Abstract
A pressure controller for a coke box has a fan assembly and a valve assembly selectively coupling the fan assembly to the coke box. A barometer senses a pressure level in the coke box. A control element controls a speed of the fan assembly to maintain the pressure level in the coke box below a desired pressure level.
Claims20
A pressure controller for a coke box, the pressure controller comprising:
- a fan assembly;
- a valve assembly selectively coupling the fan assembly to the coke box;
- a barometer for sensing a pressure in the coke box;
- and
- a control element for controlling a speed of the fan assembly to maintain a pressure in the coke box below a desired pressure level.
2 more elements
A pressure controlled coke box comprising:
- a coke box having an interior;
- a fan assembly;
- a valve assembly selectively coupling the fan assembly with the coke box interior;
- a barometer for sensing a pressure in the coke box;
- and
- a control element for controlling a speed of the fan assembly to maintain the pressure in the coke box below a desired level.
3 more elements
A method of preventing pressure build up in a coke box and gas flow back into a coke oven when pushing a coke charge into an interior of the coke box, the method comprising the steps of:
- providing a valve assembly on a wall of the coke box selectively communicating with the coke box interior;
- selectively coupling a fan assembly with the valve assembly for selective communication with the coke box interior;
- mounting a barometer for sensing a pressure within the coke box interior;
- and
- controlling a speed of the fan assembly to maintain the pressure within the coke box interior below a desired level.
