Relatively high speed methods for increasing the bulk density of coal particles, apparatus for increasing the bulk density of coal particles and methods for making metallurgical coke. Once such method includes depositing coal particles onto a charging plate external to a coking oven to provide an elongate bed of dry, uncompacted coal having an upper surface of the charging plate. The charging plate has side walls, and at least one movable end wall An impact pressure is applied to the upper surface of the bed of dry, uncompacted coal while degassing the coal to provide a dry, compacted coal bed having a bulk density ranging from about 960 to about 1200 kilograms per cubic meter.

Method and apparatus for compacting coal for a coal coking process

The invention provides a coke oven charging machine (10) including a mobile frame (64) and a coke oven feed device (20) on the mobile frame. The coke oven feed device includes a movable, elongate charging plate (28) having a first end and a second end, retractable side-walls (48) adjacent the charging plate, first and second end walls (44 & 46) adjacent the first and second ends of the charging plate and a shuttle section adjacent the first end of the charging for spanning an area between the first end of the charging plate and an entrance to the oven. The shuttle section has opposed shuttle side walls (52) and a shuttle end wall (50). A charging plate moving device (60) is provided for moving the charging plate into and out of the oven. The charging machine apparatus provides a means for quickly charging coking ovens with a compacted coal charge so that lower quality coals may be used to make metallurgical coke.

Method and apparatus for coal coking

The present technology describes various embodiments of systems and methods for handling emissions. More specifically, some embodiments are directed to systems and methods for collecting heated particulate from a coal processing system. In one embodiment, a method of handling emissions from a coal processing system includes inletting the emissions into a duct. The emissions include heated particulate. The method further includes slowing a speed of the emissions traveling through the duct and disengaging the heated particulate from the emissions without the use of a physical barrier. In some embodiments, the heated particulate is slowed, cooled, and diverted from an emissions pathway into a collection bin.

Methods for handling coal processing emissions and associated systems and devices

A method for producing non-recovery/heat recovery coke may include the steps of providing a container, disposing a volume of loose coal into the container such that a vertical dimension of the volume of loose coal in the container is smaller than a horizontal dimension of the volume of loose coal, applying a force to the coal in the container to produce a volume of compacted coal having a substantially uniform density which is larger than that of the loose coal, disposing the compacted coal into a non-recovery/heat recovery type oven, and heating the compacted coal to produce coke. The method may also include the steps of providing a container, and moving the non-recovery/heat recovery coke mass from the oven at a substantially constant elevation to the container, quenching the coke mass in the container to produce a quenched coke mass, and removing the quenched coke mass from the container.

Method for producing blast furnace coke through coal compaction in a non-recovery or heat recovery type oven

A coke oven includes an oven chamber, an uptake duct in fluid communication with the oven chamber, the uptake duct being configured to receive exhaust gases from the oven chamber, an uptake damper in fluid communication with the uptake duct, the uptake damper being positioned at any one of multiple positions, the uptake damper configured to control an oven draft, an actuator configured to alter the position of the uptake damper between the positions in response to a position instruction, a sensor configured to detect an operating condition of the coke oven, wherein the sensor includes one of a draft sensor, a temperature sensor configured to detect an uptake duct temperature or a sole flue temperature, and an oxygen sensor, and a controller being configured to provide the position instruction to the actuator in response to the operating condition detected by the sensor.

Automatic draft control system for coke plants

The aim of the invention is to provide a method and a stamping device which is affiliated with said method. Using known economical stamping techniques, the stamping device permits coke coal cakes which are produced in an edgewise manner to be inserted into a coking furnace in a manner suited for positioning i.e. in a flat-lying manner. To this end, a coke coal cake (1) having a small cake height and a large cake base surface is stamped inside a stamp die in an edgewise arrangement while using known techniques. Afterwards, the coke coal cake (1) remains in the stamp die and is placed in a position by a tipping and holding device (3) which is placed on the stamp die and which is suited for carrying out functions. In said position, the coke coal cake (1) which has not yet been removed from the die is inserted into the furnace chamber, is removed from the die therein, and is placed on the furnace base. This is especially achieved by using an inventive stamping device which is characterized in that a tipping and holding device (3) is connected to the stamp die of a stamping machine. A setting base (2) is arranged in the tipping and holding device such that the base is both a part of the stamp die and a part of the setting base.
