摘要： A method for controlling a fuel supply to a plurality of burners of a burner group includes determining a temperature in the burner group as a control variable. The fuel supply to the burners of the burner group is specified in dependence on a control deviation of the temperature determined in the burner group to a specified setpoint temperature. The fuel supply is a common mean fuel supply that is specified for all of the burners of the burner group by a temperature master controller. The fuel supply is corrected for each of the burners or burner subgroups of the burner group. Each of the burners or the burner subgroups have a fuel supply slave controller. The fuel supply slave controllers use at least, one disturbance variable associated to the respective burner or the respective burner subgroup so as to perform the correcting.

摘要： The object of this invention is to provide an ash-melting furnace which can respond to fluctuations in the load and which will be capable of highly efficient and stable operation. In an ash-melting furnace which heats and melts the primary ash and the fly ash obtained by combustion together, this invention is characterized by supplying the primary ash (ash containing rough particles) from upper end of the furnace to form an upper layer of a two-tiered layer of ash, supplying the fly ash (ash containing minute particles) from an upper end of the furnace to form a lower layer of the two-tiered layer of ash, moving the two-tiered layer together towards the far end of the furnace, and heating and melting the two-tiered layer by a burner to form molten slugs during the moving step. When the burner is an oxygen-enriched burner, this configuration makes it possible to control the volume of oxygen to be added to the burner air (including changing the density of the oxygen). This invention can control not only the volume of fuel but also the density of the oxygen-enriched air and the volume of the ash to be supplied in response to the state of flow of the molten ash melted by the oxygen-enriched burner.

摘要： Significant energy savings are achieved in the operation of reheat furnaces when the preheat zone temperatures are maintained as low as possible consistent with the demands of the hot strip mill. While the benefits of this invention may be realized through manual adjustment, further energy savings are achieved through the utilization of automatic controls and proper scheduling in which slabs of approximately the same thickness are placed into groupings so that a first grouping of tandum slabs enters the furnace, followed by a second grouping of different thickness.

摘要： The invention relates to a method for operating a furnace, wherein a starting material comprising at least one metal element is molten, wherein the starting material is heated by at least one burner that is operated with a fuel volume flow of a fuel and an oxidant volume flow of an oxidant. An exhaust gas temperature of the furnace is monitored in an exhaust gas line at least at one measuring point downstream of a post combustion zone, wherein in a standard operational state a target fuel volume stream and a target oxidant volume stream is fed to the burner, wherein a change of the exhaust gas temperature is recorded at predetermined time frequencies and is compared to a predetermined threshold value. The invention is characterized in that when the change of the exhaust gas temperature per time unit is greater than the threshold value, the burner is put into a reduced operational state for a predetermined time, wherein the quotient of fuel volume stream to oxidant volume stream is lowered by at least one of the following actions: A) a predetermined sudden reduction of the fuel volume stream to a reduced volume stream and B) a predetermined sudden increase of the oxidant volume stream to an increased volume stream, said quotient being reset to the standard operating state after the reduction period.

摘要： Calcination of petroleum coke in a rotary kiln is monitored by optical pyrometer inspection, inward from the coke discharge end, at a plurality of places spaced longitudinally inside the kiln, with the improved result of enabling the kiln to be controlled so that desired readings at one of the places, e.g., nearest the coke discharge end, are not impeded or falsified by flame and smoke conditions caused by burning of volatiles. Since pyrometer readings are found to produce a special signal due to flame or smoke, the use of the plural inspections permits detecting the location of such conditions and controlling the kiln to keep the flame and smoke from reaching the place of desired readings.
摘要翻译：在回转窑中煅烧石油焦是通过光学高温计检查，从焦炭排出端向内，在窑内纵向间隔开的多个位置进行监测，其结果是能够控制窑以使得所需的读数在一个的位置，例如最靠近焦炭排放端，不会被挥发物燃烧引起的火焰和烟雾条件阻碍或伪造。由于发现高温计读数由于火焰或烟雾而产生特殊信号，所以使用多次检查可以检测这种状况的位置，并控制窑将火焰和烟雾保持在所需读数的位置。
