Abstract:
A coke plant includes multiple coke ovens where each coke oven is adapted to produce exhaust gases, a common tunnel fluidly connected to the plurality of coke ovens and configured to receive the exhaust gases from each of the coke ovens, multiple standard heat recovery steam generators fluidly connected to the common tunnel where the ratio of coke ovens to standard heat recovery steam generators is at least 20:1, and a redundant heat recovery steam generator fluidly connected to the common tunnel where any one of the plurality of standard heat recovery steam generators and the redundant heat recovery steam generator is adapted to receive the exhaust gases from the plurality of ovens and extract heat from the exhaust gases and where the standard heat recovery steam generators and the redundant heat recovery steam generator are all connected in parallel with each other.

Claim (Index 54):
A system for coking coal comprising:\n a plurality of coke ovens, wherein each coke oven includes:\n an oven chamber; \n an uptake duct in fluid communication with the oven chamber, the uptake duct being configured to receive exhaust gases from the oven chamber; and \n an uptake damper in fluid communication with the uptake duct, the uptake damper being positioned by an actuator to any one of a plurality of positions including fully opened and fully closed; \n a common tunnel fluidly connected to the plurality of coke ovens and being configured to receive the exhaust gases from each of the coke ovens; a plurality of heat recovery steam generators fluidly connected to the common tunnel and transitionable between a normal mode and a gas sharing mode, wherein\n each heat recovery steam generator is in fluid communication with a heat recovery steam generator damper configured to be positioned by an actuator to any one of a plurality of positions including fully opened and fully closed, \n the heat recovery steam generators are configured to operate at a first capacity when in the normal mode, \n at least one heat recovery steam generator is configured to operate at a second capacity that is greater than the first capacity in the gas sharing mode, and \n at least one heat recovery steam generator is configured to operate at a third capacity that is less than the first capacity in the gas sharing mode; and \n a controller configured to initiate the gas sharing mode by providing a position instruction to at least one of the actuators to cause the at least one actuator to alter the position of at least one of the uptake dampers or heat recovery steam generator dampers to thereby maintain a target draft within the system for coking coal by directing exhaust gases from the at least one heat recovery steam generator configured to operate at the third capacity to the at least one heat recovery steam generator configured to operate at a second capacity.
