Problems solved by technology

Because of the weight and size of the damper blocks, the baffles require large hydraulic pistons to raise and lower the damper block baffles within the ventilation ducts.
Because the extreme heat from the coke ovens, refractory damper blocks deteriorate over time and must be routinely replaced.
Replacing the bulky and heavy refractory damper blocks is labor intensive and cumbersome within the confined area of a coke oven ventilation system.
Multiple people are often required to handle the heavy cumbersome refractory damper blocks.
In addition, the often crumbling deteriorated refractory damper blocks leave debris in and around the ventilation system of the coke ovens.

Embodiment Construction

[0012]FIGS. 1-5 illustrate an embodiment of the present invention where reference numeral 10 generally designates a damper baffle for use in the ventilation system of a coke oven. FIG. 1 illustrates a conventional coke oven battery 2 incorporating damper baffle 10 into the ventilation duct 6 of each coke oven 4. For the sake of simplicity, only those parts of the coke oven and ventilation system necessary for the explanation of the present invention are explained and discussed; however, the present invention can be incorporated into any coke oven ventilation system. As shown in FIG. 2-5, damper baffle 10 is designed to replace conventional damper block baffles, while still using the conventional lift frame 30 and hydraulic lifts 40. Damper baffle 10 is mounted to a conventional base plate 32 of lift frame 30. As shown in FIGS. 4 and 5, a hydraulic lift 40 mounted under lift frame 30 raises and lowers damper baffle 10 into ventilation duct 6.

[0013]As best shown in FIG. 3, damper baff...

Abstract

The damper baffle includes a U-shaped sub-frame and a temperature resistant insulation damper mat draped over and secured upright to the sub-frame for use in the ventilation system of a coke oven. The damper mat is a thick sheet of silica needle mat, which provides the thermal barrier of the damper baffle. The sub-frame is a bent high temperature steel rod which is bolted directly to the base plate of a conventional lift frame and lift mechanism. Two pairs of support plates secure and support the mat over the sub-frame in an upright orientation. The damper baffle seeks to provide a light-weight damper baffle for use in coke ovens, which eliminates the need for the heavy and cumbersome refractory baffle blocks.

Description

[0001]This invention relates to coke ovens, and in particular damper baffles used in the ventilation system of coke ovens.BACKGROUND AND SUMMARY OF THE INVENTION[0002]Damper block baffles inside the ventilation systems of coke ovens regulate air flow through the ovens to control oven temperatures. Heretofore, damper block baffles consisted of a plurality of refractory damper blocks stacked atop a lift frame that is raised and lowered within the ventilation duct to open and close the air passage. The refractory damper blocks used in the damper block baffles are large heavy pre-cast shapes designed to withstand the high temperatures and act as a thermal barrier. Because of the weight and size of the damper blocks, the baffles require large hydraulic pistons to raise and lower the damper block baffles within the ventilation ducts.[0003]Because the extreme heat from the coke ovens, refractory damper blocks deteriorate over time and must be routinely replaced. Replacing the bulky and hea...
