In this manual, so-called " being thermal decomposited substantially fully " or " being aerified substantially fully " mean, preferably 90 weight % of object above, more preferably 95 weight % above, be thermal decomposited more than the preferred especially 98 weight % or aerified.
The coke-oven gas that comes out from coke oven keeps 700~800 ℃ temperature usually, is blown into above-mentioned oxygen or air in the mixing zone in coke-oven gas and mixes, and the reaction that aerifies is taking place more than 950 ℃.Perhaps in mixing above-mentioned more than 1000 ℃ or spreading area that the mixing of combustion gases district is later, utilize high-temperature steam that burning generates or the high-temperature steam that is blown into, the hydro carbons that efficient will be referred to methane and even tar well carries out the water vapour modification.Importantly, from the generating unit divided combustion or carry out the blended mixing zone of the high-temperature vapor more than 1000 ℃, the outlet to the spreading area that diffusion reaction takes place keeps 5~10 degree, is more preferably 6.5~8.5 degree, the expansions of about especially 7.5 degree.
In order to confirm the present invention, make the cold mould of transparent polyvinyl chloride system of about 1/125th sizes of practical scale size.Its shape shown in Figure 1.The leftmost mould of figure forms the shape that is installed in the entrance and exit on the cylinder.In 5 moulds, heaving of below is the mixing zone on the right, and heaving of top is the spreading area.Sectional area two interregional gas flow direction is dwindling, so gaseous mixture just enters the spreading area and further accept mixing from the mixing zone, and each gas is mixed mutually in the spreading area.The diffusion angle of spreading area is followed successively by 0 degree, 2.5 degree, 5 degree, 7.5 degree, 10 degree, 12.5 degree from the mould of Fig. 1 from a left side.Visual for the diffusion-condition that makes gas, replace coke-oven gas to use cryogenic carbon dioxide, replace being blown into oxygen and steam and use the air that contains steam fog.In order to carry out the flowing qualitatively of gas in the modification device. blended is visual, utilize the light of the wavelength 488nm (blue-greenish colour) that cylinder-prism will take place from continuous oscillation Argon ion laser (Spectra-Physics:Model 177G0-2) in visibleization zone to become the slit light of the about 2~3mm of thickness, it is used as light source.High-speed camera (Photron:FASTCAM-Net 500) is used in photography, carries out in 1/500 second with the shutter speed of 500 card/seconds of picture rate.Under this condition, the pixel count of record becomes 512 * 240, and the serial photograph between about 2.1 seconds is possible.Use this device that the flow condition of cold mould inside is carried out video photography, by the picture processing of utilizing PIV (Particle ImageVelocimetry, particle image velocimeter), the instantaneous distribution of the velocity vector that inside stream is interior is quantification clearly.Then the flow velocity in the spreading area is carried out color and discern video picture.Fig. 2 converts color identification to white black, as candy strip can recognition speed difference.In expression separately, left end is corresponding to the central shaft of the container of mould, and right-hand member is corresponding to wall of a container.
The angle of loosing as can be known is 0 when spending, and the turbulent flow that takes place in the mixing zone does not disappear, and until the spreading area outlet, the flow velocity of wall just has some slow, and the position and the central part that leave wall are essentially identical flowing.That is to say that turbulent flow does not disappear.If the diffusion angle of spreading area 2.5 degree, 5 degree, 7.5 degree, 10 degree, 12.5 degree, candy strip just occurs.In Fig. 2, obtained the height (absolute value) (with reference to the right side of Fig. 3) of the cat head direction of container center portion between the banded regions of identical flow velocity (same concentrations) and wall portion.
