Abstract
A coke oven battery modulation system, including a coke oven battery, a coke oven gas supply fluidly connected to the coke oven battery via a first conduit, an exhaust stack fluidly connected to the coke oven battery via a second conduit, a mixed gas supply fluidly connected to the first conduit via a third conduit, a nitrogen supply fluidly connected to the first conduit via a fourth conduit, the fourth conduit including a first valve and a first actuator operatively arranged to adjust the first valve, at least one sensor, and a controller operatively arranged to receive data from the at least one sensor and communicate with the first actuator to adjust the first valve.
Claims20
A coke oven battery modulation system, comprising:
- a coke oven battery;
- a coke oven gas supply fluidly connected to the coke oven battery via a first conduit;
- an exhaust stack fluidly connected to the coke oven battery via a second conduit;
- a mixed gas supply fluidly connected to the first conduit via a third conduit;
- a nitrogen supply fluidly connected to the first conduit via a fourth conduit, the fourth conduit including a first valve and a first actuator operatively arranged to adjust the first valve;
- at least one sensor;
- and
- a controller operatively arranged to receive data from the at least one sensor and communicate with the first actuator to adjust the first valve.
A method for monitoring a coke oven battery system including a coke oven battery, a stack, and a fuel supply conduit, the method comprising:
- receiving an input from one or more sensors;
- determining that an opacity of the stack is greater than a first predetermined threshold;
- determining that a specific gravity of coke oven gas supplied to the coke oven battery in the fuel supply conduit is less than a second predetermined threshold;
- and
- increasing a flow of nitrogen gas to the fuel supply conduit.
