Coke oven door liner assembly

In a coke oven door assembly for sealing a coke oven, having a cold face refractory liner, formed from a plurality of first abutting vertically aligned refractory layers, adapted for securement to an inner surface of a coke oven door, for sealing a coke oven opening, and a hot face refractory liner, formed from a plurality of second abutting vertically aligned refractory layers, spaced from and secured to said cold face refractory liner, the improvement comprising:

• an uppermost refractory section formed as an integral one piece unit having a bottom, a horizontally extending top portion, a first downwardly depending leg portion having a bottom wall and adapted for securement to said coke oven door in vertical alignment with said cold face refractory liner, and a second downwardly depending leg portion adapted for vertical alignment with said hot face refractory liner, said second downwardly depending leg portion being shorter than .said first downwardly depending leg portion, and a leg segment extending from said second downwardly depending leg portion to the level of the bottom of the uppermost refraction section, said uppermost refractory section having side walls and an interconnecting web spaced from said side walls between said first and second downwardly depending leg portions, extending from said horizontally extending portion to the bottom wall of said second downwardly depending leg portion, so as to enable gases flowing upwardly between said spaced hot face and cold face refractory liners to continue flow at least partially along sides of said interconnecting web of said uppermost refractory section and rise to the top portion of said oven for removal therefrom.

A coke oven door for sealing a coke oven wherein said coke oven door has:

• a metallic door panel having an inner surface;
• a cold face refractory liner secured to the inner surface of said metallic door panel;
• a hot face refractory liner spaced from and secured to said cold face refractory liner;
• and
• an uppermost refractory section formed as an integral one piece unit having a bottom, a horizontally extending top portion, a first downwardly depending leg portion secured to said coke oven door in vertical alignment with said cold face refractory liner, and a second downwardly depending leg portion in vertical alignment with said hot face refractory liner, said uppermost refractory section having side walls and an interconnecting web spaced from said side walls between said first and second downwardly depending leg portions, extending from said horizontally extending portion at least partially downwardly to said bottom, so as to enable gases flowing upwardly between said spaced hot face and cold face refractory liners to continue flow at least partially along sides of said interconnecting web of said uppermost refractory section and rise to the top portion of said oven for removal therefrom.
