摘要： A blast furnace with a blowpipe (12) opening through the furnace wall (11), has apparatus for analysis (20) in a raceway (18) adjacent the blowpipe opening in a bed of the blast furnace. The apparatus includes means (24) arranged in relation to the blast furnace to transmit an optical signal into the raceway, and means (30) for monitoring a received signal derived from reflection or scattering of the transmitted optical signal in the raceway. Means (32) is provided to analyse the received signal in relation to the transmitted signal and to thereby obtain a measure of a parameter of the raceway. The method of analysis comprises transmitting an optical signal into the raceway, monitoring a received signal derived from reflection or scattering of the transmitted optical signal in the raceway, and analyzing the received signal in relation to the transmitted signal to obtain a measure of a parameter of the raceway.

摘要： A method of locating an object in an optically dense atmosphere (15) includes transmitting a pulsed wave optical signal (16) towards the object through the atmosphere adjacent the object. A particular application is the location of the surface (14) of the contents of furnace (10), for example the burden (12) in a blast furnace. A received signal including at least a portion of the signal reflected by the object is monitored and analyzed in relation to the transmitted signal to determine the location of the object. This analysis comprises identifying the trailing edge of the received pulse signal to ascertain the time elapsed between the detection of the transmitted and received signals.

摘要： Apparatus for determining, in a furnace (10) having a pipe (14) along which a hot gas is transmitted to a point of introduction (15) into the furnace, the distance between the point of introduction and the surface (19, 19a) spaced therefrom, includes means (22, 24, 26) including a protective jacket (24) for transmitting a light signal along the pipe (14) within the jacket and thence from the pipe towards the surface. This means is further adapted to receive a light signal at the pipe which includes a reflection of the transmitted signal from the surface and to direct the received signal back along the pipe within the jacket (24). Means (30, 34, 36) is provided to determine the distance between the point of introduction of the gas and the surface by analysing the received signal relative to the transmitted signal. A preferred apparatus uses a laser (32), an optical fibre (22) and time-of-flight ranging.
