Abstract
A coke oven includes an oven chamber configured to support and heat a coal bed, a castable slab below the oven chamber, and a foundation supporting the heat recovery oven. One or more beams are positioned between the castable slab and the foundation. The beams extend from a first end of the oven chamber to a second end of the oven chamber, forming a plurality of air gaps between the castable slab and the foundation. Heat from the oven chamber is dissipated by the one or more beams.
Claims14
A method comprising:
- providing a coke oven including an oven chamber, a foundation supporting the oven chamber and separated from the oven chamber by one or more air gaps, and a forced cooling system configured to force a fluid through an air gap of the one or more air gaps;
- heating a coal bed in the oven chamber;
- receiving an indication that a temperature of a limiting material of the coke oven exceeds a temperature limit, and
- after receiving the indication and while heating the coal bed in the oven chamber, activating the forced cooling system to force the fluid through the air gap.
A method for cooling a coke oven foundation, the method comprising:
- providing a coke oven system including an oven chamber, a foundation supporting the oven chamber and separated from the oven chamber by one or more air gaps, a sensor in at least one of the air gaps, a forced cooling system, and a controller operatively coupled to the sensor and the forced cooling system;
- heating a coal bed in the oven chamber;
- receiving an indication from the sensor;
- and
- based at least in part on the received indication, causing the forced cooling system to provide a fluid directed toward an air gap of the one or more air gaps.
A method for providing a cooling fluid, the method comprising:
- operatively coupling a controller to a forced cooling system including a fan, and a valve operatively coupled to the fan via a common pipe;
- receiving an indication from a sensor operatively coupled to the controller;
- and
- based on the received indication, causing, via the controller, the forced cooling system to activate the fan and actuate the valve, thereby causing a cooling fluid to be directed to an air gap between two beams positioned between a foundation and an oven chamber of a coke oven.
