameter and size distribution.
