  • Publication number: 20250157264
    Abstract: Various systems and methods are presented regarding synchronizing data transmission between various remote clients and respective local devices. By synchronizing data transmission from the remote clients with data receipt at respective local devices, operation of the local devices can be constrained to specific periods of time. A local device can be woken from a low power mode for a short period of time, cache data, and return to low power mode. By limiting the duration of operation for the local device to receive the data, the local device can quickly return to a low power mode upon data receipt. By synchronizing data transmission from the remote clients to the local device, the duration that the local device has to be awake can be reduced. With transmission synchronization, the local device can be placed into low power mode for longer periods compared to extended operation required receive randomly transmitted data.

  • Publication number: 20250052497
    Abstract: An arrangement for heating a process gas of an iron ore pelletizing plant, including a heating chamber including a gas inlet, a gas outlet, a wall extending from the gas inlet to the gas outlet, and a heating chamber port arranged in the wall at a point intermediate to the process gas inlet and the process gas outlet, a burner assembly connectible to a source of gaseous fuel and a source of oxidant gas, and a precombustion chamber. The precombustion chamber includes a burner port and a wall extending from the burner port to the heating chamber port. The burner assembly is arranged in the burner port of the precombustion chamber and, in operation, the burner assembly introduces the gaseous fuel, the oxidant gas and/or combustion products thereof into the precombustion chamber. The burner assembly includes a fuel lance, wherein a nozzle of the fuel lance includes outlet holes, and wherein at least one of the outlet holes is arranged at an angle relative to a longitudinal axis of the fuel lance.

  • Patent number: 9719152
    Abstract: A method includes the introduction of a first medium into the compartment through an inlet and the heating of the first medium when it is present in the inlet. The heating takes place through the use of a combustion arrangement that is arranged in the inlet and that comprises fuel. The heating, the use of the combustion arrangement, includes in turn the ignition of the fuel, combustion of the fuel, and the transfer of the combustion heat to the first medium that is present at the combustion arrangement in the inlet. The combustion arrangement, is arranged in a region in the inlet, which in turn is arranged outside of the direct passage of the first medium in and through the inlet, such that the ignition of the fuel, the combustion of the fuel and the transfer of combustion heat to the first medium take place in this region.

  • Patent number: 9023127
    Abstract: A method during the oxidation and sintering of pellets includes the introduction of a first medium into the compartment through an inlet connected to the compartment and the heating of the first medium in the inlet through the use of a combustion arrangement. The use of the combustion arrangement includes the ignition of the fuel, combustion of the fuel, and the transfer of the combustion heat to the first medium that is present at the combustion arrangement. A second medium is introduced to the inlet through an intake in the direct vicinity of the combustion arrangement, where the ignition of the fuel and the combustion of the fuel take place for the transfer of combustion heat also to the second medium. The heated first medium and the heated second medium are mixed before or during their introduction into the compartment.

  • Patent number: 9011571
    Abstract: A method for the oxidation and sintering of pellets includes the introduction of a first medium into a compartment through an inlet connected to the compartment and the heating of the medium in the inlet through the use of a combustion arrangement. The use of the combustion arrangement includes the ignition of the fuel, the combustion of the fuel, and the transfer of combustion heat to the first medium that is present at the combustion arrangement. In a region in the inlet outside the direct passage of the first medium, the ignition of the fuel, the combustion of the fuel and the transfer of combustion heat to the first medium take place. By the introduction of a second medium into the region in the direct vicinity of the combustion arrangement, the combustion of the fuel and the transfer of combustion heat also to the second medium take place.
