1. A coke oven, comprising:
an oven chamber including a crown and sole flues;
one or more controllable air openings positioned at the crown and/or sole flues and configured to affect temperature of the crown and/or sole flues respectively;
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 a plurality of positions including fully opened and fully closed, the uptake damper configured to control an oven draft;
a first actuator configured to alter the position of the uptake damper between the plurality of positions in response to a position instruction;
a common tunnel in fluid communication with the uptake duct, the common tunnel being configured to receive exhaust gases from the uptake duct;
at least one heat recovery steam generator in fluid communication with the common tunnel, the heat recovery steam generator including (i) a heat recovery steam generator damper positioned at any one of a plurality of positions including fully opened and fully closed and (ii) and a second actuator configured to alter the position of the heat recovery steam generator damper;
one or more sensors configured to detect an operating condition of the coke oven, wherein the one or more sensors comprises at least one of (i) a draft sensor configured to detect the oven draft, (ii) a temperature sensor configured to detect an oven chamber temperature or a sole flue temperature, or (iii) an oxygen sensor configured to detect an uptake duct oxygen concentration in the uptake duct; and
a controller in communication with the controllable air openings, the first actuator and the one or more sensors, the controller being configured to provide position instructions to at least one of (i) the first actuator to actuate the uptake damper over a coking cycle, such that a target oven draft is adjusted at least three times over the coking cycle by actuating the uptake damper, or (ii) the second actuator to actuate the heat recovery steam generator actuator, in response to the operating condition detected by the one or more sensors.
