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

A method of producing coke comprising the steps of:

• disposing a volume of coal into a non-recovery type oven having an oven floor;
• heating the volume of coal to produce a coke mass having an apparent specific gravity of about 1.05;
• providing a container;
• moving the 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, wherein the step of quenching comprises the step of recovering the heat transferred to the volume of water by the coke mass;
• and
• removing the quenched coke mass from the container.

• quenching the coke mass in the container to produce a quenched coke mass, wherein the step of quenching comprises the step of applying liquid nitrogen to the coke mass in the container to produce a quenched coke mass;
• and
• removing the quenched coke mass from the container.

A method of producing coke comprising the steps of:

• providing a first container;
• disposing a volume of loose coal into the first container such that a vertical dimension of the volume of loose coal in the first container is smaller than a horizontal dimension of the volume of loose coal;
• applying a force to the volume of loose coal in the first container to produce a volume of coal forming a single compact having a density which is greater than that of the loose coal disposed in the first container;
• disposing the volume of the single compact of coal into a non-recovery type oven having an oven floor;
• heating the volume of the compact of coal to produce a coke mass;
• providing a second container;
• moving the coke mass from the oven at a substantially constant elevation to the second container;
• quenching the coke mass in the second container to produce a quenched coke mass;
• and
• removing the quenched coke mass from the second container.
