摘要:
This invention provides processes and systems for converting biomass into high-carbon biogenic reagents that are suitable for a variety of commercial applications. Some embodiments employ pyrolysis in the presence of an inert gas to generate hot pyrolyzed solids, condensable vapors, and non-condensable gases, followed by separation of vapors and gases, and cooling of the hot pyrolyzed solids in the presence of the inert gas. Additives may be introduced during processing or combined with the reagent, or both. The biogenic reagent may include at least 70 wt%, 80 wt%, 90 wt%, 95 wt%, or more total carbon on a dry basis. The biogenic reagent may have an energy content of at least 12,000 Btu/lb, 13,000 Btu/lb, 14,000 Btu/lb, or 14,500 Btu/lb on a dry basis. The biogenic reagent may be formed into fine powders, or structural objects. The structural objects may have a structure and/or strength that derive from the feedstock, heat rate, and additives.

The invention relates to a device on a coal charging car for lifting covers from filling hole frames in the furnace roof of a coke furnace and for cleaning the filling hole frames. The basic design of the device comprises a cover lifter (3) having a supporting arm (4) with a lifting magnet (5), a frame cleaner (6) having a supporting arm (4') with a cleaning head (7), and lifting devices (8, 8') for vertically adjusting the supporting arms (4, 4'). The cover lifter (3) and the frame cleaner (6) can be horizontally displaced by means of a travelling gear (12, 12') between an operating position (A) in which the lifting magnet (5) or the cleaning head (7) is aligned with a filling hole (13) in the furnace roof of the coke furnace, and a rest position (B) spaced apart from the filling hole. The device according to the invention is characterized in that the travelling gear (12, 12') comprises a travelling frame (15) which can be horizontally displaced on tracks (14) on the underside of the coal charging car along a first axis and a supporting frame (16) arranged inside the travelling frame (15), said supporting frame (16) being movably guided on the travelling frame along a second axis at a right angle to the direction of movement of the travelling frame (15), and the lifting devices (8, 8') for the cover lifter (3) and/or the frame cleaner (6) being arranged on the supporting frame.

A coke furnace is coated with a coating film which has a high strength, high impact resistance, excellent smoothness, and high durability and is capable of protecting the refractory bricks of the coke furnace over long. A coating material which comprises as main ingredient 18 to 70 % by weight SiO2, and 10 to 60 % by weight Na2O and/or K2O and contains at least one member selected among 2 to 14 % by weight P2O5, 0.5 to 25 % by weight BaO, 0.5 to 25 % by weight SrO, and 0.5 to 20 % by weight Fe2O3 is sprayed over refractory bricks to remove the carbon adherent to the bricks and form an exellent coating layer.

The utility model relates to a feed charging and discharging apparatus of coke oven, especially relates to a dust removing coke guide vehicle used in horizontal carbonization chamber. The coke guide vehicle includes steel framework, running mechanism, coke guide device, door cleaning device and two-ends coke disposal apparatus, characterized in that a door lifting and door jamb cleaning apparatus is mounted on the steel framework. The said door lifting and door jamb cleaning apparatus comprise coke oven door lifting device and coke oven door jamb cleaning device and rotation device, wherein the door lifting device and the door jamb cleaning device are arranged on said framework at an angle of 90°. On the steel framework above the coke guide device and near the coke oven side there is a moving framework of smoke collection on cokery mouth. Adding a moving framework of smoke collection on cokery mouth can realize simultaneous collection of smoke from coke at cokery mouth and coke separated from the oven, which can obtain a good dust removing effect. Integrating the door lifting device and the door jamb cleaning device together provides compact structure for the coke guide vehicle. It helps to finish the operation of the carbonization chamber with one hole at two positions, and saves operation time. Two-ends coke disposal apparatus can automatically dispose the end coke generated from coke guide, door cleaning and door jamb cleaning, which can reduce the manpower.

Die Erfindung betrifft ein Verfahren zur Reinigung von Koksofenkammertüren einer Koksofenbatterie oder einer Koksofenbank, durch das das zeitaufwendige Reinigen von Koksofenkammertüren in der zeitlichen Dauer erheblich verkürzt wird, indem in einem Ofentürschlitten mindestens eine gereinigte Koksofenkammertür bereitgehalten wird, so dass eine zu reinigende Koksofenkammertür unmittelbar nach der Herausnahme aus der Koksofenkammer gegen eine gereinigte Koksofenkammertür ausgetauscht werden kann. Das Verfahren umfasst dabei die Überführung einer Koksofenkammertür in eine Reinigungsposition des Ofentürschlittens, so dass diese gereinigt werden kann, und eine unmittelbar darauffolgende Entnahme einer gereinigten Koksofenkammertür aus einer Lagerposition des Ofentürschlittens, so dass diese direkt in die Öffnung der Koksofenkammer eingesetzt werden kann, und eine Reinigung und Überführung der zu reinigenden Koksofenkammertür in die Lagerposition. Die Erfindung betrifft auch eine Vorrichtung zur Ausführung dieses Verfahrens, welche aus einem Ofentürschlitten besteht, der mit einer Lagerposition und einer Reinigungsposition ausgestattet ist.
