摘要： PROBLEM TO BE SOLVED: To effectively utilize waste plastics as inexpensive fuel and to reduce the production cost by providing a firing furnace for firing raw ores, such as lime stone and dolomite, with a waste plastic blowing lance having a specific lance diameter. SOLUTION: The firing furnace is provided with the waste plastic blowing lance 6 having a lance diameter D1 satisfying the equation. In the equation, D1 is the diameter of the waste plastic blowing lance; Fp is a waste plastic supply rate (kg/sec); t is a waste plastic firing time (sec); θ is an angle of repose of the raw ores ( deg.); Pp is a waste plastic bulk density (kg/cm ). Namely, the slope of the angle of repose (θ) on which the raw ores glide down diagonally along a direction toward the center from the peripheral edge is formed at the front end portion of the waste plastic blowing lance 6 entering in a raw ores packed bed 5 and a gap 7 is formed above this slope. The gaps among the adjacent lime particles and the spacing at the bottom of the lance in addition to this gap part also contributed to the combustion of the waste plastic. The volume twice the volume of this gap part is used as the gap part volume effective for combustion.

摘要： PURPOSE:In a dry extinguishing furnace for coke, the secondary cooling gas is blown from the undermost part of the gas-blowing funnel in the cooling chamber to extend the cooling zone, thus enabling the contraction of the volume of the cooling chamber, resulting in increase in the cooling efficiency of the dry extinguishing of coke. CONSTITUTION:In a dry extinguisher for coke, the first cooling gas inlet 12 is formed with funnels 11 and 11a beneath the furnace 10. The circulation gas is heat exchanged, sent through a ring pipe 13 and the inlet 12 into the chamber and distributed by the distributor 15 on the center, thus cooling the red-heated coke in the furnace. Then, the secondary cooling gas is blown in through another inlet 22 for the secondary cooling gas at the undermost end of the funnel 11 and/or through the third inlets 23 on the upper hopper 18 which is placed beneath the funnel 11. The cooled coke is cut out by the cutting gate 17 into the upper hopper 18 and sent out to the lower hopper 20 by opening the upper trap 19.

摘要： PURPOSE:To rationalize the work for adhering rings to a lance by mortar by providing a ring support device to a carriage for assembling the lance. CONSTITUTION:The rings 5 inserted onto a lance steel pipe 4 are assembled over the carriage 10 while the rings are held supported by ring 5 supporters 17. Such assembly is fixed onto a working floor by simultaneously hoisting the top end of the steel pipe 4 and the end brace 18 of the top end of a shaft 16 and inserting the rod into a hole 13d of guide 13b of a gripper 13a for the lance base part 4a at the bottom end in the adhering work place. Ring 5 supporting rings 17a which contact with stopper plates 17c of the supporters 17 are then rotated successively from the lower side around the shaft 16 and the rings 5 are dropped by each piece. The mortar is coated atop the rings 5 by utilizing the spacings generated between the rings 5 and 5 and the ring 5 upper than the coated ring is dropped thereonto so that the rings are adhered. The above-mentioned rod is removed when the adhesion of 4-5 pieces of the rings 5 is completed. The lance, etc. are lowered and when a guide 20 for fixing the lower lance comes to the position of the working floor, the rod is inserted into the guide 20 to fix the lance. The adhesion and assembly of all the rings 5 are completed by the same procedures mentioned above.

摘要： PURPOSE: To keep boiler function even when coke can not be cut down from lower part and to prevent the residence of gas in a furnace, by a method wherein in a cooling gas-forced circulation system the downstream side of a waste-heat boiler is connected to the top part of a furnace, and a by-pass pipe line is provided which is opened as the occasion demands.
CONSTITUTION: The downstream side of a waste-heat boiler 25 is connected to the top part of a quenching furnace 25, and a by-pass pipe line 43 is provided which is opened as the occasion demands. When the supply of cooling gas becomes impossible by a trouble, an on-off valve 45 is adjusted and an on-off valve 44 is opened. The cooling gas is passed through the by-pass pipe line 43 into a duct 42, and then into the top part 38 of the furnace. Then the gas is contacted with red hot coke which is placed within a prechamber 25A and is not quenched under normal conditions. The gas heated to a high temperature is forcedly recycled through a throughhole 30, a circular gas 29, a duct 32, a waste-heat boiler 31 and a blower 34 to the by-pass pipe line 43. In this way, the same quantity of heat as during normal operation can be supplied to the waste-heat boiler 31. Since the recycling of the gas is continued, the prechamber is prevented from being filled with combustion gas.
