Abstract
A volatile matter sharing system includes a first stamp-charged coke oven, a second stamp-charged coke oven, a tunnel fluidly connecting the first stamp-charged coke oven to the second stamp-charged coke oven, and a control valve positioned in the tunnel for controlling fluid flow between the first stamp-charged coke oven and the second stamp-charged coke oven.
Claims43
A volatile matter sharing system, comprising:
- a first stamp-charged coke oven;
- a second stamp-charged coke oven;
- a tunnel fluidly connecting the first stamp-charged coke oven to the second stamp-charged coke oven;
- and
- a control valve positioned in the tunnel for controlling fluid flow between the first stamp-charged coke oven and the second stamp-charged coke oven.
A volatile matter sharing system comprising:
- a first stamp-charged coke oven and a second stamp-charged coke oven, each of the stamp-charged coke ovens including,
- an oven chamber,
- a sole flue,
- a downcomer channel fluidly connecting the oven chamber and the sole flue,
- an uptake duct in fluid communication with the sole flue, the uptake duct configured to receive exhaust gases from the oven chamber,
- an automatic uptake damper in the uptake duct and configured to be positioned in any one of a plurality of positions including fully open and fully closed according to a position instruction to control an oven draft in the oven chamber, and
- a sensor configured to detect an operating condition of the stamp-charged coke oven;
- a tunnel fluidly connecting the first stamp-charged coke oven to the second stamp-charged coke oven;
- a control valve positioned in the tunnel and configured to be positioned at any one of a plurality of positions including fully open and fully closed according to a position instruction to control fluid flow between the first stamp-charged coke oven and the second stamp-charged coke oven;
- and
- a controller in communication with the automatic uptake dampers, the control valve, and the sensors, the controller configured to provide the position instruction to each of the automatic uptake dampers and the control valve in response to the operating conditions detected by the sensors.
A method of sharing volatile matter between two stamp-charged coke ovens comprising:
- charging a first coke oven with stamp-charged coal;
- charging a second coke oven with stamp-charged coal;
- operating the second coke oven to produce volatile matter and at a second coke oven temperature at least equal to a target coking temperature;
- operating the first coke oven to produce volatile matter and at a first coke oven temperature below the target coking temperature;
- transferring volatile matter from the second coke oven to the first coke oven;
- combusting the transferred volatile matter in the first coke oven to increase the first coke oven temperature to at least the target coking temperature;
- and
- continue operating the second coke oven such that the second coke oven temperature is at least at the target coking temperature.
A method of sharing volatile matter between two stamp-charged coke ovens comprising:
- charging a first coke oven with stamp-charged coal;
- charging a second coke oven with stamp-charged coal;
- operating the first coke oven to produce volatile matter;
- operating the second coke oven to produce volatile matter;
- detecting a first coke oven temperature indicative of an overheat condition in the first coke oven;
- and
- transferring volatile matter from the first coke oven to the second coke oven to reduce the detected first coke oven temperature below the overheat condition.
A volatile matter sharing system, comprising:
- a first charged coke oven including a crown;
- a second coke oven including a crown;
- a first tunnel fluidly connecting the first coke oven to the second coke oven;
- a second tunnel fluidly connecting the first coke oven to the second coke oven, wherein at least a portion of the second tunnel is located above at least a portion of the crown of the first coke oven and above at least a portion of the crown of the second coke oven.
