| 20120103782 | REFRACTORY OVEN DOORS AND REFRACTORY OVEN DOOR FRAMING WALLS OF A COKE OVEN BATTERY - A heat-resistant door device for closing a horizontal coke oven chamber is made of a refractory material, using a material containing silica or a material containing silica and aluminum oxides, in particular. The material has a low temperature expansion coefficient and it is thermally well insulating so that the door is not deformed and/or distorted during the coal carbonization process. The door device is built of a coke oven wall mainly located above the door and embracing the door as well as of a mobile door located underneath. Thereby less cold ambient air enters into the coke oven chamber and radiation losses are minimized. The door may be comprised of an ellipsoidal bulge by, which the coke can be better pushed into the coking chamber. The oven wall embracing the oven door can also be made of a refractory material containing silica or of a material containing silica and aluminum oxides. | 05-03-2012 |
| 20130062187 | METHOD FOR COLLECTING RESIDUAL COKE FROM NON-RECOVERY AND HEAT-RECOVERY COKE OVENS - A method is disclosed for collecting so-called residual coke from a coke oven chamber while the door of the coke oven chamber is being opened. A collecting device is moved up against a guide plate arranged under the door of the coke oven chamber before the door of the coke oven chamber is opened, and the coke that falls out of the coke oven chamber falls across the guide plate into a collecting device. The collecting device is moved to a horizontal position after the coke has been collected so that the upper edge of the collecting device is at the height of the bottom of the coke oven chamber. The push-out device of the coke oven operating machine moves over the collecting device between the suspensions so that the coke is pushed out of the collecting device back into the coke oven chamber. | 03-14-2013 |
| 20140048406 | DEVICE AND METHOD FOR INCREASING THE INTERNAL SURFACE OF A COMPACT COKE CHARGE IN A RECEIVING TROUGH - A device for increasing the interior surface of a compact coke charge in a receiving trough, which device increases the interior surface of a coke cake or coke leaving the coking chamber by mechanically breaking apart or roughening it, resulting in a break-up of the coke structure and the formation of crevice-type cavities in the compacted coke charge so that an increased amount of water can flow into the interior of the coke charge during the subsequent quenching step through these crevices, resulting in a high profitability of the method due to reduced quenching times and lower water consumption. A method for increasing the interior surface of a compact coke charge in a receiving trough, which serves to break up a fresh coke cake or to roughen the coke in order to reduce water consumption during quenching is disclosed. | 02-20-2014 |
| 20140110241 | PROCESS AND APPARATUS FOR CONTINUOUS PRODUCTION OF DENSIFIED CHARCOAL - The invention relates to an apparatus and method for the production of densified charcoal from organic material that can be used for example as chemical reagents, fuels, or absorbents. The reaction vessel defines a flow path extending from the input to the vessel, through to the output from the vessel, in which the thermal decomposition of the organic material progresses as the organic material passes through the reaction vessel. The vessel includes a reaction zone for autogenous reaction of organic material in a reaction bed of the organic material. Pressure can be applied to the bed of organic material to increase the density of the resultant charcoal. Acoustic emitters may also be used to enhance the densification process. | 04-24-2014 |
| 20150107982 | APPARATUS AND METHOD FOR PYROLYZING COAL WITH WIDE PARTICLE SIZE DISTRIBUTION - A carbonization apparatus for coal with wide particle size distribution, a carbonization apparatus unit, and a carbonization method based on the apparatus. The apparatus comprises a char discharge outlet ( | 04-23-2015 |
| 20160060536 | METHOD AND SYSTEM FOR OPTIMIZING COKE PLANT OPERATION AND OUTPUT - The present technology is generally directed to methods of increasing coal processing rates for coke ovens. In various embodiments, the present technology is applied to methods of coking relatively small coal charges over relatively short time periods, resulting in an increase in coal processing rate. In some embodiments, a coal charging system includes a charging head having opposing wings that extend outwardly and forwardly from the charging head, leaving an open pathway through which coal may be directed toward side edges of the coal bed. In other embodiments, an extrusion plate is positioned on a rearward face of the charging head and oriented to engage and compress coal as the coal is charged along a length of the coking oven. In other embodiments, a false door system includes a false door that is vertically oriented to maximize an amount of coal being charged into the oven. | 03-03-2016 |
