    摘要： The invention is based on a burner device for a monitoring of a flame within a burning chamber (12a; 12b; 12c; 12d; 12e), comprising a viewing window (14a; 14b; 14c; 14d; 14e) that is arranged at the burning chamber (12a; 12b; 12c; 12d; 12e) to enable a line of sight (16a; 16b; 16c; 16d; 16e) from an outside of the burning chamber (12a; 12b; 12c; 12d; 12e) onto at least a portion of a flame-generating region of the burning chamber(12a; 12b; 12c; 12d; 12e).
    It is proposed that the burner device comprises an environment adjustment unit (18a; 18b; 18c; 18d; 18e), which is arranged on an outer side of the viewing window (14a; 14b; 14c; 14d; 14e) and is configured to control an impact of at least one environmental condition onto the outer side of the viewing window (14a; 14b; 14c; 14d; 14e).

    摘要： Disclosed is a blast furnace apparatus includes: a rotating chute; a profile measurement device configured to measure surface profiles of a burden charged into the furnace; and a tilt angle controller configured to control a tilt angle of the chute, in which the device includes a radio wave distance meter installed on the furnace top and configured to measure the distance to the surface of the burden, derives the profiles on a basis of distance data for the entire furnace obtained by scanning a detection wave of the distance meter in the furnace in a circumferential direction, and includes at least one of arithmetic units configured to command during rotation, on a basis of the surface profiles obtained, the controller to change the tilt angle of the chute, or a controller to change a rotational speed of the chute or a feed speed of the burden fed to the chute.

    摘要： The invention relates to a blast furnace (1) having a shaft-shaped furnace wall (2), which surrounds a process chamber (3), in which iron ore (4) is smelted in order to form iron (5). The furnace wall (2) has openings (8) on the periphery of the furnace wall, via which openings a hot-air blast (9) is supplied to the process chamber (3). The furnace wall (2) is surrounded by a ring line (10), in which the hot-air blast (9) is guided. Tapping lines (11) proceed from the ring line (10) and end at the openings (8) of the furnace wall (2). The tapping lines (11) consist of steel pipe (12), which is lined with a fireproof material (13) on the inside. Injection lances (16) end in the region of the openings (8), by means of which injection lances coal dust (17) is added to the hot-air blast (9), which coal dust burns inside the process chamber (3). Sensor devices (18) associated with the tapping lines (11) have sensing devices (19), by means of which the burning of the coal dust (17) is monitored. The sensor devices also have transmission devices (20), which are connected to the sensing devices (19) in respect of data transfer and by means of which data concerning the monitored burning can be wirelessly transmitted. The sensor devices (18) also have thermoelectric converters (21), which are thermally coupled to the tapping lines (11) and which produce electrical energy from the temperature difference between the tapping lines (11) and the environment of the blast furnace (1), by means of which electrical energy the sensor devices (18) are supplied with electrical energy. The steel pipes (12) of the tapping lines (11) have cut-outs (26) in partial regions. The thermoelectric converters (21) are arranged there.
