Abstract:
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.
Abstract:
A charcoal making kiln has a combustion chamber having a pyrolysis chamber enclosed therein for pyrolytic conversion of pyrolysis feed material above combustion material burning atop a fire bed of the combustion chamber in use. The pyrolysis chamber has a substantially airtight hatch accessible via a front of the combustion chamber. The pyrolysis is chamber located within an upper region of the combustion chamber such that substantially an entire exterior surface of the pyrolysis chamber is exposed within the combustion chamber for heating.
