摘要:
The present invention discloses a blast-furnace operation method which comprises selecting three factors, i.e. the oxygen volume in blast, the ore/coke and the reducibility of the burden materials as control factors from among these which participate in the variation of heat input and heat output of blast furnace, plotting values of these three factors obtained from the practical operation of efficient blast furnaces on a graph consisting of three parallel axes indicating the three factors, evaluating the conditions of furnace heat with reference to a balanced state of the three plotted factors and adjusting one or more of the three factors in the furnace so all will lie within a suitable range thereby balancing the furnace heat.

An electric power control device can have multiple fuel cells, loading devices driven by the electric power supplied by the multiple fuel cells, and a control device for operating the fuel cells in response to the electric power load required by the loading devices. The control device can have an efficiency characteristics recognition device for recognizing the efficiency characteristics for each of the multiple fuel cells, an electric power requirement recognition device for recognizing the electric power required by the loading devices, and a fuel cell operation control device for controlling the operation of the fuel cells so that the efficiency characteristics get closer to the maximum efficiency loading point in response to the recognized electric power requirement.
摘要:
A reformed gas composed mainly of hydrogen and carbon monoxide to be used for a fuel cell is produced by using a multi-tubular reformer provided with bayonet type double-wall catalyst tubes and feeding hydrocarbon gas such as natural gas and steam to the reformer. Porous media of a ceramic material are arranged in such a manner in a shell side flue gas inlet part of the interior of the reformer as to envelop the leading end parts of the catalyst tubes. The transfer of heat from the flue gas to the catalyst tubes is enhanced because the porous media accumulate the heat from the flue gas and radiate the accumulated heat in the direction of the walls of the outer tubes of the catalyst tubes. The otherwise possible uneven transfer of heat to the catalyst tubes is prevented because the wall effect and the channelling of the flue gas are repressed. This invention, therefore, permits effective utilization of the thermal energy of the flue gas for the reforming reaction and enables the reformer to be stably operated.
