CONSTITUTION:A part of dehumidified coke oven gas is mixed with a dehumidified converter gas in a gas mixing vessel 5 to obtain a carrier gas. The carrier gas is introduced through a line 15 into a heat-exchanger 7 composed of radiant tubes 6 and transferred through a straightening vane 11 to a reaction furnace covered with a heat-insulation material to keep the reaction zone to 600-1300 deg.C.

摘要： PURPOSE:To also reduce the number of batteries mounted on a pig, by outputting a signal for operating a main power source closing relay during a time when signals passing through two routes are applied to an AND circuit. CONSTITUTION:When an inspection pig 4 passes below the magnets 2, 3 arranged to a pipeline 1 at the predetermined positions thereof at a speed (v), the signal passing through an amplifier 71 of a magnetic detection sensor 6 becomes an almost sine wave like detection signal having a positive peak directly under the N-pole of the magnet 2 and a negative peak directly under the S-pole of the magnet 3. When this signal is inputted to positive and negative voltage comparing circuits 72, 73 preset to a threshold value larger than a noise level in an absolute value, the outputs of the circuits 72, 73 are turned ON when exceed the threshold value. Monostable multivibrators 74, 75 are operated at the rising of the circuits 72, 73 and the outputs thereof are inputted to an AND circuit 76 and the output of the circuit 76 is turned ON only when both outputs of the multivibrators 74, 75 are turned ON and a main power source closing relay 70 is turned ON and a main power source is closed to have the discrimination capacity of a magnetic detection signal.

摘要： PURPOSE:To enable a cutting position for a repair to be accurately determined by correctly transmitting a ground reference position to an inspection pig and the like moving in a pipeline and storing the correct position of a pitting corrosion in the pig. CONSTITUTION:When an inspection pig moves in a pipeline, a magnetic sensor 40 in the pig detects the magnetism of a magnetic marker on the outer surface of a pipe. While the output of the sensor 40 is amplified (51) and transmitted to an LPF52 and an HPF53, a magnetic mark detection waveform is obtained from which noises are removed by an interaction between the output of an F/V converter that generates a voltage proportional to the moving speed of the pig and filters 52 and 53. An output thus obtained is inputted to a gate circuit 55 controlled by the data set to a voltage comparing circuit 54 and the output of the circuit 55 is inputted to a cross detector 56 to generate a pulse indicative of passing a reference position. Thus, the correct position of a pitting is stored and a correct cutting position for a repair can be determined.
