摘要： PCT No. PCT/DE96/01442 Sec. 371 Date Apr. 21, 1998 Sec. 102(e) Date Apr. 21, 1998 PCT Filed Jul. 24, 1996 PCT Pub. No. WO97/05439 PCT Pub. Date Feb. 13, 1997A process for feeding bulk material onto a belt of a rotary hearth furnace, which has hoods that cover the hearth belt in such a manner as to form a ring. The bulk material is deposited on a transport device at a layer thickness proportionately dependent on the distance to the rotary hearth center. The transport speed of the transport device is set at a certain value; the surface of the bulk material is smoothed; and then the bulk material is distributed at a constant layer height over the entire width of the hearth belt.

摘要： PROBLEM TO BE SOLVED: To remove the carbon deposited around the charging hole of a coke oven, without damaging the oven wall, with high efficiency and a shot time, and with a simple device. SOLUTION: After the inclination of four air-feeding lance 15 to the vertical direction is reduced, this device is inserted into charging hole 5. Then, the inclination of air-feeding lance 15 to the vertical direction is expanded. A plurality of air-spraying nozzles 37 which are disposed in the longitudinal direction of each air-feeding lance are held at roughly the same distance from the inclined surface of charging hole 15 and are also directed to four corner portions which are likely to have much deposited carbon. Air is now sprayed from air-spraying nozzles 37, to remove deposited carbon efficiently by burning and/or lift-off.

摘要： PROBLEM TO BE SOLVED: To prevent the increase in carbon removal cost necessary in using high-volatile-content coal without damaging the wall of a coke oven and to greatly contribute to solving the problem of exhaustion of caking coal due to the widening of the limit of coal allowed to use by setting the position for charging high-volatile-content coal into a coke oven chamber near at the wall of the coke oven. SOLUTION: High-volatile-content coal cut out from a hopper is charged to a position near the wall of a coke oven chamber of a chamber oven. A charging car used has a charging shoot which is divided in the direction of the oven width by partition boards 1, 2 into the central charging port C an wall-side charging ports S1 and S2 . Medium- to low-volatile-content coal is charged through the central charging port C, and high-volatile-content coal is charged through the wall-side charging ports S1 and S2 . Thus, high-volatile- content coal can be compounded in a large amt. while avoiding the lowering in productivity due to carbon adhesion troubles or the problems with the acceleration of oven damage.

摘要： PROBLEM TO BE SOLVED: To realize a high density plug type conveying in pneumatic conveying and charging of coal to coke-oven. SOLUTION: Using high density plug type pneumatic conveying as a pneumatic conveying, the open-to-shut ratio of plug forming valves 16, 17 and a carrier gas supplying state to the coal hopper 15 are controlled. A deaerator 14 having a cirumferential slit is installed on the transport pipe 13 near the coal charging port 12 and the carrier gas separated by the deaerator 14 is introduced to the particle collecting device 20 connected through coal charging port 12 and charging valve 21 to separate the coal. Thus the amount of introduction of the carrier gas into the coke-oven is reduced.

CONSTITUTION: The drawing is a side view of an apparatus for removing carbon deposited on the charging port of a coke oven. This apparatus comprises a particulate ejection nozzle mechanism A and a blast generating mechanism B. A coke oven 1 comprises an oven wall 1A, a charging port 1B, and a coke oven chamber 1C. The mechanism A has a particulate ejection nozzle 2 which can be inserted into the charging port 1B. A nozzle 2 is held on a body base 10 by means of a holder 3, and the inclination angle is variable by means of an inclination cylinder 4. The mechanism B comprises a hopper for storing and taking off particulates and a compressor for application of a high pressure gas. A mixed material comprising a coke powder and a blast material is suitable as the hard particulates.
