1. A method of increasing a coal processing rate of a coke oven, the method comprising:
positioning a coal charging system, having an elongated charging frame and a charging head operatively coupled with a distal end portion of the elongated charging frame, at least partially within a coke oven having a maximum designed coal charge capacity, defined as a maximum volume of coal that can be charged into the coke oven according to a width and height of the coke oven multiplied by a maximum bed height, defined by a height of downcomer openings, formed in opposing side walls of the coke oven, above a coke oven floor, and a maximum coking time associated with the maximum designed coal charge, wherein the maximum designed coking time is defined as the amount of time required to fully coke the maximum designed coal charge;
charging coal into the coke oven with the coal charging system in a manner that defines a first operational coal charge that is less than the maximum designed coal charge capacity;
coking the first operational coal charge in the coke oven at a first startup temperature until it is converted into a first coke bed but over a first coking time that is less than the maximum designed coking time;
pushing the first coke bed from the coke oven;
charging coal into the coke oven with the coal charging system in a manner that defines a second operational coal charge that is less than the maximum designed coal charge capacity;
coking the second operational coal charge in the coke oven at a second startup temperature greater than the first startup temperature until the second operational coal charge is converted into a second coke bed but over a second coking time that is less than the maximum designed coking time; and
pushing the second coke bed from the coke oven;
a sum of the first operational coal charge and the second operational coal charge exceeding a weight of the maximum designed coal charge capacity;
a sum of the first coking time and the second coking time being less than the maximum designed coking time.
